    The scaling relations between the black hole (BH) mass and soft lag properties for both active galactic nuclei (AGNs) and BH X-ray binaries (BHXRBs) suggest the same underlying physical mechanism at work in accreting BH ...
  • Discovery of ubiquitous lithium production in low-mass stars 
    Bharat Kumar, Y; Reddy, B. E; Campbell, S. W; Maben, Sunayana; Zhao, G; Ting, Yuan-Sen (Springer Nature, 2020-11)
    The vast majority of stars with mass similar to that of the Sun are expected to destroy lithium (Li) gradually over the course of their lives, via low-temperature nuclear burning. This has now been supported by observations ...
  • Discrete space theory of radiative transfer 
    Peraiah, A (Cambridge University Press, 1984)
    A discrete space theory for radiative transfer based on invariant imbedding is described, along with applications. An interaction principle is defined for the relation between incident and emitted radiation from an optically ...
  • Discrete Space Theory of Radiative Transfer: Application 
    Srinivasa Rao, M (Springer, 2010)
    The method of obtaining the solution of radiative transfer equation using discrete space theory (DST) is described with (1) interaction principle for different geometries (2) star product (3) calculation of radiation field ...
  • Discrete Space Theory of Radiative Transfer: Applications 
    Srinivasa Rao, M (Astronomical Observatory, Volgina 7, 11160 Beograd, Serbia., 2009)
    A concise description of the method of obtaining the solution of radiative trans- fer equation which can be applied to di®erent geometrical and physical systems is given. This paper mainly deals with the steps for obtaining ...
  • Discretization of the equation of Radiative Transfer with Compton Scattering 
    Peraiah, A (Indian Institute of Astrophysics, Bangalore, 1986-05)
    We have attempted to solve the equation of radiative transfer by including Compton and inverse Compton scattering. We expanded the specific intensity by Taylor series at about v/sup1/ = v/sub0/. The resulting equation has ...

  • Disks around young stellar objects 
    Bhatt, H. C (Indian Academy of Science, 2011-07)
    By 1939, when Chandrasekhar’s classic monograph on the theory of Stellar Structure was published, although the need for recent star formation was fully acknowledged, no one had yet recognized an object that could be called ...
