    We have been doing a photometric and astrometric sample survey programme on Schmidt plates in a few selected directions in the Galaxy with an aim to study galactic stellar populations. In order to calibrate Schmidt plates ...
  • Kameswara Rao, N (D. Reidel Publishing Co., 1980-07)
    UBV observations obtained during the period 1972-73 are presented for the following five R CrB stars: GU Sgr, SU Tau, XX CAm, DZ And, V973 Oph, and the hydrogen-poor, carbon-rich stars BD + 10 deg 2179 and HD 137613. ...
  • Joshi, U. C; Sagar, R (Astronomical Society of Indian, 1986-06)
    UBV photometric observations of 135 stars near NGC 2539, obtained using the 104-cm Sampurnanand reflector at Uttar Pradesh State Observatory during 1975-1978, are reported. The data are presented in tables and graphs and ...
  • Padalia, T. D; Gupta, S. K; Srivastava, R. K; Chaubey, U. S (Astronomical Society of India, 1993)
    The comet Swift-Tuttle (1992t) was observed through UBV filters during twelve nights in December 1992. Magnitude variations of six circular zones from the center of the cometary head have been given. On the night of 17 ...

  • Radhakrishnan, K. R; Sarma, M. B. K; Abhyankar, K. D (Astronomical Society of India, 1985-09)
  • Chaubey, U. S; Singh, Mahendra (Astronomical Society of India, 1984-03)
    UBV light curves of the eclipsing binary systems V364 Cas and MM Cas are presented. A total of eight photoelectric times of minimum light for these stars were derived. The UBV photometric data of V364 Cas show that the ...
  • Mekkaden, M. V; Raveendran, A. V (The European Southern Observatory, 1998-10)
    We present UBVRI and uvby photometry of HD 81410 obtained on a total of 40 nights during 1987-90, and an analysis of its long-term photometric behaviour. The star is found to show two well-separated minima in its light ...
  • Kameswara Rao, N; Raveendran, A. V (European Southern Observatory, 1993-07)
    We present UBVR polarimetry V 854 Cen obtained on four nights during February 1991-March 1992. Two sets of measurements are close to two nearby light maxima and the other two during the declines when the star was around 4 ...
  • Sujatha, S; Babu, G. S. D; Ananthamurthy, S (Astronomical Society of India, 2004-12)
    CCD photometric observations of three open clusters Berkeley 15 (=OCl 414), Czernik 18 (=OCl 426) and NGC 2401 (=OCl 588), obtained for the first time in UBVRI filters down to V=20 mag, are presented here. They are located ...
  • Yadav, R. K. S; Sagar, R (Astronomical Society of India, 2003)
    We report the first deep $UBVRI$ CCD photometry of 2460 stars in the field of two poorly studied OB associations Bochum 1 and Bochum 6. We selected 15 and 14 probable members in Bochum 1 and Bochum 6 respectively using ...
  • Sagar, R; Cannon, R. D (Astronomical Society of India, 1994)
  • Parthasarathy, M; Jain, S. K (International Astronomical Union, 1993)
  • Bhattacharjee, P (Indian Academy of Sciences, 2000-08)
    The observed cosmic ray events above 10/Sup11 GeV are difficult to explain within the context of known physics of propagation of known particles in the Universe and within the standard acceleration mechanisms that are ...
  • Chakraborty, A; Anandarao, B. G; Swaminathan, R (Astronomical Society of India, 1993)
    We present here preliminary results of observations on two Be stars gamma Cas and lambda Eri made during 27-30 December 1992 and 14-15 February 1993.
