Latest Alan Boss Stories
New modeling studies from Carnegie’s Alan Boss demonstrate that most of the stars we see were formed when unstable clusters of newly formed protostars broke up.
New research from Carnegie Institution for Science looks at how gas giants similar to Jupiter and Saturn formed and evolved. Using theoretical modeling, lead researcher Alan Boss provides clues that gas giants may form in the presence of gas disks that surround stars in their infancy.
It has long been thought that our Solar System was formed by the shockwave from a supernova explosion. According to this theory, the shockwave also injected material from the exploding star into a cloud of gas and dust.
WASHINGTON, Aug. 3 /PRNewswire-USNewswire/ -- NASA will hold a media briefing on Thursday, Aug. 6, at 2 p.m. EDT, to discuss early science results of the Kepler mission.

There might be one hundred billion Earth-like planets in our galaxy, US scientists announced at a recent press conference.
For several decades, scientists have thought that the Solar System formed as a result of a shock wave from an exploding star â€” a supernova â€” that triggered the collapse of a dense, dusty gas cloud that contracted to form the Sun and the planets. But detailed models of this formation process have only worked under the simplifying assumption that the temperatures during the violent events remained constant.
A new explanation for forming "super-Earths" suggests that they are more likely to be found orbiting red dwarf stars -- the most abundant type of star -- than gas giant planets like Jupiter and Saturn.
Last August, two groups of scientists announced the discovery of the smallest extrasolar planets found to date. But just what are these Neptune-size worlds? Are they gas giants, ice giants, or oversized Earths? Astronomer Alan Boss examines the possibilities.
Scientists now believe that the formation of Jupiter, the heavy-weight champion of the Solar System's planets, may have spawned some of the tiniest and oldest constituents of our Solar System -- millimeter-sized spheres called chondrules, the major component of primitive meteorites.
