Using data obtained from surveys of stars in the Milky Way and some clever programming, it is now possible to find stellar siblings scattered throughout our Galaxy, and thus obtain invaluable information on its evolution.
Astronomers may have finally observed the event that explains polluted white dwarfs and their debris disks.
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.
Today we use a new paper to revisit the possible dwarf galaxy discovered 90 kpc from the Milky Way.
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.
Images from the Hubble Space Telescope show that there are previously unknown white dwarfs orbiting around pulsar companions.
