Study of ‘polluted’ white dwarfs finds that stars and planets grow together

Astronomers have discovered evidence that planetary formation can begin very quickly after the birth of a star. This incredible insight into the histories of planetary systems comes from white dwarfs, the dying remnants of the cores of stars like our Sun, rather than from...

How planets can be an anti-aging formula for stars

Tidal pressures exerted by a hot Jupiter may cause its host star to spin faster than it would without the planet. Because of its faster rotation, the host star may become more active and emit more X-rays, which are typical of young stars. A new...

First time spotted pulsating core of a massive star

A well-known bright star in the southern skies may be a "unique object" that has remained "hidden in plain sight" until now, according to a new study, a discovery that may offer an unprecedented glimpse into the mysterious innards of stars. Gamma (γ) Columbae, a star...

Young star-forming complexes detected in the galaxy NGC 4324

Russian astronomers used the Caucasus Mountain Observatory to investigate NGC 4324, a nearby lenticular galaxy. They discovered young star-forming complexes in this galaxy's inner ring. The findings, which were published on arXiv.org on October 14, may help us understand the formation and evolution of...

Theoretical physicists argue that black holes admit vortex structures

Black holes are astronomical objects with extremely strong gravitational pulls that cannot be overcome by light. While the concept of light-trapping bodies has been around since the 18th century, the first direct observation of black holes occurred in 2015. Since then, physicists have conducted a...

Denser and more turbulent environments tend to form multiple stars, study finds

Astronomers studying stellar nurseries in the Milky Way discovered that nearly half of the stars in the galaxy are formed in binary/multiple stellar systems (think twins, triplets, quadruplets). Despite the prevalence of binary/multiple births, previous stellar nursery studies have focused on how single stars form....
