Mass ejection from disks surrounding a low-mass black hole: Viscous neutrino-radiation hydrodynamics simulation in full general relativity

Rest-mass density in units of g=cm<sup>3</sup>, temperature (kT) in units of MeV, specific entropy per baryon in units of k, and electron fraction Y<sub>e</sub> for model K8. The rest-mass density, the value of Y<sub>e</sub>, and the temperature of the  atmosphere artificially added are ≈10 g=cm<sup>3</sup>, 0.5, and ≈0.036 MeV=k, respectively.

Viscous evolution of disks for Mdisk = 0.1 M

Rest-mass density in units of g=cm3, temperature (kT) in units of MeV, specific entropy per baryon in units of k, and electron fraction Ye for model K8. The rest-mass density, the value of Ye, and the temperature of the  atmosphere artificially added are ≈10 g=cm3, 0.5, and ≈0.036 MeV=k, respectively.
