Characterization of Eclipsing Binary System EPIC 211982753
Alaxender Panchal, Yogesh C. Joshi
We present the physical parameters of an eclipsing binary system EPIC 211982753 derived through photometric and radial velocity data modeling. We make use of photometric data from…
Investigation of orbital period changes in 9 contact binaries
Yogesh C. Joshi, Alaxendra Panchal
We present the results for orbital period analysis of 9 contact binaries (CBs). The photometric data analyzed in this work is collected using ARIES 1-m and 1.3-m telescopes as well…
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…
Optical characterization and Radial velocity monitoring with Belgian and Indian Telescopes (ORBIT): the eclipsing binaries EPIC 211982753 and EPIC 211915147
Alaxender Panchal, Y. C. Joshi, Peter De Cat +3
The K2 eclipsing binary candidates EPIC 211982753 (hereinafter called EPIC2753) and EPIC 211915147 (hereinafter called EPIC5147) are characterized with the help of photometric and…
Photometric study of the young open clusters IC 1442, King 21, and Trumpler 7
Jayanand Maurya, Y. C. Joshi, A. S. Gour
We carried out UBVRcIc photometric study of three poorly studied young open clusters IC 1442, King 21, and Trumpler 7 (Tr 7). We obtained 263, 244, and 128 member stars using Gaia…
Photometric and Kinematic study of the three intermediate age open clusters NGC 381, NGC 2360, and Berkeley 68
Jayanand Maurya, Y. C. Joshi
We present UBVRcIc photometric study of three intermediate age open star clusters NGC 381, NGC 2360, and Berkeley 68 (Be 68). We examine the cluster membership of stars using recen…
