  • The outburst and nature of young eruptive low mass stars in dark clouds 
    Ninan, J. P; Ojha, D. K; Bhatt, B. C; Mallick, K. K; Tej, A; Sahu, D. K; Ghosh, S. K; Mohan, V (Astronomical Society of India, 2012)
    The FU Orionis (FUor) or EX Orionis (EXor) phenomenon has attracted increasing attention in recent years and is now accepted as a crucial element in the early evolution of low-mass stars. FUor and EXor eruptions of young ...
  • THE VARIABLE STAR POPULATION IN THE GLOBULAR CLUSTER NGC 6934 
    Yepez, M. A; Ferro, A. A; Muneer, S; Giridhar, S (Instituto de Astronomia, 2018-04)
    We report an analysis of new V and I CCD time-series photometry of the globular cluster NGC 6934. Through the Fourier decomposition of the RR Lyrae light curves the mean values of [Fe/H] and the distance of the cluster ...
  • Variable stars in Palomar 13; an evaporating globular cluster 
    Yepez, M. A; Ferro, A. A; Schoeder, K. P; Muneer, S; Giridhar, S; Allen, C (Elsevier B.V, 2019-08)
    We present new CCD VI photometry of the distant globular cluster Pal 13. Fourier decomposition of the light curves of the three cluster member RRab stars lead to estimations of [Fe/H] = −1.65, and a distance of 23.67 ± ...
