High speed photometry of dwarf nova EX Hydrae

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

High speed optical photometric observations of the hard X-ray source EX Hya, carried out with the reflector of the Kevalur Observatory, are presented. The observations with time resolutions of 1 s or 2 s were made on four ...
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 ...
The X-ray spectrum of the superluminal quasar 1928 + 73

Ghosh, K. K; Soundararajaperumal, S (Blackwell Publishing, 1992-02)

Exosat observations (0.1-10 keV) of the radio-loud quasar 1928 + 73, which displays superluminal motion, were made at four epochs between 1983/283 and 1984/009, and spectra of this source are obtained from the Exosat ...
