description Andrew King Overview
Andrew King is a British theoretical astrophysicist associated with the University of Leicester. His research addresses accretion discs, compact binary systems, active galactic nuclei, and the evolution of X-ray binaries. He is also known for theoretical work explaining ultraluminous X-ray sources through super-Eddington accretion and geometrically beamed radiation from compact objects.
help Andrew King FAQ
What does Andrew King study in theoretical astrophysics?
Andrew King studies accretion discs, compact binary systems, active galactic nuclei, and X-ray binaries. He is associated with the University of Leicester in the United Kingdom.
What is an accretion disc in Andrew King's research?
An accretion disc is a rotating structure of gas and dust falling toward a compact object such as a black hole or neutron star. Friction and compression can make the disc emit large amounts of radiation.
What are ultraluminous X-ray sources?
Ultraluminous X-ray sources are off-nuclear sources whose X-ray output is much greater than that of typical stellar-mass X-ray binaries. Andrew King is known for theoretical work on how such systems can produce extreme luminosities.
How are X-ray binaries connected to Andrew King's work?
An X-ray binary contains a compact object drawing material from a companion star, often through an accretion disc. King has studied how these systems evolve and how their accretion produces X-rays.
