Models of Soft X-Ray Transients and Dwarf Novae

TL;DR

This paper presents models of Soft X-Ray Transients, emphasizing the role of inner advection-dominated flows and disc stability, and compares these models with observations and dwarf nova systems.

Contribution

It introduces models highlighting the significance of inner advection-dominated flows and examines their stability, comparing them with dwarf nova models and observational data.

Findings

Inner advection-dominated flows are crucial in quiescent transient sources.

Global stability issues are identified in standard outer accretion disc models.

Comparisons with dwarf nova models reveal similar stability problems.

Abstract

Models of Soft X--ray Transients are presented and compared with observations. The importance of inner advection--dominated flows in quiescent transient sources is discussed, as well as the problem of global stability of the standard outer accretion disc. A comparison is made with similar problems in dwarf nova models.
