How do bound star clusters form?
Today’s paper tests five different models of star cluster formation to find out how gravitationally-bound star clusters form in our Universe.
Elusive black holes: Have we found the ‘middle sibling’?
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.
Dwarf Galaxies without Dark Matter
Today’s paper looks at observations of 19 low mass galaxies which appear to contain no dark matter, potentially challenging our overall understanding of galaxy formation.
Subgiant in the spotlight: characterising a new benchmark star
Today’s authors take a multi-faceted approach to characterising a benchmark subgiant star using asteroseismology, interferometry, and spectroscopy.
A Historical Nova and the First Radioactive Molecule in Space
An explosive stellar merger reveals the first radioactive molecule discovered in space.
Moonetesimals likely form relatively quickly
The absence of dusty circumplanetary disks around young giant planets suggests moonetesimals grow relatively quickly.
