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…
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…
Pulsating subdwarf B stars in the oldest open cluster NGC6791
S. Sanjayan, A. S. Baran, J. Ostrowski +6
We report results of our analysis of the Kepler superaperture LC data of the open cluster NGC6791 to search for pulsating sdB stars. We checked all pixels and we found only three s…
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…
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…
A search for variable subdwarf B stars in TESS Full Frame Images -- I. Variable objects in the southern ecliptic hemisphere
S. K. Sahoo, A. S. Baran, S. Sanjayan +1
We report the results of our search for pulsating subdwarf B stars in Full Frame Images, sampled at 30 min cadence and collected during Year 1 of the TESS mission. Year 1 covers mo…
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…
