Exoplanets stars: database of host-star multi-waveband properties

Properties of the exoplanet host stars are key factors to understanding the environment within which the exoplanet lies and estimating the energy inputs to its atmosphere. This influence comes by two different ways: the basic properties of the star have an obvious effect on the planet and in particular, X-ray and UV luminosity affect the formation and the atmospheric properties of the planets; on the other hand, stellar parameters such as its luminosity, effective temperature and radius have an impact in the retrieval process of the planetary-atmosphere properties and on its errors. Therefore, a fully characterized host star is a mandatory first step for ExoplANETS-A and for its main goal.
