  • Linear polarization in binaries with grey atmosphere I. Conservative Rayleigh scattering 
    Barman, S. K (Astronomical Society of India, 1999)
    This paper presents a method for calculating linear polarization from binaries whose surfaces are distorted due to tidal and rotational forces. The atmospheres in stars are grey, plane-parallel and pure scattering. The ...
  • Linear polarization of binaries II. Phase function : wQ~(µ)Q~' (µ') 
    Barman, S. K (Astronomical Society of India, 2000)
    This paper presents a method of calculating linear polarizations in close binaries whose surfaces are distorted due to tidal and rotational forces. Limb-darkening effect has been taken into account. Particles of different ...
  • Polarization in binaries 
    Barman, S. K; Peraiah, A (Astronomical Society of India, 1991)
    Theoretical models are computed for estimating linear polarization from the extended dusty outer layers of the components of a close binary system whose surfaces are distorted by rotation and mutual tidal effects. ...
  • Temperature and brightness distribution in the components of binary systems 
    Barman, S. K (Astronomical Society of India, 1993-03)
    From the theoretical model of a binary system for gravity darkening (Barman 1991), the temperature and brightness distributions along the surface of the components have been calculated using the third and fourth orders of ...
  • Temperature and brightness distributions in the components of close binary system 
    Barman, S. K (Astronomical Society of India, 1991)
    A theoretical model of close binary system for the gravity-darkening due to tidally and nonuniformly rotating Roche components has been formulated using the fourth order of r/R where r is the radial distance and R is the ...
