This is less a physical question than a moral one. Should we feed a black hole? If we do, will it ever learn to feed and fend for itself independently? Will it ever truly be able to return to the wild, or will it ever after be chained to the yoke of domestic comfort?
Sherlocks Holmes investigates the scene of a crime for clues about whodunit. Today’s paper investigates the massacre of circumstellar disks in a star cluster for clues about the cluster itself.
Magnetic fields are believed to play an integral role in the formation of stars and protoplanetary disks. Today’s article took the one of the closest looks ever at the magnetic field around a baby star and unveiled its underlying structure.
More than 100 massive stars orbit the supermassive black hole at the center of our galaxy incredibly closely.
Molecular clouds, where new stars are born, are made of two components: gas and dust. The gas is mostly hydrogen, and the dust is made of elements crucial for forming planets and people, like silicon and carbon. Today’s paper shows that these two components behave very differently in a simulated molecular cloud. This could have exciting consequences for the growth of dust and the formation of stars and planets.
Observations of dwarf galaxies show that sites of active star formation have fewer metals. These galaxies may have been diluted by the impact of pristine gas from the cosmic web.
