An Eclipsing 47 minute Double White Dwarf Binary at 400 pc
James Munday, P. -E. Tremblay, J. J. Hermes +20
We present the discovery of the eclipsing double white dwarf (WD) binary WDJ 022558.21-692025.38 that has an orbital period of 47.19 min. Following identification with the Transiti…
A variable star population in the open cluster NGC 6791 observed by the Kepler spacecraft
Sachu Sanjayan, Andrzej S Baran, Peter Nemeth +3
We present the list of variable stars we found in the Kepler superstamp data covering approximately 9 arcminutes from the central region of NGC 6791. We classified the variable sta…
Variable Blue Straggler Stars in Open Cluster NGC 6819 Observed in the Kepler 'Superstamp' Field
Joyce A. Guzik, Andrzej S. Baran, Sachu Sanjayan +4
NGC 6819 is an open cluster of age 2.4 Gyr that was in the NASA Kepler spacecraft field of view from 2009 to 2013. The central part of the cluster was observed in a 200 x 200 pixel…
A search for variable subdwarf B stars in TESS Full Frame Images III. An update on variable targets in both ecliptic hemispheres -- contamination analysis and new sdB pulsators
S. K. Sahoo, A. S. Baran, H. L. Worters +2
We present an update on the variable star survey performed on the TESS 30 min Full Frame Image (FFI) data reported by our first two papers in this series. This update includes a co…
Asteroseismology of hot subdwarf B stars observed with TESS: discovery of two new gravity mode pulsating stars
Murat Uzundag, Roberto Silvotti, Andrzej S. Baran +4
TIC033834484 and TIC309658435 are long-period pulsating subdwarf B star, which were observed extensively (675 and 621 days, respectively) by the Transiting Exoplanet Survey Satelli…
Short-period pulsating hot-subdwarf stars observed by TESS I. Southern ecliptic hemisphere
A. S. Baran, V. Van Grootel, R. H. Ostensen +7
We present results of a Transiting Exoplanet Survey Satellite (TESS) search for short-period pulsations in compact stellar objects observed in years 1 and 3 of the TESS mission, du…
