  • Ridsdale, A. C (Astronomical Society of India, 1916)
  • Parthasarathy, M (Astronomical Society of India, 1990)
    The abundances and mass loss aspects of close binary systems are discussed. Emphasis is given to Algol systems, including V453 Sco, V 356 Sgr, RY Scuti, and W Serpentis. Hydrogen-poor close binary systems, symbiotic stars, ...
  • Chaubey, U. S (Astronomical Society of India, 1998)
  • Sharma, Ekta; Maheswar, G; Dib, S (EDP Sciences, 2022-02)
    Context. The Cepheus Flare region consists of a group of dark cloud complexes that are currently active in star formation. Aims. The aim of this work is to estimate the motions of four clouds, namely L1147/1158, L1172/1174, ...
  • Sengupta, S (IOP Science, 2008-08)
    The peak amplitude of linear polarization detected recently from an extraso- lar hot giant planet HD 189733b, is a few times of 10−4 , more than an order of magnitude higher than all theoretical predictions. Rayleigh ...
  • Issac, Namitha; Saha, Anindya; Choudhary, Saanika; Chaudhary, Aakash; Tej, Anandmayee; Liu, Hong-Li; Liu, Tie; Maheswar, G (American Astronomical Society, 2024-04-01)
    We present a detailed structural and gas kinematic study of the star-forming complex W5-NW. A cloud–cloud collision scenario unravels with evidence of collision-induced star and cluster formation. Various signatures of ...
  • Singh, J (Springer, 1985-02)
    The line and continuum intensities deduced from the multislit spectra of the (Fe X) coronal emission line taken at the 1980 eclipse are used to discuss the relative roles of radiative and collisional-excitation mechanisms. ...
  • Subramaniam, A (EDP Sciences, 2004-10)
    The stellar population and star clusters around six regions in the Large Magellanic Cloud (LMC) are studied to understand the correlation between star formation and cluster formation rates. We used the stellar data base ...
  • Krishan, V; Sivaram, C (Royal Astronomical Society, 1991-05)
    A definite physical mechanism based in inverse cascading is suggested which quite naturally yields a bottom-up hierarchical structure for galactic clustering. In this mechanism, nonlinear interactions between small fluid ...
  • Krishan, V (Royal Astronomical Society, 1993-09-01)
    The development of large-scale flows from the stresses generated by small-scale flows in a Navier-Stokes system is studied in order to model the large-scale structure of the Universe. This process is an analogue of the ...
  • Arun, R; Mathew, B; Maheswar, G; Baug, Tapas; Kartha, S. S; Selvakumar, G; Manoj, P; Shridharan, B; Anusha, R; Narang, Mayank (Oxford University Press on behalf of the Royal Astronomical Society, 2021-10)
    We study the formation and the kinematic evolution of the early-type Herbig Be star IL Cep and its environment. The young star is a member of the Cep OB3 association, at a distance of 798 ± 9 pc, and has a ‘cavity’ ...
  • Suryanarayana, G. S; Balakrishna, K. M (Elsevier B.V, 2018-05-01)
    It is often noticed that the occurrence rate of Coronal Mass Ejections (CMEs) increases with increase in flare duration where peak flux too increase. However, there is no complete association between the duration and peak ...
  • Anathpindika, S (Elsevier B.V., 2011-12)
    In the present work we examined the hypothesis that, a core mass function (CMF), such as the one deduced for cores in the Orion molecular cloud (OMC), could possibly be the primogenitor of the stellar initial mass function ...
  • Bhatt, H. C (European Southern Observatory, 1989-04)
    Polarization measurements of Cn 1-1 are interpreted as due to scattering by nebular dust. It is suggested that the nebula has a bipolar morphology. This, together with the enhanced nitrogen abundance in the nebula, supports ...
  • Bhatt, H. C; Mallik, D. C. V (The European Southern Observatory, 1986-11)
    Cn 1-1 is an emission-line object that shows strong emission lines characteristic of high density planetary nebulae superposed on the stellar spectrum of an F5 III-IV star. The authors estimate the absolute luminosity of ...
  • Rautela, B. S; Joshi, G. C; Srivastava, J. B (Astronomical Society of India, 1998)
  • Sanwal, B. B; Singh, M (Astronomical Society of India, 1999)
    The spectrophotometric observations of the Comet C/1995 O1 Hale-Bopp were taken through 104 cm telescope of the U.P. State Observatory, Naini Tal using EG & G Spectrograph coupled with an Optical Multi Channel Analyser and ...
  • Murty, P. S (D.Reidel Publishing Co.,, 1982-02)
    New identifications are reported of the fourth positive bands and Cameron bands of CO in the IUE satellite spectrum of Comet Bradfield (1979l). Although the predicted band intensities as well as the band identifications ...
  • Kim, G; Lee, C.W; Maheswar, G; Kim, Mi-Ryang; Archana Soam; Saito, Masao; Kiyokane, Kazuhiro; Kim, Sungeun (IOP Publishing, 2019-02)
    We present the results of a systematic search for molecular outflows in 68 Very Low Luminosity Objects (VeLLOs) from single-dish observations in CO isotopologues, finding 16 VeLLOs that show clear outflow signatures in the ...
