  • Detection of an extremely active state of AM Canum Venaticorum 
    Kutty, K. R. N; Marar, T. M. K; Padmini, V. N; Seetha, S; Kasturirangan, K; Rao, U. R; Bhattacharyya, J. C; Mohin, S; Jayakumar, K (D. Reidel Publishing Co., 1986)
    We report fast photometric observations of AM Canum Venaticorum (AM CVn), the ultrashort-period, hydrogen-deficient variable, are reported. An intense flare of (Delta m) peak roughly 0.34 was detected on February 24th, ...
  • Flares on AM Canum Venaticorum 
    Marar, T. M. K; Padmini, V. N; Seetha, S; Narayanan Kutty, K. R; Kasturirangan, K; Rao, U. R; Bhattacharyya, J. C (European Southern Observatory, 1988-01)
    AM CVn, an interacting binary system consisting of two helium white dwarfs, has been classified as a nova-like object. Normally it exhibits only small amplitude modulations of 0.05 mag with a 1051 s periodicity. The authors ...
  • High Speed Photometry of SS Cygni after an Outburst 
    Seetha, S; Padmini, V. N; Marar, T. M. K; Kasturirangan, K; Rao, U. R; Bhattacharyya, J. C (Konkoly Observatory, 1985-12)
  • High speed photometry of SS cygni after an outburst 
    Seetha, S; Padmini, V. N; Marar, T. M. K; Kasturirangan, K; Rao, U. R; Bhattacharyya, J. C (Konkoly Observatory, 1985-12-20)
  • 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 ...
  • Photometry of intermediate polars AO PSC and V 1223 SGR 
    Padmini, V. N; Marar, T. M. K; Seetha, S; Padmanabhan, P; Kasturirangan, K; Rao, U. R; Bhattacharyya, J. C; Kuppuswamy, K; Rozario, M. J (Springer, 1985-12)
    We present optical photometric observations of the cataclysmic variables AO Psc and V 1223 Sgr, both of which are believed to contain slowly-rotating white-dwarf pulsars. These objectes belong to the new class of intermediate ...
