The APOGEE Treasure Trove

The APOGEE Treasure Trove

The three-year APOGEE survey was designed to target red giant stars in the Milky Way using near-infrared light, and today’s paper marks the final data release: half a million spectra of 146,000 stars. This treasure trove of data will be put to good use for years to come.

The Magnetic Personalities Of Dead Stars

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.
