Quasi-stars and the cosmic evolution of massive black holes
We explore the cosmic evolution of massive black hole (MBH) seeds forming within ‘quasistars’ (QSs), accreting black holes embedded within massive hydrostatic gaseous envelopes. These structures could form if the infall of gas into the centre of a halo exceeds about 1 M yr−1. The collapsing gas traps its own radiation and forms a radiation pressure-supported supermassive star. When the core of ...

متن کاملBinary Neutron Stars Systems: Irrotational Quasi-Equilibrium Sequences
We report on numerical results from an independent formalism to describe the quasi-equilibrium structure of nonsynchronous binary neutron stars in general relativity. This is an important independent test of controversial numerical hydrodynamic simulations which suggested that nonsynchronous neutron stars in a close binary can experience compression and even collapse prior to the last stable ci...
متن کاملMassive Stars in Transition
We discuss the various post-main sequence phases of massive stars, focusing on Wolf-Rayet stars, Luminous Blue Variables, plus connections with other early-type and late-type supergiants. End states for massive stars are also investigated, emphasising connections between Supernovae originating from core-collapse massive stars and Gamma Ray Bursts.
متن کاملInstabilities in massive stars
A defining property of massive stars is the dominant, dynamical role played by radiation throughout the stellar interior, atmosphere, and wind. Associated with this radiation hydrodynamics are several distinct kinds of instabilities that can lead to convection in both core and envelope, clumping in atmosphere and wind outflow, and perhaps even the dramatic mass loss outbursts associated with Lu...
