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 ...

Researchers analyzed the accumulated data from the Atacama Large Millimeter/submillimeter Array (ALMA) and depicted the motion of a young twin star system XZ Tauri over three years. This first-ever ...

Astronomers have gained new insight into the formation of planets around twin stars that orbit one another. Despite the fact we are most familiar with planets orbiting a single, central star — like ...

Be stars are non-supergiant B-type stars that exhibit Balmer emission lines arising from a gaseous, equatorial circumstellar disc. These stars rotate at velocities approaching their critical break-up ...

Astronomers recently imaged two budding stars locked in a gravitational waltz that twisted their planet-forming disks into a pretzel-shaped knot. “We see two compact sources that we interpret as ...

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 ...

This one-million-year-old star-forming region contains thousands of new stars and hundreds of planetary mass objects floating freely in the nebula, not orbiting stars. A groundbreaking study published ...

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 ...

The week I started graduate school, the first science projects were announced for the new Atacama Large Millimeter/submillimeter Array (ALMA) telescope in Chile. This groundbreaking facility uses ...

Do you know that there are countless diamonds in space? Loads of tiny diamonds, each measuring one micrometer (less than the width of a human hair) are located in the material that surrounds some ...

An artistic rendering of a dust and gas disk encircling the young exoplanet, CT Cha b, 625 light-years from Earth. Spectroscopic data from NASA’s JWST suggest the disk contains the raw materials for ...
