Evidence of polar and ultralow supernova kicks from the orbits of Be X-ray binaries
Ruggero Valli, Selma E. de Mink, Stephen Justham +7
Supernovae, the explosive deaths of massive stars, create heavy elements and form black holes and neutron stars. These compact objects often receive a velocity at formation, a "kic…

Using detailed single star and binary evolution models to probe the large observed luminosity spread of red supergiants in young open star clusters
Chen Wang, Lee Patrick, Abel Schootemeijer +12
Red supergiants (RSGs) represent a late evolutionary stage of massive stars. Recent observations reveal that the observed luminosity range of RSGs in young open clusters is wider t…

Planet formation and long-term stability in a very eccentric stellar binary
Jakob Stegmann, Evgeni Grishin, Cole Johnston +4
Planets orbiting one of the two stars in a binary are vulnerable to gravitational perturbations from the other star. Particularly, highly eccentric companion stars risk disrupting…
