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…
Filling the gap between synchronized and non-synchronized sdBs in short-period sdBV+dM binaries with TESS: TIC 137608661, a new system with a well defined rotational splitting
Roberto Silvotti, Péter Németh, John H. Telting +5
TIC137608661/TYC4544-2658-1/FBS0938+788 is a new sdBV+dM reflection-effect binary discovered by the TESS space mission with an orbital period of 7.21 hours. In addition to the orbi…
A search for variable subdwarf B stars in TESS Full Frame Images II. Variable objects in the northern ecliptic hemisphere
A. S. Baran, S. K. Sahoo, S. Sanjayan +1
We report the results of our search for pulsating subdwarf B stars in Full Frame Images collected during Year 2 of the TESS mission and covering the northern ecliptic hemisphere. T…
Space observations of AA Doradus provide consistent mass determinations. New HW-Vir systems observed with TESS
A. S. Baran, R. H. Østensen, U. Heber +5
We present an overview of eclipsing systems of the HW-Virginis type, based on space observations from the TESS Mission. We perform a detailed analysis of the properties of AA Dor,…
Evolutionary modelling of subdwarf B stars using MESA with the predictive mixing and convective premixing schemes
J. Ostrowski, A. Baran, S. Sanjayan +1
Results of evolutionary modelling of subdwarf B stars are presented. For the first time, we explore the core and near-core mixing in the subdwarf B stars using new algorithms avail…
Mode identification in three pulsating hot subdwarfs observed with TESS satellite
S. K. Sahoo, A. S. Baran, U. Heber +12
We report on the detection of pulsations of three pulsating subdwarf B stars observed by the TESS satellite and our results of mode identification in these stars based on an asympt…
