  • Freddi : the code / by K. Malanchev to compute FRED-like light curves of LMXB calculate evolution of the accretion disk with time-independent viscosity in a binary system
    The code solves 1-D evolution equation of Shakura-Sunyaev accretion disk. The code is developed to simulate fast rise exponential decay (FRED) light curves of low mass X-ray binaries (LMXBs) and is briefly described in “Determination of the turbulent parameter in the accretion disks: effects of self-irradiation in 4U 1543-47 during the 2002 outburst” by Lipunova & Malanchev (2016)
  • C-code to calculate evolution of the accretion disk with time-independent viscosity in a binary system (v0.3 March 2015) ( см. ApJ 2015 ).
  • Multi-color black body disk dimensionless spectrum for values: Fnu/Fmax vs. x = h nu/ kTmax, where Tmax - maximum temperature of Shakura-Sunyaev disk table - plot
  • Angular dependence Psi(theta) of intensity from accretion disk in Kerr-metric. Observed flux F=L*Psi(theta)/(4 pi D)^2, where L is the bolometric luminosity, D is the distance to the disk, theta is the angle between the normal to the disk plane and the line of sight, mu = cos(theta), mu=0 when photons go parallel to the disk plane. a=0.0 ; a=0.9981 ; Functions are calculated using different codes: kerrbb (Li et al., 2005), Laor-Netzer (1990), and Speith et al. (1995). Cumulative "INT"-curves are integrated over the angle. ( см. AЖ 2007 ).
