Colliding Black Holes Tell New Story of Stars
Just months after their discovery, gravitational waves coming from the mergers of black holes are shaking up astrophysics.
Selma de Mink of the University of Amsterdam has devised a new theory stating that pairs of black hole close enough to merge come from massive stars whose contents have been mixed until they are homogeneous throughout.
The R136 star cluster at the heart of the Tarantula Nebula gives rise to many massive stars, which are thought to be the progenitors of black-hole binaries.
All Spun Up
Daniel Holz of the University of Chicago works on the classic common-envelope explanation for the formation of black-hole binaries.
