  • Stellar and gas dynamical model for tidal disruption events in a quiescent galaxy 
    Mageshwaran, T; Mangalam, A (IOP Publishing, 2015-12-01)
    A detailed model of the tidal disruption events (TDEs) has been constructed using stellar dynamical and gas dynamical inputs that include black hole (BH) mass M•, specific orbital energy E and angular momentum J, star mass ...
  • Stellar and interstellar parameters from large photometric surveys 
    Malkov, O; Karpov, S; Kovaleva, D; Murthy, J; Sichevsky, S; Sytov, A; Zhao, G; Zhukov, A; Zakharo, A (NAS RA Byurakan Astrophysical Observatory, 2020-12)
    The parameterization of stars is a well known problem and used for various purposes in astronomy. We have shown that multicolor photometric data from large modern surveys can be used for parameterization of stars. With ...
  • Stellar astronomy with VBT 
    Kameswara Rao, N (Astronomical Society of India, 1993)
    The 2.34 meter Vainu Bappu Telescope (VBT) has been operating as a national facility for the last 3-4 years. Some of the current observational programs with VBT regarding the galactic astronomy are reviewed

  • Stellar Chromospheres 
    Bappu, M. K. V (1977)
  • Stellar chromospheres 
    Bappu, M. K. V (1969)
  • Stellar Content and Star Formation in Young Clusters Influenced by Massive Stars 
    Jose, J (American Astronomical Society, 2014-09)
    Star Formation (SF) in extreme environment is always challenging and can be significantly different from that in quiet environments. This study presents the comprehensive multi-wavelength (optical, NIR, MIR and radio) ...
  • Stellar contents and star formation in the young open cluster Stock 8 
    Jose, J; Pandey, A. K; Ojha, D. K; Ogura, K; Chen, W. P; Bhatt, B. C; Ghosh, S. K; Mito, H; Maheswar, G; Sharma, S (Blackwell Publishing, 2008-03)
    We present UBVIc CCD photometry of the young open cluster Stock 8 with the aim of studying its basic properties such as the amount of interstellar extinction, distance, age, stellar contents and initial mass function (IMF). ...
  • Stellar contents and star formation in the young star cluster Be 59 
    Pandey, A. K; Sharma, S; Ogura, K; Ojha, D. K; Chen, W. P; Bhatt, B. C; Ghosh, S. K (Blackwell Publishing, 2008-01)
    We present UBV Ic CCD photometry of the young open cluster Be 59 with the aim to study the star formation scenario in the cluster. The radial extent of the cluster is found to be ~10 arcmin (2.9 pc). The interstellar ...
  • Stellar contents of the open clusters Be 64 and Be 69 
    Pandey, A. K; Durgapal, A. K; Bhatt, B. C; Mohan, V; Mahra, H. S (EDP Sciences, 1997-04)
    We present UBVRI CCD photometry for previously unstudied open clusters (Be 64 and Be 69). Photometry has also been carried out for nearby fields to correct for the effects of field stars contamination. From the colour-colour ...
  • Stellar contents of two young open clusters: NGC 663 and 654 
    Pandey, A. K; Upadhyay, K; Ogura, K; Sagar, R; Mohan, V; Mito, H; Bhatt, H. C; Bhatt, B. C (Royal Astronomical Society, 2005-04)
    UBVRI CCD photometry in a wide field around two young open clusters, NGC 663 and 654, has been carried out. Hα and polarimetric observations for the cluster NGC 654 have also been obtained. We use the photometric data to ...
  • Stellar Disruption by Supermassive Black Holes and the Quasar Radio Loudness Dichotomy 
    Gopal-Krishna; Mangalam, A; Wiita, P. J (The American Astronomical Society, 2008-06-10)
    The origin of the dichotomy of radio loudness among quasars can be explained using recent findings that the mass of the central supermassive black hole (SMBH) in extended radio-loud quasars is systematically a few times ...
  • A stellar endgame - the born-again Sakurai's object 
    Asplund, M; Gustafsson, B; Lambert, D. L; Kameswara Rao, N (European Southern Observatory, 1997-05)
    The surface chemical composition of this remarkable star shows that it is hydrogen-deficient, carbon-rich and enriched in the light s-process elements. Spectra taken in May and October 1996 indicate a decrease in the surface ...
  • Stellar libraries as used in ISM modelling 
    Murthy, J (Astronomical Society of India, 2012)
    I present the use of stellar libraries in interstellar medium work. Stars are used as background sources against which interstellar absorption lines are observed and their modeling is necessary in order to set the baseline ...
  • Stellar multiplicities and signatures of supernova induced star formation in the Eta Carinae nebula 
    Rana, N. C; Gajria, B (Astronomical Society of India, 1994)
  • The stellar parametrization using Artificial Neural Network 
    Giridhar, S; Goswami, A; Kunder, A; Muneer, S; Selvakumar, G (Astronomical Society of India, 2012)
    An update on recent methods for automated stellar parametrization is given. We present preliminary results of the ongoing program for rapid parametrization of field stars using medium resolution spectra obtained using Vainu ...
  • Stellar populations in the magellanic clouds 
    Subramanian, S; Subramaniam, A (Astronomical Society of India, 2013)
    The structural parameters of the Large Magellanic Cloud and the Small Magellanic Cloud are derived from the study of di erent stellar populations, such as, Cepheids (age 100 Myr), Red Clump stars (age 2-9 Gyr) and RR ...
  • Stellar Populations in the Magellanic Clouds 
    Smitha, S (Indian Institute of Astrophysics, 2011-08)
    The Large Magellanic Cloud (LMC) and the Small Magellanic Cloud (SMC) are two nearby galaxies located at a distance of 50 kpc and 60 kpc respectively. The Magellanic Clouds (MCs) host young, intermediate-age and old ...
  • Stellar Relics from the Early Galaxy 
    Sivarani, T (Indian Academy of Sciences, 2013-03)
    We reviewed the recent progress in the field of stellar/galactic archeology, which is a study of the relics from the early galaxy. The oldest and most pristine objects that can be observed in the galaxy are the low mass ...
