Specific angular momentum of the accreting matter around a rapidly rotating non-magnetized degenerate dwarf star of very low mass

摘要

Due to the presence of an accretion disc, the steller angular velocity increases and in the process of increment when the stellar angular velocity reaches to a critical value, a self-consistent regime of accretion is. established, in which the specific angular momentum of the accreting matter z equal to the mass derivative of the angular momentum of the stellar body along the sequence of the critically rotating stars An effort is made to search for thai expression for specific angular momentum of the accreting matter around a rapidly rotating non-magnetized degenerate dwarf star of very low mass, A study is made on the existence of a self-similar solution in which the stellar structure and angular velocity law do not depend upon stellar mass for an appropriate choice of non-dimensional variables.
