    Chaubey, U. S (Astronomical Society of India, 1996)
    Spectrum scans of the eclipsing binary star RZ Cas at different phases in the wavelength range λλ 3300 - 7600 Amstrong taken through Hilger and Watts monochromator equipped with 104-cm telescope of Uttar Pradesh State ...
  • Survey for roAp stars in the northern sky from Naini Tal 
    Ashoka, B. N; Seetha, S; Raj, E; Chaubey, U. S; Gupta, S. K; Joshi, S; Martinez, P; Kurtz, D. W; Sagar, R; Kasturirangan, K (Astronomical Society of India, 2000)
    Of the 31 known rapidly oscillating Ap (roAp) stars, 28 are in the southern sky and majority of them were discovered at SAAO indicating that a systematic survey also is needed in the northern sky. Therefore, a project has ...
  • UBV photometry of comet Swift-Tuttle (1992t) 
    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 ...
  • UBV photometry of two eclipsing binary stars 
    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 ...
