Discovery of new TESS pulsating hot subdwarfs
J. Krzesinski, L. A. Balona
This work is dedicated to a search for new pulsating hot subdwarfs in TESS photometric data which could have been missed in previous searches. By matching catalogues of hot subdwar…
On X-ray pulsations in beta Cephei-type variables
L. M. Oskinova, H. Todt, D. P. Huenemoerder +4
Beta Cephei-type variables are early B-type stars that are characterized by oscillations observable in their optical light curves. At least one Beta Cep-variable also shows periodi…
Asteroseismology of KIC 11754974: a high-amplitude SX Phe pulsator in a 343-day binary system
S. J. Murphy, A. Pigulski, D. W. Kurtz +13
The candidate SX Phe star KIC 11754974 shows a remarkably high number of combination frequencies in the Fourier amplitude spectrum: 123 of the 166 frequencies in our multi-frequenc…
Photometric Study and Detection of Variable Stars in the Open Clusters - I : NGC 6866
Yogesh C. Joshi, Santosh Joshi, Brijesh Kumar +2
We present results of a variability search in the intermediate-age open cluster NGC 6866 from 29 nights over two observing seasons. We find 28 periodic variables, of which 19 are n…
First science with SALT: peering at the accreting polar caps of the eclipsing polar SDSS J015543.40+002807.2
D. O'Donoghue, D. A. H. Buckley, L. A. Balona +48
We describe briefly the properties of the recently completed Southern African Large Telescope (SALT), along with its first light imager SALTICAM. Using this instrument, we present…
Asteroseismological studies of three Beta Cephei stars: IL Vel, V433 Car and KZ Mus
G. Handler, R. R. Shobbrook, F. F. Vuthela +3
We have acquired between 127 and 150 h of time-resolved multicolour photometry for each of the three Beta Cephei stars IL Vel, V433 Car and KZ Mus over a time span of four months f…
