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)

We have monitored the X-ray source X-Per (4U 0352+30) on 31 August, 1979 through aU filter for about 1.5 hr using 102-cm telescope of Kavalur observatory. During this period intensity of X-Per fluctuated for some time, on ...
Periodic modulations in the optical light curves of EX Hydrae

Seetha, S; Sharma, D. P; Padmini, V. N; Marar, T. M. K; Kasturirangan, K (Kluwer Academic Publishers, 1987-02)

The authors present here new results on the periodic modulations in the optical light curves of EX Hydrae observed during 1982 - 84. The period analysis has been done using synchronous summation and discrete Fourier transform ...
Photometric Observations of the X-Ray Dwarf Nova HL Canis Majoris

Seetha, S; Marar, T. M. K; Sharma, D. P; Kasturirangan, K; Rao, U. R; Bhattacharyya, J. C (INSDOC, 1983-08)

High speed optical photometric observations of the X-ray dwarf nova HL Canis Majoris (1E 0643-1648), discovered with the Einstein Observatory, are presented. Results of long term monitoring and attempts to detect photometric ...
