Stellar feedback can drive a galactic fountain by pushing out gas that later falls back in.
A previously unexplained branch of cooling white dwarfs is likely a traffic jam caused by an 8 billion year delay in cooling. A heavy isotope of neon settling down into the core of the star could be the source.
What processes will disrupt a cloud of gas passing through the circumgalactic medium?
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.
Many studies have been done within astronomy to investigate gender inequality between men and women. But, what can we do to better support the members of our community who don’t identify as part of the gender binary?
Today’s paper presents an intermediate mass black hole (IMBH) hiding within a dense star cluster. X-ray and optical observations over 15 years allow the authors to explore the different stages of this IMBH feasting on an unlucky star.
