Pulsation among TESS A and B stars and the Maia variables
Luis A Balona, Dogus Ozuyar
Classification of over 50000 TESS stars in sectors 1-18 has resulted in the detection of 766 pulsating main sequence B stars as well as over 5000 Scuti, 2300 Doradus and 11…
TESS observations of Be stars: a new interpretation
Luis A. Balona, Dogus Ozuyar
Light curves of 57 classical Be stars in TESS sectors 1 - 15 are examined. In most Be stars, the periodogram shows groups at a fundamental and one or more harmonics, which we attri…
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…
Refined Chemical Abundances of Pi Dra and HR 7545 with ATLAS12
Doğuş Özuyar, Aslı Elmaslı, Şeyma Çalışkan
We present the more refined abundances of elements (C, O, Na, Mg, Al, Si, Ca, Sc, Ti, V, Cr, Mn, Fe, Ni, Zn, Sr, Y, Zr and Ba) determined using the computationally intensive ATLAS1…
The Be Phenomenon in the Mono-Periodic STEREO Star; 13 Tau
Dogus Ozuyar, Ian R. Stevens
13\,Tau is a rarely studied bright B9V type star ({\sl V} = 5.68 mag), which shows a weak and double-peaked H{} emission profile in its spectra. In this study, we presented high…
STEREO observations of HD 90386 (RX Sex): a Delta Scuti or a hybrid star?
Dogus Ozuyar, Ian R. Stevens, Gemma Whittaker +1
HD 90386 is a rarely studied bright A2V type Delta Scuti star (V = 6.66 mag). It displays short-term light curve variations which are originated due to either a beating phenomenon…
