  • The thickness of accretion α-disks: Theory and observations 
    Suleimanov V.; Lipunova G.; Shakura N. (2007)
    Observations of X-ray binaries indicate substantial half-thicknesses for the accretion disks in these systems (up to h/R ≈ 0.25, where h is the disk half-thickness and R its radius), while standard α accretion disks predict ...
  • Long-period variations of pulsar emission and the dynamical ellipticity of neutron stars 
    Kitiashvili I.; Gusev A. (2008)
