  • Evolution of the optical spectrum of SN 1987a in the Large Magellanic Cloud 
    Ashoka, B. N; Anupama, G. C; Prabhu, T. P; Giridhar, S; Ghosh, K. K; Jain, S. K; Pati, A. K; Kameswara Rao, N (Indian Academy of Sciences, 1987-06)
    The evolution of the spectrum of SN 1987a is traced from 1987 February 26 to March 31. Based on the low-resolution spectroscopic data the authors identify the lines of H, He I, Na I, Fe II, Sc II, Ca II which are known to ...
  • On the absolute magnitude of V482 Cygni, an R Coronae Borealis star 
    Kameswara Rao, N; Lambert, D. L (Astronomical Society of the Pacific, 1993-06)
    An identification of V482 Cygni, a R Coronae Borealis star, with a quadruple system containing a K5 III star is rejected. High-resolution spectra show that the radial velocity of V482 Cyg and the K5 III star differ by 35 ...
  • Photometric metallicity map of the large magellanic cloud 
    Choudhury, Samyaday; Subramaniam, A; Cole, A. A (Oxford University Press on behalf of the Royal Astronomical Society, 2016-01)
    We have estimated a metallicity map of the Large Magellanic Cloud (LMC) using the Mag- ellanic Cloud Photometric Survey (MCPS) and Optical Gravitational Lensing Experiment (OGLE III) photometric data. This is a first of ...
  • Star clusters in the magellanic clouds-1: parameterisation and classification of 1072 clusters in the LMC 
    Nayak, P. K; Subramaniam, A; Choudhury, S; Indu, G; Sagar, R (Oxford University Press on behalf of the Royal Astronomical Society, 2016-12-01)
    We have introduced a semi-automated quantitative method to estimate the age and reddening of 1072 star clusters in the Large Magellanic Cloud (LMC) using the Optical Gravitational Lensing Experiment III survey data. This ...
  • Star-clusters in the magellanic clouds and their mass functions 
    Sagar, R (Indian Academy of Sciences, 1993-03-10)
  • Study of candidate be stars in the magellanic clouds using near-infrared photometry and optical spectroscopy 
    Paul, K. T; Subramaniam, A; Mathew, B; Mennickent, R. E; Sabogal, B (Wiley-Blackwell, 2012-04)
    Mennickent et al. and Sabogal et al. identified a large number of classical Be (CBe) candidates (∼3500) in the Large and Small Magellanic Clouds (LMC and SMC) based on their photometric variability using the OGLE II data ...
  • The VMC survey – XIII. type II cepheids in the large magellanic cloud 
    Ripepi, V; Moretti, M. I; Marconi, M; Clementini, G; Cioni, M. -R. L; de Grijs, R; Emerson, J. P; Groenewegen, M. A. T; Ivanov, V. D; Muraveva, T; Piatti, A. E; Subramanian, S (Oxford University Press on behalf of the Royal Astronomical Society, 2015-01-21)
    The VISTA (Visible and Infrared Survey Telescope for Astronomy) survey of the Magellanic Clouds System (VMC) is collecting deep Ks-band time-series photometry of the pulsating variable stars hosted in the system formed by ...
  • The VMC survey – XIV. first results on the look-back time star formation rate tomography of the small magellanic cloud 
    Rubele, S; Girardi, L; Kerber, L; Cioni, Maria-Rosa. L; Piatti, A. E; Zaggia, S; Bekki, K; Bressan, A; Clementini, G; de Grijs, R; Emerson, J. P; Groenewegen, M. A. T; Ivanov, V. D; Marconi, M; Marigo, P; Moretti, Maria-Ida; Ripepi, V; Subramanian, S; Tatton, B. L; Van Loon, J. T (Oxford University Press on behalf of the Royal Astronomical Society, 2015-05-01)
    We analyse deep images from the VISTA survey of the Magellanic Clouds in the YJKs filters, covering 14 deg2 (10 tiles), split into 120 subregions, and comprising the main body and Wing of the Small Magellanic Cloud (SMC). ...
