  • Planetary nebulae with UVIT II. Revelations from far-UV vision of Butterfly nebula NGC 6302 
    Kameswara Rao, N; De Marco, O; Sriram, K; Murthy, J; Ray, A; Sutaria, F. K; Mohan, Rekhesh (EDP Sciences, 2018-12)
    The high excitation planetary nebula, NGC 6302, has been imaged in two far-ultraviolet (FUV) filters, F169M (Sapphire; λeff: 1608 Å)and F172M (Silica; λeff: 1717 Å) and two near-UV (NUV) filters, N219M (B15; λeff: 2196 Å) ...
  • Planetary nebulae with UVIT: A progress report 
    Kameswara Rao, N; Sutaria, F; Murthy, J; Ray, A; Pandey, G (Indian Academy of Sciences, 2021-10)
    The spectral region between 1250–3000 A contains important spectral lines to understand the ˚ morphological structures and evolution of planetary nebulae. This is the region sampled by UVIT through various filter bands ...
  • Studies of a possible new Herbig Ae/Be star in the open cluster NGC 7380 
    Mathew, B; Banerjee, D. P. K; Ashok, N. M; Subramaniam, A; Bhavya, B; Joshi, V (Chinese Academy of Sciences, 2012-02)
    We present a study of the star 2MASS J22472238+5801214 with the aim of identifying its true nature which has hitherto been uncertain. This object, which is a member of the young cluster NGC 7380, has been variously proposed ...
  • TW Hya: Spectral Variability, X-Rays, and Accretion Diagnostics 
    Dupree, A. K; Brickhouse, N. S; Cranmer, S. R; Luna, G. J. M; Schneider, E. E; Bessell, M. S; Bonanos, A; Crause, L. A; Lawson, W. A; Mallik, S. V; Schuler, S. C (IOP Publishing, 2012-05-01)
    The nearest accreting T Tauri star, TW Hya was intensively and continuously observed over ~17 days with spectroscopic and photometric measurements from four continents simultaneous with a long segmented exposure using the ...
  • V899 Mon: an outbursting protostar with a peculiar light curve, and its transition phases 
    Ninan, J. P; Ojha, D. K; Baug, T; Bhatt, B. C; Mohan, V; Ghosh, S. K; Menshchikov, A; Anupama, G. C; Tamura, M; Henning, Th (IOP Publishing, 2015-12-10)
    We present a detailed study of V899 Mon (a new member in the FUors/EXors family of young low-mass stars undergoing outburst), based on our long-term monitoring of the source starting from 2009 November to 2015 April. Our ...
  • VLTI-AMBER velocity-resolved aperture-synthesis imaging of η· Carinae with a spectral resolution of 12 000 
    Weigelt, G; Hofmann, K. H; Schertl, D; Clementel, N; Corcoran, M. F; Damineli, A; De Wit, W. J; Grellmann, R; Groh, J; Guieu, S; Gull, T; Heininger, M; Hillier, D. J; Hummel, C. A; Kraus, S; Madura, T; Mehner, A; Merand, A; Millour, F; Moffat, A. F. J; Ohnaka, K; Patru, F; Petrov, R. G; Sridharan, R; Richardson, N. D; Rivinius, T; Scholler, M; Teodoro, M; Wittkowski, M (EDP Sciences, 2016-10)
    Context. The mass loss from massive stars is not understood well. η Carinae is a unique object for studying the massive stellar wind during the luminous blue variable phase. It is also an eccentric binary with a period of ...
