On the isotropy of viscosity in accretion discs
Chris Nixon, Jim Pringle
Accretion discs are fundamental to many astrophysical systems, providing the conversion of gravitational potential energy into radiation that we can observe. In many systems there…
A self-consistent model for the evolution of the gas produced in the debris disc of Pictoris
Quentin Kral, Mark Wyatt, Robert Carswell +3
This paper presents a self-consistent model for the evolution of gas produced in the debris disc of Pictoris. Our model proposes that atomic carbon and oxygen are created from…
Be star discs: powered by a non-zero central torque
Chris Nixon, Jim Pringle
Be stars are rapidly rotating B stars with Balmer emission lines that indicate the presence of a Keplerian, rotationally supported, circumstellar gas disc. Current disc models, ref…
The Relationship between Accretion Disc Age and Stellar Age and its Consequences for Proto-Stellar Discs
Michael Jones, Jim Pringle, Richard Alexander
We show that for young stars which are still accreting and for which measurements of stellar age, disc mass and accretion rate are available, nominal disc age (Disc Age = Disc Mass…
The final parsec problem: aligning a binary with an external accretion disc
Chris Nixon, Andrew King, Jim Pringle
We consider the interaction between a binary system (e.g. two supermassive black holes or two stars) and an external accretion disc with misaligned angular momentum. This situation…
