Titolo: The star-planet connection: finding and characterizing new Earths
-----
Abstract:
Proper characterization of the host star to a planet is a key element to the interpretation and to the understanding of planetary data. The star has an impact on two major aspects: i) by introducing potential sources of systematic errors (e.g., surface spots) in our measurements, and ii) through the modification of the structure and evolution of the planet atmosphere by being the overwhelmingly larger source of energy. The star plays a central role in shaping the structure, evolution, and even determining the mere existence of planetary atmospheres. The vast majority of the stellar flux is well characterized thanks to the impressive progress made in the modeling of stellar atmospheres. At short wavelengths (X-rays to UV) and in particle emissions, however, the information is scarcer. In this talk I will review our current understanding of the flux and particle emissions of the Sun and low-mass stars in the context of planetary atmospheres.
