Study of instabilities and outbursts in luminous blue variables AF And R 127
Abhay Pratap Yadav, Sugyan Parida, Yogesh Chandra Joshi +1
Luminous blue variables (LBVs) are evolved massive stars close to the Eddington limit, with a distinct spectroscopic and photometric variability having unsteady mass-loss rates. Th…
High-precision photometric and high-resolution spectroscopic characterisation of HD 180347
Otto Trust, Lyudmila Mashonkina, Edward Jurua +3
We report the analysis of high-precision space-based photometric and high-resolution spectroscopic observations of HD 180347. The high-quality light curves from the Transiting Exop…
Photometric variable stars in the young open cluster NGC 6823
Sneh Lata, W. P. Chen, J. C. Pandey +8
We present stellar variability towards the young open cluster NGC\,6823. Time series - and -band CCD photometry led to identification and characterization of 88 variable star…
Study of Chemically Peculiar Stars-I : High-resolution Spectroscopy and K2 Photometry of Am Stars in the Region of M44
Santosh Joshi, Otto Trust, E. Semenko +30
We present a study based on the high-resolution spectroscopy and K2 space photometry of five chemically peculiar stars in the region of the open cluster M44. The analysis of the hi…
Rotation and spots in normal A and Am/Fm stars
Otto Trust, Edward Jurua, Peter De Cat +1
Frequency analysis of long-term ultra-precise photometry can lead to precise values of rotation frequencies of rotating stars with ``hump and spike'' features in their periodograms…
HERMES spectroscopy of normal A and Am stars
Otto Trust, Edward Jurua, Peter De Cat +2
The nominal Kepler mission provided very high-precision photometric data. Using these data, interesting phenomena such as spots, and ``hump and spike'' features were observed in th…
