Supercritical Accretion Flows around Black Holes: Two-dimensional, Radiation Pressure-dominated Disks with Photon Trapping
TL;DR: In this article, the quasi-steady structure of supercritical accretion flows around a black hole is studied based on two-dimensional radiation-hydrodynamic (2D-RHD) simulations.

TL;DR: In this paper, the authors compared 11 independent radiative transfer (RT) codes on five test problems: (0) basic physics; (1) isothermal H II region expansion; (2) H II Region expansion with evolving temperature; (3) I-front trapping and shadowing by a dense clump and (4) multiple sources in a cosmological density field.
Journal ArticleDOI
Formation, early evolution, and gravitational stability of protoplanetary disks
TL;DR: In this article, the formation, viscous evolution, and gravitational stability of protoplanetary disks are investigated, and the axisymmetric gravitational stabilities of the disks are checked using Toomre's criterion.
Journal ArticleDOI
Evolution of snow line in optically thick protoplanetary disks: effects of water ice opacity and dust grain size
TL;DR: In this article, the evolution of a snow line in an optically thick protoplanetary disk is investigated with numerical simulations, and it is shown that the snow line migrates as the mass accretion rate in the disk decreases with time.
