Enormous 'superflare' detected on nearby star

Science Daily Astronomy - Thu, 2020-07-09 11:35
Astronomers succeeded in detecting 12 stellar flare phenomena on AD Leonis. One of these flares was 20 times larger than those emitted by our own sun, categorizing it a 'superflare'. Subsequent data analysis presents new insight into these explosive phenomena.

How colliding neutron stars could shed light on universal mysteries

Science Daily Astronomy - Wed, 2020-07-08 12:14
Researchers have discovered an unusual pulsar - one of deep space's magnetized spinning neutron-star 'lighthouses' that emits highly focused radio waves from its magnetic poles. It is unusual because the masses of its two neutron stars are quite different -- with one far larger than the other. The breakthrough provides clues about unsolved mysteries in astrophysics -- including the expansion rate of the Universe (the Hubble constant).

New collection of stars, not born in our galaxy, discovered in Milky Way

Science Daily Astronomy - Tue, 2020-07-07 11:32
Astrophysicists announced the discovery of Nyx, a new collection of 250 stars that they believe are the remnant of a dwarf galaxy that merged with the Milky Way eons ago. The research combined massive cosmological simulations and observational data from the Gaia space observatory. It required large scale supercomputers and deep learning algorithms. The team plans to explore Nyx further using ground-based telescopes.

White dwarfs reveal new insights into the origin of carbon in the universe

Science Daily Astronomy - Mon, 2020-07-06 14:08
A new analysis of white dwarf stars supports their role as a key source of carbon in galaxies. Every carbon atom in the universe was created by stars, but astrophysicists still debate which types of stars are the primary source of the carbon in our galaxy. Some studies favor low-mass stars that blew off their envelopes in stellar winds and became white dwarfs, while others favor massive stars that eventually exploded as supernovae.
