    Meech, K. J; Pittichova, J; Yang, B; Zenn, A; Belton, M. J. S; A’Hearn, M. F; Bagnulo, S; Bai, J; Barrera, L; Bauer, J. M; Bedient, J; Bhatt, B. C; Boehnhardt, H; Brosch, N; Buie, M; Candia, P; Chen, W; Chesley, S; Chiang, P; Choi, Y; Cochran, A; Duddy, S; Farnham, T. L; Fernández, Y; Gutiérrez, P; Hainaut, O. R; Hampton, D; Herrmann, K; Hsieh, H; Kadooka, M. A; Kaluna, H; Keane, J; Kim, M; Kleyna, J; Krisciunas, K; Lauer, T. R; Lara, L; Licandro, J; Lowry, S. C; McFadden, L. A; Moskovitz, N; Mueller, B. E. A; Polishook, D; Raja, N. S; Riesen, T; Sahu, D. K; Samarasinha, N. H; Sarid, G; Sekiguchi, T; Sonnett, S; Suntzeff, N; Taylor, B; Tozzi, G. P; Vasundhara, R; Vincent, J; Wasserman, L; Webster-Schultz, B; Zhao, H (Elsevier B.V., 2011-05)
    We present observational data for Comet 9P/Tempel 1 taken from 1997 through 2010 in an international collaboration in support of the Deep Impact and Stardust-NExT missions. The data were obtained to characterize the nucleus ...
  • Mass function of open clusters NGC 1857 and Czernik 25 
    Sujatha, S; Babu, G. S. D; Ananthamurthy, S (Astronomical Society of India, 2006)
    The first CCD photometric UBVRI observations of the open clusters NGC 1857 (Czernik 20, OCl 427) and Czernik 25 (OCl 493) are presented. The observations were obtained on 28 November 2003 with the 2m Himalayan Chandra ...
  • Near-infrared JH photometry of young open cluster Be 59 
    Sharma, S; Ogura, K; Pandey, A. K; Ojha, D. K; Bhatt, B. C (Astronomical Society of India, 2007)
    We present near-infrared J H photometry and optical slitless spectroscopy of stars in the field of the young cluster Be 59. The J /(J- H )colour-magnitude diagram of the cluster yields a distance modulus of (m - M )0= 10.0 ...
  • NGC 1624 (OCl 403, Cr 53) – A very young open cluster 
    Sujatha, S; Babu, G. S. D (Springer, 2006)
    We present the first CCD photometric UBVRI observations of the not-so-well-studied open cluster NGC 1624 (OCl 403, Cr 53; α2000 = 04 h 40 m 36 s; δ2000 = + 50˚ 27′ 42″ Trumpler class = I 2 p N). This cluster was observed ...
  • Night Sky Extinction Measurements at the Indian Astronomical Observatory, Hanle 
    Parihar, P. S; Sahu, D. K; Bhatt, B. C; Subramaniam, A; Anupama, G. C; Prabhu, T. P (Astronomical Society of India, 2003)
    We present the estimates of the night sky extinction at the Indian Astronomical Observatory. Also presented are the estimates of the night sky brightness. The extinction in the U band at IAO is found to be lower than the ...
  • Optical observations of the bright long duration peculiar GRB 021004 afterglow. 
    Pandey, S. B; Sahu, D. K; Resmi, L; Sagar, R; Anupama, G. C; Bhattacharya, D; Mohan, V; Prabhu, T. P; Bhatt, B. C; Pandey, J. C; Parihar, P. S; Castro-Tirado, A. J (Astronomical Society of India, 2003)
    The CCD magnitudes in Johnson B,V and Cousins R and I photometric passbands are determined for the bright long duration GRB 021004 afterglow from 2002 October 4 to 16 starting ~ 3 hours after the γ - ray burst. Light curves ...
  • SN 2002ap, the Hypernova of Class Ic 
    Pandey, S. B; Sahu, D. K; Anupama, G. C; Bhattacharya, D; Sagar, R (Astronomical Society of India, 2003)
    The supernova SN 2002ap was discovered in the outer regions of the nearby spiral M74 on January 29.4 UT. Early photometric and spectroscopic observations indicate the supernova belongs to the class of Ic hypernova. Late ...
