Carnegie Institution 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. These protostars are born out of rotating clouds of dust and gas, which act as nurseries for star formation. Rare clusters of multiple protostars remain stable and mature into multi-star systems. The unstable ones will eject stars until they achieve stability and end up as single or binary stars. The work is...

Giants Like Jupiter May Have Formed In The Gas Disk Of Young Stars

Lawrence LeBlond for redOrbit.com - Your Universe Online 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. The work was recently published in the Astrophysical Journal. By observing young stars that are surrounded by gas disks, Boss demonstrated that...

Supernova Shock Wave And Its Role In Solar System Formation
2012-08-03 09:04:16

April Flowers for redOrbit.com - Your Universe Online 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. The newly polluted cloud formed the Sun and its surrounding planets. A new study by Alan Boss and Sandra Keiser of the Carnegie Institution for Science, published in The Astrophysical Journal Letters, provides the...

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. Kepler is the first spacecraft with the ability to find Earth-size planets orbiting stars like our sun in a zone where liquid water could exist.

There might be one hundred billion Earth-like planets in our galaxy, US scientists announced at a recent press conference. Dr Alan Boss of the Carnegie Institution of Science stated that maybe a few of these could have simple life forms living on them. Boss announced this at the yearly meeting of the American Association for the Advancement of Science in Chicago. Thus far, telescopes have found 300 planets outside our solar system. However, only a few would be able to support life. The...

For several decades, scientists have thought that the Solar System formed as a result of a shock wave from an exploding star "” a supernova "” 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. Now, astrophysicists at the Carnegie Institution's Department of...

Washington, DC. -- 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. The theory, by Dr. Alan Boss of the Carnegie Institution's Department of Terrestrial Magnetism, describes a mechanism whereby UV radiation from a nearby massive star strips off a planet's gaseous envelope exposing a super-Earth. The work, published in the June 10, 2006,...

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. Astrobiology Magazine -- Over the past decade, astronomers using a planet-hunting technique that measures small changes in a star's speed relative to Earth, have discovered more than 130 extrasolar planets. The first such planets were...

Carnegie -- 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. The study, by theorists Dr. Alan Boss of the Carnegie Institution and Prof. Richard H. Durisen of Indiana University, is published in the March 10, 2005, issue of The Astrophysical Journal (Letters)....
