SAO 75669: A late type giant behind the molecular cloud MBM 12

Bhatt, H. C; Sagar, R; Subramaniam, A; Gorti, U; Chandrasekhar, T; Ashok, N. M; Ragland, S (European Southern Observatory, 1994-09)

Photometric and spectroscopic observations of the star SAO 75669 in the region of the high galactic latitude molecular cloud MBM 12 are presented. The optical, near-infrared and far-infrared IRAS photometric magnitudes ...
Spectroscopic studies of the solar corona during total solar eclipse of October 24, 1995

Ananda Rao, B. G; Ashok, N. M; Chandrasekhar, T; Desai, J. N; Nanda Kumar, M. S (Indian Institute of Astrophysics, 1997)

We have obtained Fabry-Perot Interferograms of the solar corona during the 1995 total solar eclipse, in two emission lines, Fe X line at 6374Å and Fe XIV line at s303 Å. We have also obtained a Fabry-perot-gram of the ...
A two channel high speed photometer for lunar occultation studies in the near - IR

Mondal, S; Chandrasekhar, T; Ashok, N. M; Kikani, P. K (Astronomical Society of India, 1999)

Lunar occultaion in the near infrared has been demonstrated by the PRL group to be an effective method of determining the angular size (in milliarcsecond range)and accurate effective temperature of red giants, supergiants ...
