  • TNO or Comet? The Search for Activity and Characterization of Distant Object 418993 (2009 MS9) 
    Bufanda, Erica; Meech, Karen J; Kleyna, Jan T; Hainaut, Olivier R; Bauer, James M; Stephens, Haynes; Veres, Peter; Micheli, Marco; Keane, Jacqueline V; Weryk, Robert; Wainscoat, Richard; Sahu, D. K; Bhatt, B. C (American Astronomical Society, 2023-01)
    The perihelion of the trans-Neptunian object (TNO) 2009 MS9 brings it close to the distance where some longperiod comets are seen to become active. Knowing this, and the fact that this object appears to brighten in excess ...
  • Triggered star formation and evolution of T-Tauri stars in and around bright-rimmed clouds 
    Chauhan, N; Pandey, A. K; Ogura, K; Ojha, D. K; Bhatt, B. C; Ghosh, S. K; Rawat, P. S (Blackwell Publishing, 2009-06)
    The aim of this paper is to quantitatively testify the `small-scale sequential star formation' hypothesis in and around bright-rimmed clouds (BRCs). As a continuation of the recent attempt by Ogura et al., we have carried ...
  • UBV CCD standards in two galactic directions-II 
    Mohan, V; Sanwal, B. B; Paliwal, D. C; Pandey, A. K; Bhatt, B. C; Robin, A. C (Astronomical Society of India, 1996)
  • UBV CCD standards near 5C1 radio sources at intermediate galactic latitude I 
    Mohan, V; Ojha, D. K; Bienayme, O; Paliwal, D. C; Pandey, A. K; Robin, A. L; Bhatt, B. C (Astronomical Society of India, 1994)
    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 ...
  • V1647 Orionis 
    Ojha, D. K; Ghosh, S. K; Kaurav, S. S; Bhatt, B. C; Sahu, D. K; Tej, A (International Astronomical Union, 2008-12)
  • V899 Mon: an outbursting protostar with a peculiar light curve, and its transition phases 
    Ninan, J. P; Ojha, D. K; Baug, T; Bhatt, B. C; Mohan, V; Ghosh, S. K; Menshchikov, A; Anupama, G. C; Tamura, M; Henning, Th (IOP Publishing, 2015-12-10)
    We present a detailed study of V899 Mon (a new member in the FUors/EXors family of young low-mass stars undergoing outburst), based on our long-term monitoring of the source starting from 2009 November to 2015 April. Our ...
  • Validation of estimated cloud fraction from MERRA-2 and AIRS data using ground based observation over IAO, Hanle 
    Shantikumar, S. N; Narendra, A; Bhatt, B. C; Prabhu, T. P; Anupama, G. C; Angchuk, D; Jorphail, S (Elsevier B.V, 2020-08-15)
    We report for validation of cloud fraction estimated from high-resolution (hourly) data from MERRA-2 and AIRS instrument aboard NASA’s Aqua satellite during its ascending and descending orbits with hourly ground-based ...
  • Young stellar population in the star-forming complex Sh2-252 
    Jose, J; Pandey, A. K; Ogura, K; Bhatt, B. C (Astronomical Society of India, 2012)
    We present the preliminary results of our multi-wavelength analyses of the young stellar population associated with the star forming complex Sh2-252. The NIR and MIR data sets from 2MASS and Spitzer-IRAC, MIPS identified ...
  • Young stellar population of bright-rimmed clouds BRC 5, BRC 7 and BRC 39 
    Panwar, N; Chen, W. P; Pandey, A. K; Samal, M. R; Ogura, K; Ojha, D. K; Jose, J; Bhatt, B. C (Oxford University Press on behalf of the Royal Astronomical Society, 2014-09-11)
    Bright-rimmed clouds (BRCs), illuminated and shaped by nearby OB stars, are potential sites of recent/ongoing star formation. Here we present an optical and infrared photometric study of three BRCs: BRC 5, BRC 7 and BRC ...
