A fragment of a planet that has survived the death of its star has been discovered by astronomers in a disc of debris formed from destroyed planets, which the star ultimately consumes.

The discovery, reported in the journal Science, is the first time that scientists have used spectroscopy to discover a solid body in orbit around a white dwarf, using subtle variations in the emitted light to identify additional gas that the planetesimal is generating.

Staff and students from the Physics department will again contribute to Coventry's "Pint of Science" festival this year, to be held from 20-22 May in venues around the city. Departmental representatives include Jessica Marshall, Matthew Hoskin, Sam Seddon, Tishtrya Mehta, and Alun Rees.

Room-temperature spin transport has now been shown in both pivotal semiconductor materials, Ge and Si, providing new opportunities for the future of semiconductor spintronics.

Discovery of Fractional Quantum Hall Effect in a strained Germanium semiconductor indicates superior quality of epitaxial material and offers the simplest system to research quantum physics.
