There she blows! A detective case tracking the motion of material ejected from a star to figure out when the star exploded.

A gravitational tug-of-war between three stars has this planet living on the edge.
NN Serpentis has everything: a white dwarf + main sequence binary system that is believed to contain two planets and, now, a disc of debris.
How can we explain hot Jupiters? The answer is not completely clear yet, but we are closing in on it: it seems that binaries may play an important role on the formation of these oddball planets.
The latest science from a few early-career researchers.
