Search for Stellar Companions of Exoplanet Host Stars with AstraLux/CAHA 2.2 m
S. Schlagenhauf, M. Mugrauer, C. Ginski +3
Stellar multiplicity is a key aspect of exoplanet diversity, as the presence of more than one star in a planetary system can have both devastating and positive effects on its forma…
A multiplicity study of transiting exoplanet host stars. II. Revised properties of transiting planetary systems with companions
J. Southworth, A. J. Bohn, M. A. Kenworthy +2
We perform a detailed study of six transiting planetary systems with relatively bright stars close enough to affect observations of these systems. Light curves are analysed taking…
A multiplicity study of transiting exoplanet host stars. I. High-contrast imaging with VLT/SPHERE
A. J. Bohn, J. Southworth, C. Ginski +3
We study the multiplicity of host stars to known transiting extra-solar planets to test competing theories on the formation mechanisms of hot Jupiters. We observed 45 exoplanet hos…
YETI observations of the young transiting planet candidate CVSO 30 b
St. Raetz, T. O. B. Schmidt, S. Czesla +32
CVSO 30 is a unique young low-mass system, because, for the first time, a close-in transiting and a wide directly imaged planet candidates are found around a common host star. The…
