We see that many stars have a buddy star or two i.e. they are a binary or multi-star system. This paper addresses the question: How in the heck does that happen?
Stellar feedback can drive a galactic fountain by pushing out gas that later falls back in.
Observations of Giant Molecular Clouds (GMCs) yield large scatters in star formation efficiencies. Simulations in this work show that much of this scatter may stem from the fact we observe GMCs at different evolutionary stages driven by stellar feedback.
Does our galaxy look like an Advil, a NyQuil, or just a simple sphere? The simulations studied in today’s paper may have the answer.
Simulations by astronomers at Columbia University suggest an evaporating exomoon could be behind the mysterious dimming behaviour of KIC 8462852.
With an ideal dataset of many localized FRBs, how can the diffuse gas fraction in the IGM be constrained?
