Physics of stars and measurement data

Astrophysics = the star physics was beginning its development without a supporting of measurement data, which could not be obtained then. Still astrophysics exists without this support, although now astronomers collected a lot of valuable information. This is the main difference of astrophysics from all other branches of physics, for which foundations are measurement data. The creation of the theory of stars, which is based on the astronomical measurements data, is one of the main goals of modern astrophysics. Below the principal elements of star physics based on data of astronomical measurements are described. The theoretical description of a hot star interior is obtained. It explains the distribution of stars over their masses, mass-radius-temperature and mass-luminosity dependencies. The theory of the apsidal rotation of binary stars and the spectrum of solar oscillation is considered. All theoretical predictions are in a good agreement with the known measurement data, which confirms the validity of this consideration.

The thermo-magnetic effect in metals

The magnetic field which induced by the thermo-electric current in metals was detected and measured using of a flux-gate magnetometer. It is shown that the application of a temperature gradient on a metal rod gives rise to a circulating current therein and induces a magnetic field in the vicinity of its surface. If a temperature gradient on a metal rod exists, the "hot"\ electrons flow from the heated region of a metal into a colder region and extrude "cold" electrons that form a current in opposite direction. Since the oppositely directed currents repel each other due to the interaction of magnetic fields, a convective loop of electron current formes inside a metalic sample. The magnetic field of this convection is directly proportional to the temperature gradient, the metal conductivity and inversely proportional to the temperature squared.

Superconductivity and Superfluidity

Currently there is a common belief that the explanation of superconductivity phenomenon lies in understanding the mechanism of the formation of electron pairs. Paired electrons, however, cannot form a superconducting condensate spontaneously. These paired electrons perform disorderly zero-point oscillations and there are no force of attraction in their ensemble. In order to create a unified ensemble of particles, the pairs must order their zero-point fluctuations so that an attraction between the particles appears. As a result of this ordering of zero-point oscillations in the electron gas, superconductivity arises. This model of condensation of zero-point oscillations creates the possibility of being able to obtain estimates for the critical parameters of elementary superconductors, which are in satisfactory agreement with the measured data. On the another hand, the phenomenon of superfluidity in He-4 and He-3 can be similarly explained, due to the ordering of zero-point fluctuations. It is therefore established that both related phenomena are based on the same physical mechanism.

Superconductivity, superfluidity and zero-point oscillations

Currently it is thought that in order to explain the phenomenon of superconductivity is necessary to understand the mechanism of formation of electron pairs. However, the paired electrons cannot form a superconducting condensate. They perform disorderly zero-point oscillations and there are no attractive forces in their ensemble. To create a unified ensemble of particles, the pairs must order their zero-point fluctuations so that an attraction between the particles appears. For this reason, the ordering of zero-point oscillations in the electron gas is the cause of superconductivity and the parameters characterizing this order determine the properties of superconductors. The model of condensation of zero-point oscillations creates the possibility to obtain estimates for the critical parameters of elementary superconductors, which are also in the satisfactory agreement with measured data. On the another hand, the phenomenon of superfluidity in He-4 and He-3 can be similarly explained due to the ordering of zero-point fluctuations. Thus it is established that the both related phenomena are based on the same physical mechanism.

Superfluidity as sequence of an ordering of zero-point oscillations

The phenomenon of superconductivity was explained as a consequence of ordering of zero-point oscillations. Superfluidity are related phenomenon. The consideration of interaction zero-point oscillations in liquid helium permit to obtain quantitative estimations of main characteristic of superfluid helium which are in a good agreement with measuring data. So both related phenomena, superconductivity and superfluidity, get explanation which is based on the same physical mechanism - they both are consequences of the ordering of zero-point oscillations.

The critical temperature of superconductor and its electronic specific heat

It is shown that the critical temperature of the superconductor is related to the Sommerfeld constant, i.e. it is determined by the Fermi energy for I-type superconductors. The estimation of properties of II-type superconductors reveals a somewhat different relation of critical temperature and Fermi energy. Among the high-temperature superconducting ceramics there are the both - I and II - types superconductors.

Does one need to consider superconductivity as Bose-Einstein condensation?

It is shown that the temperature dependence of the value of energy gap in superconductors can be classified as the order-disorder transition with its characteristic features. The obtained relationship between the critical temperature and the critical magnetic field of the condensate of electrically charged particles is in accordance with measurement data of superconductors.

The physical approach to the hot star description

The theoretical discription of a hot star interior is obtained. It explains the distribution of stars over their masses, mass-radius-temperature and mass-luminosity dependencies. The theory of the apsidal rotation of binary stars and the spectrum of solar oscillation is considered. All obrained theoretical predictions are in a good agreement with the known measurement data, which confirms the validity of this consideration.

The comparison of theoretical predictions with measuring data of stellar parameters

The Euler equation has been accepted as the basic postulate of stellar physics long before the plasma physics was developed. The existence of electrical interaction between particles of interstellar plasma poses the question, how this interaction must be accounted for. We argue that the right way is in formulation of a new postulate. On the base of the new postulate, the theory of a hot star interior is developed. Using this theory we obtain the distribution of stars over their masses and mass-radius, mass-temperature and mass-luminosity dependencies. The theory of the apsidal rotation of binary stars and the spectrum of solar oscillation is considered. All these theoretical predictions are in a good agreement with the known measurement data, which confirms the validity of this consideration.

Two alternative approaches to a stellar interior theory. Which of them is correct?

All fundamental physical principles are confirmed by numerous experiments and practical certainty and have unambiguous interpretation. But physics of stars is based on few measured effects only. It gives some freedom for figments of the imagination. The goal of this paper is to compare two alternative astrophysical models with measurement data.

The main frequencies of solar core natural oscillations

The oscillations of a spherical body consisting of hot electron-nuclear plasma are considered. It is shown that there are two basic modes of oscillations. The estimation of the main frequencies of the solar core oscillation gives a satisfactory fit of the calculated spectrum and the measurement data.

The angular velocity of the apsidal rotation in binary stars

The shape of a rotating star consisting of equilibrium plasma is considered. The velocity of apsidal rotation of close binary stars (periastron rotation) which depends on the star shapes is calculated. The obtained estimations are in a good agreement with the observation data of the apsidal motion in binary systems.

The equilibrium state of the dense electron-nuclear plasma in the self-gravitational field. The stellar mass distribution and stellar magnetic fields

The equilibrium of dense plasma in a self-gravitation is considered. The obtained results radically distinguish from the point of view which is commonly accepted in the astrophysical society. It is important that all these results were obtained without any disputable speculative assumptions. They were obtained on the standard physical base by standard formal methods. The novelty of the obtained results is based on a rejection of the oversimplified ideal gas approximation which is usually accepted for a star interior description and on a taking into consideration the electron-nuclear plasma features. It was shown that there is the minimum for plasma energy at a density and a temperature which determines the equilibrium state of plasma in the self-gravitation at zero gradient of the general parameters of plasma. This effect plays an important role for astrophysics. It enables to explain the mechanism of the star magnetic field generation and to make a prediction for the spectrum of star masses with a quite satisfactory agreement for the observation data.
