Star formation in the early universe was a vigorous process that created gigantic stars. Called Population III stars, these giants were massive, extremely luminous stars that lived short lives, many ...

The study of these systems is crucial for understanding stellar evolution ... revealing the presence of a geometrically thick accretion disk around the hotter star. The study provided insights ...

A new form of black hole archeology, linking spin to gas and dust, has revealed that these cosmic titans spin faster than ...

Rapid X-ray oscillations detected near the innermost orbit of a supermassive black hole could indicate the presence of a nearby orbiter such as a white dwarf ...

stars notably more metal-poor than stars residing in the galaxy's disk and the inner stellar halo. The astronomers assume that Stream N likely originated from an accretion event. In the opposite ...

which are compact stellar corpses left behind by dying sunlike stars. If the putative object were a smaller black hole, it would’ve plunged headlong through the accretion disk to merge with its ...

Gilat Satellite (GILT) announced that it has successfully closed the acquisition of Stellar Blu, a US-based provider of satellite communications terminal solutions. Gilat expects its annual ...

Recently, the accretion disk began interacting with a second object ... causing bursts of X-rays as it passes through the stellar debris. The regular X-ray bursts observed during the collisions ...
