  • Detection of solar-like oscillations from Kepler photometry of the open cluster NGC 6819 
    Stello, D; Basu, S; Bruntt, H; Mosser, B; Stevens, I. R; Brown, T. M; Christensen-Dalsgaard, J; Gilliland, R. L; Kjeldsen, H; Arentoft, T; Ballot, J; Barban, C; Bedding, T. R; Chaplin, W. J; Elsworth, Y. P; Garcia, R. A; Goupil, M. J; Hekker, S; Huber, D; Mathur, S; Meibom, S; Samadi, R; Sangaralingam, V; Baldner, C. S; Belkacem, K; Biazzo, K; Brogaard, K; Suarez, J. C; D'Antona, F; Demarque, P; Esch, L; Gai, N; Grundah, F; Lebreton, Y; Jiang, B; Jevtic, N; Karoff, C; Miglio, A; Molenda-Zakowicz, J; Montalban, J; Noels, A; Roca Cortes, T; Roxburgh, I. W; Serenelli, A. M; Silva, V; Christiaan Sterken, A; Stine, P; Szabo, R; Weiss, A; Borucki, W. J; Koch, D; Jenkins, J. M (Institute of Physics, 2010-04)
    Asteroseismology of stars in clusters has been a long-sought goal because the assumption of a common age, distance and initial chemical composition allows strong tests of the theory of stellar evolution. We report results ...
  • First Results from the NOAO Survey of the Outer Limits of the Magellanic Clouds 
    Saha, A; Olszewski, E. W; Brondel, B; Olsen, K; Knezek, P; Harris, J; Smith, C; Subramaniam, A; Claver, J; Rest, A; Seitzer, P; Cook, K. H; Minniti, D; Suntzeff, N. B (IOP Publishing, 2010-12)
    We describe the first results from the Outer Limits Survey, an NOAO survey designed to detect, map, and characterize the extended structure of the Large and Small Magellanic Clouds (LMC and SMC). The survey consists of ...
  • A flattening in the optical light curve of SN 2002ap 
    Pandey, S. B; Anupama, G. C; Sagar, R; Bhattacharya, D; Sahu, D. K; Pandey, J. C (Royal Astronomical Society, 2003-04)
    We present the UBVRcIc broad-band optical photometry of the Type Ic supernova SN 2002ap obtained during 2002 February 6-March 23 in the early decline phases and also later on 2002 August 15. Combining these data with the ...
  • The optical afterglow of the not so dark GRB 021211 
    Pandey, S. B; Anupama, G. C; Sagar, R; Bhattacharya, D; Castro-Tirado, A. J; Sahu, D. K; Parihar, P. S; Prabhu, T. P (The European Southern Observatory, 2003-09)
    We determine Johnson B,V and Cousins R,I photometric CCD magnitudes for the afterglow of GRB 021211 during the first night after the GRB trigger. The afterglow was very faint and would have been probably missed if no prompt ...
  • Star formation in young cluster NGC 1893 
    Sharma, S; Pandey, A. K; Ojha, D. K; Chen, W. P; Ghosh, S. K; Bhatt, B. C; Maheswar, G; Sagar, R (International Astronomical Union, 2008-05)
    We have carried out a multi-wavelength study of the star forming region NGC 1893 to make a comprehensive exploration of the effects of massive stars on low mass star formation. Using deep optical U BV RI broad band, Hα ...
