Subject: Colloquium 23/3/2016: "White Dwarfs: why all astronomers should love them" Martin Barstow (Leicester)

Next week's colloquium will be given by Prof Martin Barstow (Leicester) on white dwarf stars. Prof Barstow is the President of the Royal Astronomical Society. As usual, there will be tea/coffee afterwards.

Title: White Dwarfs: why all astronomers should love them
Speaker: Prof Martin A. Barstow, Department of Physics and Astronomy, University of Leicester
Venue: John Anderson Building JA3.14
Time/Date: 3pm Wednesday 23rd March 2016

Abstract:
White dwarfs may just be the dying embers of the vast majority of stars in the galaxy, but they are of enormous importance for astrophysics. They are implicated in the mechanisms for the supernovae type Ia explosions used to determine the age and scale of the Universe; they can be used as background sources to probe the structure of the galaxy; their atmospheres bear the imprint of debris from rocky extra-solar planets and finally, they can be used to probe variations of fundamental constants in strong gravity. This talk will survey scientific results from the study of white dwarfs and show how they can contribute to understanding of several fundamental problems facing astronomers.
