  • A new three-band, two beam astronomical photo-polarimeter 
    Srinivasulu, G; Raveendran, A. V; Muneer, S; Mekkaden, M. V; Jayavel, N; Somashekar, M. R; Sagayanathan, K; Ramamoorthy, S; Rosario, M.; Jayakumar, K (Astronomical Society of India, 2014-09)
    We designed and built a new astronomical photo-polarimeter that can measure linear polarization simultaneously in three spectral bands. It has a Calcite beamdisplacement prism as the analyzer. The ordinary and extra-ordinary ...
  • Occultation of 2UCAC 42376428 by (423) Diotima on 2005 March 06 
    Vasundhara, R; Kuppuswamy, K; Ramamoorthy, S; Velu, C; Venkataramana, A. K (Astronomical Society of India, 2006-03)
    Observations of the occultation of the star 2UCAC 42376428 by (423) Diotima on 2005 March 06 at the Vainu Bappu Observatory are reported. The observed mid time of the event at 15:12:25.1 UT occurred 3.4 s later than the ...
  • A stellar photo-polarimeter 
    Raveendran, A. V; Srinivasulu, G; Muneer, S; Mekkaden, M. V; Jayavel, N; Somashekar, M. R; Sagayanathan, K; Ramamoorthy, S; Rosario, M. J; Jayakumar, K (Indian Institute of Astrophysics, 2015)
    A new astronomical photo-polarimeter that can measure linear polarization of point sources simultaneously in three spectral bands was designed and built in the Institute. The polarimeter has a Calcite beam-displacement ...
