SPECTROSCOPY OF BRIGHT ALGOL-TYPE SEMI-DETACHED CLOSE BINARY SYSTEM HU TAURI (HR 1471)

Parthasarathy, M (Konkoly Observatory, 2018-01-23)

Radial velocities of the primary component (B8V) of HU Tauri derived from the photographic spectra obtained during January 1974 to December 1974 and spectroscopic orbital elements from the analysis of the radial velocity ...
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 ...
ɛ Aur in eclipse: Post-AGB primary and disk-shaped secondary

Muthumariappan, C; Parthasarathy, M; Jayakumar, K; Appakutty, M (Cambridge University Press, 2012-08)

We present physical and chemcal properties of the disk in the eclipsing binary system ɛ Aur by solving 2D radiative transfer problem. We also present preliminary results of our high resolution spectroscopic monitoring of ...
