Companions to Kepler giant stars: A long-period eccentric substellar companion to KIC 3526061 and a stellar companion to HD 187878
Marie Karjalainen, Raine Karjalainen, Artie P. Hatzes +12
Context. Our knowledge of populations and occurrence of planets orbiting evolved intermediate-mass stars is still incomplete. In 2010 we started a planet-search program among 95 gi…
Periodic variable A-F spectral type stars in the northern TESS continuous viewing zone
M. Skarka, J. Žák, M. Fedurco +11
The goal of our study is to provide a reliable classification of variability of A-F stars brighter than 11 mag located in the northern TESS continuous viewing zone. We also aim at…
Occultations from an active accretion disk in a 72 day detached post-Algol system detected by K2
G. Zhou, S. Rappaport, L. Nelson +28
Disks in binary systems can cause exotic eclipsing events. MWC 882 (BD-22 4376, EPIC 225300403) is such a disk-eclipsing system identified from observations during Campaign 11 of t…
The Radial Velocity Variability of the K-giant Gamma Draconis: Stellar Variability Masquerading as a Planet
A. P. Hatzes, M. Endl, W. D. Cochran +9
We present precise stellar radial velocity measurements of Gamma Dra taken from 2003 to 2017. The data from 2003 to 2011 show coherent, long-lived variations with a period of 702 d…
