The Magnetic Personalities Of Dead Stars

The galaxy is littered with white dwarfs, the burnt out remnants of stars that have run out of hydrogen fuel in their cores, but were too small to explode as supernovae. But far from being lifeless orbs, around a tenth of white dwarfs have powerful magnetic fields, a million times stronger than that of the Sun. How did these magnetic white dwarfs become such strong magnets? And just how many are there. The authors of this paper set out to answer the second of these questions, in the hope that it would shed light on the first.

ESPRESSO: A scientific Pandora’s box

ESPRESSO: A scientific Pandora’s box

Are you on the lookout to see if there are habitable planets are out there? Or do you want to see how or if physical ‘constants’ have varied with time? Why not design a versatile instrument capable at tackling a wealth of outstanding questions in astronomy: a sort of a “scientific pandora’s box” for extremely high precision astronomical research? This is where ESPRESSO comes in…
