The Public Photometry Pipelines for Exoplanets

Abstract

Over the past decade, exoplanet atmospheric characterization has became what some might call the cosmology of astronomy. In an attempt to extract and understand the weak planetary signals (a few percent down to a few tens of ppm times that of their host-star signals), researchers have developed dozens of idealized planetary atmospheric models. Physical interpretations hinge on pretending that we understand stellar signals (as well behaved mostly temporarily static spherical cows), as well as planetary signals (as unidimensional objects, or sometimes quasi-multidimensional objects). The discovery of small and cool planets has lead to analyze planetary signals well below the designed photometric precision of current instrumentation. The challenge is up there, and keep us busy, so all is well. Here we present yet another open-source tool to analyze exoplanet data of time-series observations. The {\puppies} code is available via PyPI (\texttt{pip install exo-puppies}) and conda, the documentation is located at https://puppies.rtfd.io
