Spectroscopic binaries in the BEAST B-star sample

Vortrag von Lukas Stock in der Junge AG Kolloquiumsreihe

Veranstaltungsdaten

Most explanets were found at low mass stars. The BEAST survey wants to expand the range of host stars to B type stars using direct imaging. Knowing the properties of the host stars is very important for estimating parameters and stability of the exoplanets orbit. I will present first results of radial velocity analysis and athmospheric model fitting for B type stars, achieving RV errors less than 100 m/s. I will also present the data reduction software CERES, which I expanded and ported to Python3.
