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 ...

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 ...

Planets may begin forming much earlier than scientists once believed during the final stages of a star s birth, not afterward. This bold new model, backed by simulations from researchers at SwRI, ...

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 Pictoris ...

Southwest Research Institute scientists propose a new model for the formation of compact exoplanetary systems that contain multiple rocky planets in tight orbits around their star. In this model, ...
