A team led by a University of Oklahoma astrophysicist discovered a rare and surprising new circumstellar disk: the oldest of its kind. They made this discovery working together with a remarkable team ...

Astronomers have used NASA’s Hubble Space Telescope to take the most detailed picture to date of a large, edge-on, gas-and-dust disk encircling the 20-million-year-old star Beta Pictoris. Beta ...

Be stars, a sub-class of B-type stars, are distinguished by their rapid rotation and the presence of prominent emission lines in their spectra, associated with circumstellar gaseous disks. These disks ...

TOKYO, March 3 (UPI) --Astronomers in Japan have identified a newborn star enveloped by a growing blanket of gas. Using the Atacama Large Millimeter Array, an observatory in Chile, a team of Japanese ...

A group of citizen scientists and professional astronomers joined forces to discover an unusual hunting ground for exoplanets. They found a star surrounded by the oldest known circumstellar disk -- a ...

WASHINGTON, Nov 29 (Reuters) - Our sun and other stars form when a dense clump of interstellar gas and dust collapses under its own gravitational pull. Once a star is born at the center of such a ...

Circumstellar disks as a research area encompasses the observational, theoretical, and computational study of gas and dust structures surrounding young and evolved stars, with emphasis on their ...

When you observe a distant star, you expect its brightness to be something that's fairly uniform. Sure, some stars vary in brightness periodically -- even our Sun does -- but those intrinsic ...

When the disks of gas and dust that surround young stars are misaligned, a phenomenon predicted by models - known as "disk tearing" - does appear to occur, according to a new observational study of a ...

BERKELEY, CA -- By measuring polarized light from an unusual exploding star, an international team of astrophysicists and astronomers has worked out the first detailed picture of a Type Ia supernova ...
