Implementaci\'on de un nuevo algoritmo de identificaci\'on de fuentes estelares en el c\'odigo SACAMAN

An improved version of the identification stellar sources module in the quasi-automatic SACAMAN code is presented, which allows to obtain YZJHKs-VVV magnitudes for a set of predefined objects. The procedure uses a proximity algorithm $\simeq$ 70 less time-consuming than the previous method of successive and counting approximation. This code is being applied to the study of variability of carbon stars belonging to the Galactic Bulge.

VISTA Variables in the V\'ia L\'actea (VVV): Halfway Status and Results

The VISTA Variables in the V\'ia L\'actea (VVV) survey is one of six public ESO surveys, and is now in its 4th year of observing. Although far from being complete, the VVV survey has already delivered many results, some directly connected to the intended science goals (detection of variables stars, microlensing events, new star clusters), others concerning more exotic objects, e.g. novae. Now, at the end of the fourth observing period, and comprising roughly 50% of the proposed observations, the actual status of the survey, as well some of the results based on the VVV data, are presented.
