The critical role of clumping in line-driven disc winds

Amin Mosallanezhad, Christian Knigge, Nicolas Scepi +4

Radiation pressure on spectral lines is a promising mechanism for powering disc winds from accreting white dwarfs (AWDs) and active galactic nuclei (AGN). However, in radiation-hyd…

A Diagnostic Kit for Optical Emission Lines Shaped by Accretion Disc Winds

Austen G. W. Wallis, Christian Knigge, James H. Matthews +2

Blueshifted absorption is the classic spectroscopic signature of an accretion disc wind in X-ray binaries and cataclysmic variables (CVs). However, outflows can also create pure em…
