Portraying The Hosts: Stellar Science From Planet Searches

 A Cool Stars 18 Splinter Session

Conveners: 

Bárbara Rojas-Ayala (CAUP)

Isabelle Boisse (Laboratoire d'Astrophysique de Marseille) 

Philip Muirhead (Boston University)


Scientific Motivation

The discovery of new worlds has driven efforts to characterize in detail the properties of their host stars.  For a given planet hosting star, we want to know its size, mass, age, effective temperature, metallicity, activity cycle and any other physical features that would aid in understanding the corresponding planetary system.  Fortuitously, much of the characterization can be done using the same data that enabled the initial planet discoveries.  The spectra obtained from radial velocity surveys, and the photometry and imaging data from transit and microlensing surveys, contain a wealth of information about the host stars' atmospheres, interiors and prior evolution.
The goal of this session is to highlight and review some of the results concerning stellar science from the past 20 years of planet surveys, to promote dialogue to encourage new ideas about existing and future planet survey data, and to provide answers to the following questions:

1) What stellar information can we infer from RV, transit, microlensing and direct detection data?
2) What are the current caveats, limitations and challenges when interpreting the results? 
3)How will new instruments and missions transform our understanding of cool stars?
