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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

Circumstellar disks around red dwarfs like this one are rare to begin with, but this star, called AWI0005x3s, appears to have sustained its disk for an exceptionally long time. The findings are ...
