The sun’s core rotates four times faster than its surface

The sun’s core rotates nearly four times faster than the sun’s surface, according to new findings by an international team of astronomers. Scientists had assumed the core was rotating like a merry-go-round at about the same speed as the surface.

Blast of gamma rays is helping astronomers resolve long-standing questions about universe's most powerful explosions.

An international team of astronomers caught a massive star as it died in a titanic explosion deep in space.

Another Possibility for Tabby’s Star dips

An alternative explanation for Tabby’s star dips: sporadic events blocking stellar flux on the photosphere of the star. Those events can be due to magnetic activity (as with the Sun), differential rotation, sporadic changes in photospheric abundances, or random variations in convective efficiency...

Flow of material is observed for the first time around a young eruptive star

Every year, about two Earth masses of material flows to the disk of the young star V346 Normae from its surroundings, to eventually end up on the star causing a brightening. The hard-to-see phenomenon was captured by a Hungarian-led research group using ALMA, the largest astronomical telescope on Earth. The observation helps in the understanding of a key phenomenon: how circumstellar disks evolve and ultimately form planets.

Blue Large-Amplitude Pulsators (BLAPs) as a new class of variable stars

A new paper published in Nature Astronomy, presents more than a dozen of previously unknown short-period variable stars: blue large-amplitude pulsators (BLAPs).
