  • Unveiling Vela: time variability of interstellar lines in the direction of the Vela supernova remnant – II. Na D and Ca II 
    Kameswara Rao, N; Lambert, D. L; Reddy, A. B. S; Gupta, R; Muneer, S; Singh, H. P (IOP Publishing, 2017-05)
    In a survey conducted between 2011 and 2012 of interstellar Na I D line profiles in the direction of the Vela supernova remnant (SNR), a few lines of sight showed dramatic changes in low-velocity absorption components with ...
  • UOCS-IX. AstroSat/UVIT Study of the Open Cluster NGC 2818: Blue Stragglers, Yellow Stragglers, Planetary Nebula, and their Membership 
    Sharmila Rani; Pandey, G; Subramaniam, A; Kameswara Rao, N (American Astronomical Society, 2023-03-01)
    We present the first far-UV (FUV) imaging results of the intermediate-age Galactic open cluster NGC 2818 that has a planetary nebula (PN) within the field using images taken from the Ultra Violet Imaging Telescope ...
  • UV astronomy and stellar chromosphere 
    Kameswara Rao, N (Saha Institute of Nuclear Physics, 1995)
    "The abrupt termination of solar and stellar spectrum below A 2900 has been a great handicap to the advancement of our knowledge of the heavenly bodies ; because the ...
  • UV imaging telescope for the Indian Multiwavelength Astronomy Satellite 
    Pati, A. K; Kameswara Rao, N (SPIE-The International Society for Optical Engineering, 1998-08)
    The UV Imaging Telescope is a part of the proposed Indian Multiwavelength Astronomy Satellite mission. The initiate for an astronomy mission has ben taken by several institution in India, after the successful demonstration ...
  • The UV spectrum of the WC 11 star CPD -56 deg 8032 
    Kameswara Rao, N; Giridhar, S; Nandy, K (The European Southern Observatory, 1990-08)
    UV observations of the WC 11 central star of the compact planetary nebula CPD -56 deg 8032 show that the continuum flux is variable. This variability appears to be caused by a change in the circumstellar extinction properties. ...
  • UVIT–HST–GAIA view of NGC 288: a census of the hot stellar population and its properties from UV 
    Snehalata Sahu; Subramaniam, A; Cote, Patrick; Kameswara Rao, N; Stetson, Peter B (Oxford University Press on behalf of the Royal Astronomical Society, 2019-01)
    A complete census of the blue horizontal branch (BHB) and blue straggler star (BSS) population within a 10 radius from the centre of the globular cluster NGC 288 is presented, based on images from the Ultraviolet Imaging ...
  • A "variable" stellar object in a variable blue nebula V-V 1-7 
    Kameswara Rao, N; Gilra, D. P (The Observatory, 1981-08)
  • Variation of linear polarization in the R Aquarii system 
    Deshpande, M. R; Joshi, U. C; Kulshrestha, A. K; Sen, A. K; Kameswara Rao, N; Raveendran, A. V (Astronomical Society of the Pacific, 1987-01)
    Linear polarization measurements of the R Aqr system are reported here. The R Aqr system shows strong wavelength dependence of percent polarization and position angle, which are strongly time dependent also. There is a ...
  • VLA observations of extreme hydrogen deficient stars 
    Kameswara Rao, N; Venugopal, V. R; Patnaik, A (Indian Academy of Sciences, 1985-09)
    Observations at 2 and 6 cm have been obtained for six hydrogen-deficient stars R CrB, HD 160641, BD -9 deg 4395, V 348 Sgr, MV Sgr, and Upsilon Sgr by means of the National Radio Astronomy Observatory's Very Large Array ...
  • XX Cam -The Inactive R CrB Star 
    Kameswara Rao, N; Ashok, N. M; Kulkarni, P. V (Indian Academy of Sciences, 1980-09)
    Infrared observations obtained six years apart of the R CrB type star XX Cam do not show any infrared excess, unlike all other members of the class. The observed colours match a 7000 K black body energy distribution quite ...
