  • 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 ...
  • Wind induced instabilities in accretion flow around black holes 
    Acharya, K; Chakrabarti, S. K; Molteni, D (Astronomical Society of India, 2002)
    We identify a new type of instability of the accrelation flow which is formed due to interaction of the outgoing winds with the incoming flow. Mainly due to shear instability, the flow oscillates around the equatorial ...
