I present, very high resolution hydrodynamical simulations of accretion discs in black hole X-ray binaries accreting near the Eddington limit, including the effects of disc irradiation and mass loss. I show that the extreme variability displayed by sources such as GRS 1915+105 can be explained within the framework of an outburst in a partially irradiated, turbulent, disc.

Resumen

Resumen

Presento simulaciones hidrodinámicas de muy alta resolución de discos de acreción en binarias de rayos X de agujero negro enya acreción se encuentra cerca del limite de Eddington, incluyendo los efectos de irradiación y pérdida de masa. Muestro que la variabilidad extrema de fuentes tales como GRS 1915 + 105 se puede explicar dentro del maico de transferencia de masa en un disco turbulento, parcialmente irradiado.
