  • CCD imaging of Jupiter during its impact with Comet Shoemaker-Levy 9 : Observations from Jaisalmer 
    Tej, A; Chandrasekhar, T; Ashok, N. M; Ragland, S; Mathur, S. N; Jain, J (Astronomical Society of India, 1996)
    CCD imaging observations of Jupiter were carried out, from the desert location of Jaisalmer in Rajasthan, during the period of its collision with the comet Shoemaker-Levy 9. A Celestron 8 telescope was used with a Lynx PC ...

K; Kumar, H; Bhalerao, V; Anupama, G. C; Barway, Sudhanshu; Brandeker, A; Floren, H. G; Olofsson, G; Bruno, G; Mao, Y. M; Ye, R. H; Zou, Q. Y; Sun, Y. K; Shen, Y. Y; Zhao, J. Y; Grishin, D. N; Romanova, L. V; Marchis, F; Fukui, K; Kukita, R; Benedetti-Rossi, G; Santos-Sanz, P; Dhyani, N; Gokhale, A; Kate, A (EDP Sciences, 2024-02)
    Context. In about 2000, the south pole of Triton experienced an extreme summer solstice that occurs every ∼650 years, when the subsolar latitude reached about 50°S. Bracketing this epoch, a few occultations probed the ...
  • Interpretation of angular diameter measurements of Mira variables: role of water 
    Tej, A; Lancon, A; Scholz, M (Astronomical Society of India, 2005-06)
    For stars with atmospheres as complex as those of Miras, determination of fundamental stellar parameters remains a challenge. Occurrence of water "shells" and their implication on the interpretation of the angular diameter ...
  • A multiwavelength study of the massive star-forming region IRAS 06055+2039 (RAFGL 5179) 
    Tej, A; Ojha, D. K; Ghosh, S. K; Kulkarni, V. K; Verma, R. P; Vig, S; Prabhu, T. P (EDP Sciences, 2006-06)
    Aims.We present a multiwavelength study of the massive star-forming region associated with IRAS 06055+2039. Methods.Narrow-band near-infrared (NIR) observations were carried out with UKIRT-UFTI in molecular hydrogen and ...
  • The outburst and nature of young eruptive low mass stars in dark clouds 
    Ninan, J. P; Ojha, D. K; Bhatt, B. C; Mallick, K. K; Tej, A; Sahu, D. K; Ghosh, S. K; Mohan, V (Astronomical Society of India, 2012)
    The FU Orionis (FUor) or EX Orionis (EXor) phenomenon has attracted increasing attention in recent years and is now accepted as a crucial element in the early evolution of low-mass stars. FUor and EXor eruptions of young ...
  • Post-outburst phase of LDN 1415 nebula (IRAS 04376+5413) 
    Pawad, V. S; Ojha, D. K; Ninan, J. P; Tej, A; Bhatt, B. C; Sahu, D. K; Ghosh, S. K; Kaurav, S. S; Mohan, V (Astronomical Society of India, 2010)
    LDN 1415 nebula was first detected by Stecklum (2006) in early April 2006 in the vicinity of lRAS 04376+5413. In this paper, we present a study of the post-outburst phase of LDN 1415 nebula using optical (V, R, J) and ...
  • Post-outburst phase of McNeil's nebula (V1647 Orionis) 
    Ojha, D. K; Ghosh, S. K; Tej, A; Verma, R. P; Vig, S; Anupama, G. C; Sahu, D. K; Parihar, P. S; Bhatt, B. C; Prabhu, T. P; Maheswar, G; Bhatt, H. C; Anandarao, B. G; Venkataraman, V (Blackwell Publishing, 2006-03)
    We present a detailed study of the post-outburst phase of McNeil's nebula (V1647 Orionis) using optical B, V, R, I and near-infrared (NIR) J, H, K photometric and low-resolution optical spectroscopic observations. The ...
  • Second outburst phase of McNeil's nebula (V1647 Orionis) 
    Kaurav, S. S; Ojha, D. K; Ninan, J. P; Bhatt, B. C; Sahu, D. K; Ghosh, S. K; Tej, A (Astronomical Society of India, 2010)
    The FU Ori/EX Od phenomenon represents a rare and not yet fully understood phase of the early evolution of low mass stars. Therefore, the photometric and spectroscopic monitoring of the post-outburst phase of these ...
  • V1647 Orionis 
    Ojha, D. K; Ghosh, S. K; Kaurav, S. S; Bhatt, B. C; Sahu, D. K; Tej, A (International Astronomical Union, 2008-12)
