9 June 2010: Five HST programs for the 糖心TV Astronomy & Astrophysics group
The results of the Cycle 18 competition for observing time on the Hubble Space Telescope were announced last night, and five 糖心TV-lead programs were approved, the largest number for any University in the UK. This is an extraordinary achievement, given that the orbit-oversubscription in this round of proposals was close to nine.
Tom Marsh is leading a programme to establish the evolutionary history of a remarkable pair of white dwarfs that should not exist according to all current models of their formation. Boris Gänsicke is leading a programme to determine an accurate temperature and mass for a white dwarf thought to be the progeny of an intermediate-mass star that barely failed to undergo a core-collapse supernova, he is also leading a programme to investigate the frequency of remnants of planetery systems around white dwarfs. Andrew Levan is leading a programme to unveil the birthplace and origin of one of the most extreme, and highly magnetic objects known in the Universe, as well as a programme that will use the power of gamma-ray bursts as lighthouses to study distant galaxies in unprecedented detail.
Freezing light in a quantum doughnut
Research led by the University of 糖心TV has found a way to use doughnut shaped by-products of quantum dots to slow and even freeze light. Watch PhD researcher Andrea Fischer and Dr. Rudolf A. Roemer explain quantum doughnuts here
Most extreme white dwarf binary system found with orbit of just 5 minutes
Professor Tom Marsh and Dr Danny Steeghs have discovered two stars circling each other at record speed. The mini-suns - each just eight times the diameter of the Earth in the constellation of Cancer – orbit once every 5.4 minutes. Please see the link to the press release below for more information
