Photometry and spectroscopy of II Peg, IM Peg and UX Ari

Dar, A. A; Parihar, P. S; Malik, M. A (IOP Publishing, 2018-08)

V band photometry of three RS CVn stars, II Peg, IM Peg and UX Ari, is carried out to study the physical properties of these variables. We verified the significant and regular optical photometric variability to be present ...
Search for variable stars in the open cluster NGC 2509

Dar, A. A; Parihar, P. S; Saleh, P; Malik, M. A (Elsevier B.V, 2018-10)

This work presents the first photometric variability survey of the open cluster NGC 2509 carried out in February, 2017. Data of four nights was analysed by ensemble photometry technique, using 1k Ã— 1k CCD and 1.3 m telescope ...
Variable stars in M37

Dar, A. A; Parihar, P. S; Saleh, P; Malik, M. A (IOP Publishing, 2018-12)

The CCD photometric observations of open star cluster M37 (NGC 2099) were carried out up to a limiting magnitude of V ~ 20 in both B and V filters to search for variable stars using a 2k Ã— 4k CCD and the 1.3 m telescope ...
