Exoplanets, stellar activity, and the star-planet connection

Conveners: Ansgar Reiners, Jacob Bean, Klaus Strassmeier, Sami Solanki

With more than 300 extrasolar planets found, the quest for planetary systems other than ours has entered a new phase. Lower-mass planets are being discovered, the physical properties of planets are being measured, and stars substantially different from the Sun are being monitored. The goals of this quest are manifold: a) Understanding the structure, formation, and evolution of different types of planets through observations of planet frequency and characteristics as a function of stellar parameters; b) Constraining stellar environments, in particular the influence of stellar activity; c) Unterstanding the physics of interactions between stars and planets; and d) Finding an Earth analogue.

The splinter will cover and connect the topics related to this field with an emphasis on ongoing and planned efforts to detect and characterize extrasolar planets, to study stellar activity, and to shed light on the interaction between stars and planets.
