Precise and accurate planetary parameters (mass, radius, and mean density) are needed to distinguish between solid rocky, water rich, gaseous, or otherwise composed planets. A key aspect
to this progress is the characterization of the planet host stars. For instance, precise and accurate stellar radii are critical if we want to measure precise and accurate values of the radius of a transiting planet. The determination of the stellar radius is in turn dependent on the quality of the derived stellar atmospheric parameters such as the effective temperature.
In this seminar I will present a new tool, FASMA, to developed at IA to obtain these stellar parameters. FASMA is build as a web application written in Python and hosted on www.iastro.pt/fasma. The idea is for people to have easy access to this tool and thus the derivation of stellar parameters.
