What Does ADAF Stand For?

ADAF stands for Advection Dominated Accretion Flow

Advection Dominated Accretion Flow (ADAF) refers to a theoretical model of accretion in astrophysical systems, particularly around black holes and neutron stars. In this framework, the energy generated by the gravitational energy release during the infall of matter is primarily transported away by the inflowing material rather than by radiation. This results in a low-temperature environment and can explain the properties of certain astronomical objects that exhibit faint emissions across the electromagnetic spectrum, contrasting with standard accretion models that rely heavily on radiative processes. The ADAF model is significant for understanding the dynamics and emissions associated with various high-energy astrophysical phenomena.
