  • Exploring pre-main sequence variables of ONC: the new variables 
    Parihar, P. S; Messina, S; Distefano, E; Shantikumar, N. S; Medhi, B. J (Wiley Blackwell, 2009-07)
    Since 2004, we have been engaged in a long-term observing program to monitor young stellar objects in the Orion Nebula Cluster. We have collected about two thousands frames in V, R, and I broad-band filters on more than ...
  • FR Cnc revisited: photometry, polarimetry and spectroscopy 
    Golovin, A; Galvez-Ortiz, M. C; Hernan-Obispo, M; Andreev, M; Barnes, J. R; Montes, D; Pavlenko, E; Pandey, J. C; Martinez-Arnaiz, R; Medhi, B. J; Parihar, P. S; Henden, A; Sergeev, A; Zaitsev, S. V; Karpov, N (Wiley-Blackwell, 2012-03)
    This paper is part of a multiwavelength study aimed at using complementary photometric, polarimetric and spectroscopic data to achieve an understanding of the activity process in late-type stars. Here, we present the ...
  • Results from a spectroscopic survey in the CoRoT fields. I. Search for chromospherically active stars 
    Medhi, B. J; Messina, S; Parihar, P. S; Pagano, I; Muneer, S; Duorah, K (EDP Sciences, 2007-07)
    Aims.In this paper we report the results of the spectroscopic survey we carried out to detect chromospheric activity of late-type stars in the fields of view of the CoRoT space mission. Methods.We give an accurate MK ...
  • Spectroscopic survey of ASAS eclipsing variables: search for chromospherically active eclipsing binary stars - I 
    Parihar, P. S; Messina, S; Bama, P; Medhi, B. J; Muneer, S; Velu, C; Ahmad, A (Royal Astronomical Society, 2009-05)
    We have started a spectroscopic survey to identify new chromospherically active components and low-mass pre-main sequence (PMS) stars in recently discovered All Sky Automated Survey (ASAS) eclipsing binaries. In this paper, ...
