Lunar occultation techniques in investigations of binary stars

Bhattacharyya, J. C (Tira Pustaka, Jakarta, 1984)

The paper discusses the possibility of direct measurement of angular separations and luminosity ratios of components of unresolved binary systems through observations of lunar occultations. A current program at Kavalur ...
Observations of X-Per in optical domain

Sharma, D. P; Nagaraja, B. V; Bhattacharyya, J. C; Mohin, S; Raveendran, A. V (Kluwer Academic Publishers, 1983-09)
