Astronomers detect an outbursting young stellar object

By analyzing datasets from the Palomar Gattini InfraRed survey (PGIR) and NASA's NEOWISE spacecraft, astronomers have identified an outbursting young stellar object (YSO) in the star-forming region NGC 281-W. The study, which ...

Turbulent convection at the heart of stellar activity

In their interiors, stars are structured in a layered, onion-like fashion. In those with solar-like temperatures, the core is followed by the radiation zone. There, the heat from within is led outwards by means of radiation. ...

Supercharged light pulverises asteroids, study finds

The majority of stars in the universe will become luminous enough to blast surrounding asteroids into successively smaller fragments using their light alone, according to a University of Warwick astronomer.

V473 Lyr has a low-mass companion, study suggests

Using ESA's XMM-Newton spacecraft, astronomers have conducted X-ray observations of a peculiar Cepheid variable star known as V473 Lyr. Results of the study suggest that this star has a young, low-mass companion. The finding ...

Old at heart: A solution to red giants' age paradox

Four years ago, several red giant stars were discovered to pose a paradox: even though they are built from very old stellar material, their large masses indicate a clearly younger age. Scientists from the Max Planck Institute ...
