  • Activity of the first interstellar comet 2I/Borisov around perihelion: results from Indian observatories 
    Aravind, K; Ganesh, Shashikiran; Venkataramani, Kumar; Sahu, D. K; Angchuk, D; Sivarani, T; Unni, Athira (Oxford University Press on behalf of the Royal Astronomical Society, 2021-04)
    Comet 2I/Borisov is the first true interstellar comet discovered. Here, we present results from observational programs at two Indian observatories, 2 m Himalayan Chandra Telescope at the Indian Astronomical Observatory, ...

    Hsieh, H. H; Yang, Bin; Haghighipour, N; Kaluna, H. M; Fitzsimmons, A; Denneau, L; Novakovic, B; Jedicke, R; Wainscoat, R. J; Armstrong, J. D; Duddy, S. R; Lowry, S. C; Trujillo, C. A; Micheli, M; Keane, J. V; Urban, L; Riesen, T; Meech, K. J; Abe, S; Cheng, Yu-Chi; Chen, Wen-Ping; Granvik, M; Grav, T; Ip, Wing-Huen; Kinoshita, D; Kleyna, J; Lacerda, P; Lister, T; Milani, A; Tholen, D. J; Vereš, P; Lisse, C. M; Kelley, M. S; Fernández, Y. R; Bhatt, B. C; Sahu, D. K; Kaiser, N; Chambers, K. C; Hodapp, K. W; Magnier, E. A; Price, P. A; Tonry, J. L (IOP Publishing, 2012-03-20)
    The main-belt asteroid (300163) 2006 VW139 (later designated P/2006 VW139) was discovered to exhibit comet-like activity by the Pan-STARRS1 (PS1) survey telescope using automated point-spread-function analyses performed ...
  • Optical spectroscopy of comets using Hanle Echelle Spectrograph (HESP) 
    Aravind, K; Venkataramani, Kumar; Ganesh, Shashikiran; Surya, Arun; Sivarani, T; Sahu, D. K; Unni, Athira; Bhardwaj, Anil (Oxford University Press on behalf of Royal Astronomical Society, 2024-05)
    Observing the vibrational/rotational lines in a comet’s optical spectrum requires high-resolution spectroscopy, as they are otherwise seen as a blended feature. To achieve this, we have obtained medium and high-resolution ...
  • Outgassing Behavior of C/2012 S1 (ISON) from 2011 September to 2013 June 
    Meech, K. J; Yang, B; Kleyna, J; Ansdell, M; Chiang, H. F; Hainaut, O; Vincent, J. B; Boehnhardt, H; Fitzsimmons, A; Rector, T; Riesen, T; Keane, J. V; Reipurth, B; Hsieh, H.

K; Lisse, C; Denneau, L; Jedicke, R; Magnier, E; Wainscoat, R (IOP Publishing, 2013-10-20)
    We report photometric observations for comet C/2012 S1 (ISON) obtained during the time period immediately after discovery (r = 6.28 AU) until it moved into solar conjunction in mid-2013 June using the UH2.2 m, and Gemini ...
