    Shantikumar, N. S; Khatri, Pradeep; Larson, E. J. L; Dumka, Umesh Chandra; Sarangi, Chandan; Vineeth, R (Elsevier B.V., 2023-02-01)
    Biomass burning emits a large quantity of gaseous pollutants and aerosols into the atmosphere, which perturbs the regional and global climate and has significant impacts on air quality and human health. In order to understand ...
  • Classification of Nova Spectra 
    Anupama, G. C (Astronomical Society of India, 2012)
    The evolution of the optical spectrum of a nova outburst is described. The classification schemes used to classify novae based on the outburst spectral features and their evolution are discussed.

    Gulati, R. K; Gupta, R; Gothoskar, P; Khobragade, S (Astronomical Society of India, 1996)
    Scheme based on the artificial neural networks (ANNs) trained with multi-layer back propagation using single level network for classifying ultraviolet spectra in the IUE Low-Dispersion Spectra Reference Atlas is presented. ...
  • A classification scheme for pulsars 
    Kochhar, R. K (Nature Publishing Group, 1977-11)
    The implications of a pulsar classification scheme are discussed. Three types of pulsars are distinguished - Type S (S for single) from supernova explosions of single stars; type D (D for disrupted) from binaries disrupted ...
  • The climate of Madras and environs 
    Narayan, B. G (Indian Academy of Sciences, 1938)

  • Close binaries - Abundances and mass loss 
    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, ...
  • Close binary stars with moderate size optical telescope 
    Chaubey, U. S (Astronomical Society of India, 1998)
  • Cloud motion and magnetic fields: Four clouds in the Cepheus Flare region 
    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, ...
  • Cloudy atmosphere of the extra-solar planet HD189733b: A possible explanation of the detected B-band polarization 
    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 ...
  • Cloud–Cloud Collision and Cluster Formation in the W5-NW Complex 
    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 ...
  • Clues to the mode of excitation of Fe X ions in the solar corona from the 1980 eclipse observations 
    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. ...
  • Cluster formation versus star formation rates around six regions in the Large Magellanic Cloud 
    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 ...
  • Clustering of galaxies by inverse cascade in a turbulent medium 
    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 ...
  • Clustering of Galaxies by the Alpha-Effect 
    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 ...
  • Clustering of low-mass stars around Herbig Be star IL Cep – evidence of ‘Rocket Effect’ using Gaia EDR3 ? 
    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’ ...
  • CME productivity associated with Solar Flare peak X-ray emission flux 
    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 ...
  • CMEs evolve in the interplanetary medium to double their predicted geo-effectiveness

    We explore the impact of interactions between coronal mass ejections (CMEs) – known as CME–CME interactions – on Earth using remote-sensing and in situ observations and estimate the amplification of the geo-effectiveness ...
  • The CMF as provenance of the stellar IMF? 
    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 ...
  • CN 1-1 - A bipolar type I planetary nebula 
    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 ...
