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…
LAMOST J045019.27+394758.7, with peculiar abundances of N, Na, V, Zn, is possibly a Sculptor dwarf galaxy escapee
Meenakshi Purandardas, Aruna Goswami, J. Shejeelammal +5
We present the results of the high-resolution (R60,000) spectroscopic analysis of the star LAMOSTJ045019.27+394758.7 (hereafter J045) from the list of carbon stars of LAMOST…
Optical Observations of star clusters NGC 1513 and NGC 4147; white dwarf WD1145+017 and band imaging of star forming region Sh2-61 with the 3.6 meter Devasthal Optical Telescope
Ram Sagar, R. K. S. Yadav, S. B. Pandey +3
The CCD photometric data of open star cluster NGC 1513 are obtained with the 3.6-m Indo-Belgian Devasthal optical telescope (DOT). Analyses of the GAIA EDR3 astrometric dat…
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…
