Gravitational searchlight and its astrophysical applications

Chitre, S. M; Narlikar, J. V; Kapoor, R. C (Nature Publishing Group, 1974-12)

Attention is given to an interesting effect associated with light emitted in the forward direction by a source circulating in an equatorial plane around a highly collapsed object or a black hole. The emitted light received ...
HD 81410 - A new RS CVn binary

Raveendran, A. V; Mekkaden, M. V; Mohin, S (Royal Astronomical Society, 1982-05)

B and V photometry of HD 81410 obtained on 34 nights between January 3 and March 14 of 1981 is presented. In both B and V, the amplitudes are found to be approximately 0.15 mag. It is also found that a 12.86833 day period ...
Orbit of the spectroscopic binary B Persei

Rajamohan, R; Parthasarathy, M (Indian Academy of Sciences, 1975-04)

Spectroscopic orbital elements are derived for the close binary system b Persei on the basis of forty spectrograms. The period is redetermined as 1.527360 days, and variations in the orbital elements are confirmed by ...
Spectroscopic observations of Nu Centauri

Ashoka, B. N; Surendiranath, R; Kameswara Rao, N (Copernicus Foundation for Polish Astronomy, 1985)

Presented are radial-velocity observations of the single-line spectroscopic binary and Beta Cephei-type variable Nu Cen, obtained in the period 1983-1984. New orbital elements have been determined by combining these ...
