It takes two: the energy budget of common envelope evolution
Rebassa-Mansergas et al. investigate two long period post common envelope systems in order to place constraints on the energy budget for common envelope evolution.

The Center of our Galaxy is one of the most extreme dynamical environments we can observe in detail because individual stars can actually be resolved using adaptive optics. Over time, monitoring individual stellar orbits has firmly established the presence of a supermassive black hole of about 4 x 106 M☉ (check out this video too). Further examination of these fast-moving stars’ properties (via infrared spectroscopy) revealed a surprising detail — many of these stars are young!
Schaefer & Pagnotta search supernova remnant 0509-67.5 for signs of an ex-companion to the white dwarf which exploded as a type Ia supernovae.
N. Prantzos investigates whether the bulk of Galactic cosmic rays can be accounted for by supernovae remnants
Nordhaus et al perform simulations to show that normal type II supernovae can produce pulsar kicks which match the observed velocities of neutron stars.
