  • Studies of Pulsating Carbon Stars 
    Raveendran, A. V (Indian Institute of Astrophysics, Bangalore, 1989-10)
  • Study of Hot Post-AGB Stars 
    Geetanjali Gauba (Indian Institute of Astrophysics, Bangalore, 2003-08)
  • Transition probability parameters for certain band systems of astrophysical molecule GeO 
    Rajamanickam, N; Shanmugavel, R; Prithivikumaran, N; Palaniselvam, T; Bagare, S. P (Elsevier Science B.V., 2003-05)
    The transition probability parameters, Franck-Condon factors and /r-centroids, have been evaluated using the most reliable numerical integration procedure for the bands of E1Σ+, F1Σ+, /GΣ, HΠ, JΣ-X1Σ+ systems of astrophysical ...
  • Understanding the behavior of energy X-rays from the black hole candidate GRS 1915+105 
    Nandi, A; Chakrabarti, S. K (Astronomical Society of India, 2002)
    Black Hole candidate GRS 1915+105 shows a very interesting behaviour at high energy X-rays. For instance, it shows quasi-Periodic Oscillations (QPO) only at high energies. Also the spectral slopes at high energies vary and ...
  • Understanding the Radio Emission Geometry of Multiple-Component Radio Pulsars from Retardation and Aberration Effects 
    Gupta, Y; Gangadhara, R. T (The American Astronomical Society, 2003-02)
    We have conducted a detailed analysis of the emission geometry of a handful of radio pulsars that have prominent, multiple-component profiles at meter wavelengths. From careful determination of the total number of emission ...
  • Upcoming Indian facility: UVIT on ASTROSAT 
    Subramaniam, A (Astronomical Society of India, 2012)
    An overview of the upcoming ASTROSAT mission with its five instruments on board is presented. UVIT instrument is discussed in detail along with the ground calibrations and plans for in-orbit calibrations. The UVIT filter ...
  • UV observations of globular clusters and nearby galaxies 
    Subramaniam, A (Astronomical Society of India, 2007-06)
    We propose to identify the hot stellar population of the galactic globular clusters (GCs) using the TAUVEX. These stars can be easily identified in the core of the GCs where the crowding due to the main-sequence stars get ...
  • What the Stars tell... 
    Sivaram, C (Deccan Herald, 2009-01-06)
  • Window-threshold technique for detecting pulse components 
    Gangadhara, R. T (Astronomical Society of India, 2000)
    We have analysed high-quality single pulse data of PSR B0329+54 at 606 MHz to study the structure of the emission beam. In order to unambiguously detect weak emission components in the integrated pulse profile, we have ...
  • Young stellar objects and their environment 
    Choudhury, R (Astronomical Society of India, 2012)
    This paper presents the results of a Ph.D thesis emphasizing the studies of various characteristics of Young Stellar Objects (YSOs) and their environment. The main objective of the thesis is to study the effects of mechanical ...
