General classification of light curves using extreme boosting
Refilwe Kgoadi, Chris Engelbrecht, Ian Whittingham +1
A significant degree of misclassification of variable stars through the application of machine learning methods to survey data motivates a search for more reliable and accurate mac…
Rotational modulation in TESS B stars
L. A. Balona, G. Handler, S. Chowdhury +6
Light curves and periodograms of 160 B stars observed by the TESS space mission and 29 main-sequence B stars from Kepler and K2 were used to classify the variability type. There ar…
A study of Pulsation & Rotation in a sample of A-K type stars in the Kepler field
Sowgata Chowdhury, Santosh Joshi, Chris A. Engelbrecht +3
We present the results of time-series photometric analysis of 15106 A-K type stars observed by the Kepler space mission. We identified 513 new rotational variables and measured the…
The hot Gamma-Doradus and Maia stars
L. A. Balona, C. A. Engelbrecht, Yogesh C. Joshi +8
The hot ~Doradus stars have multiple low frequencies characteristic of ~Dor or SPB variables, but are located between the red edge of the SPB and the blue edge of the ~Dor…
Extensive study of HD 25558, a long-period double-lined binary with two SPB components
Á. Sódor, P. De Cat, D. J. Wright +33
We carried out an extensive observational study of the Slowly Pulsating B (SPB) star, HD 25558. The ~2000 spectra obtained at different observatories, the ground-based and MOST sat…
Kepler observations of variability in B-type stars
L. A. Balona, A. Pigulski, P. De Cat +27
The analysis of the light curves of 48 B-type stars observed by Kepler is presented. Among these are 15 pulsating stars, all of which show low frequencies characteristic of SPB sta…
