Modelling supermassive black hole growth: towards an improved sub-grid prescription
Modelling supermassive black hole growth sub-grid prescription
2012/2/24
Accretion onto supermassive black holes (SMBHs) in galaxy formation simulations is frequently modelled by the Bondi-Hoyle formalism. Here we examine the validity of this approach analytically and nume...

The mass-loss rates of red supergiants the de Jager prescription
2011/1/11
Mass loss of red supergiants (RSG) is important for the evolution of massive stars, but is not fully explained. Several empirical prescriptions have been proposed, trying to express the mass-loss rate...
