UChicago scientists have discovered evidence in a meteorite that a rare element, curium, was present during the formation of the solar system. The finding ends a 35-year-old debate on its possible pre...
Infant planetary systems are usually nothing more than swirling disks of gas and dust. Over the course of a few million years, this gas gets sucked into the center of the disk to build a star, while t...
Scientists at the University of Arizona have discovered what might be the closest thing to "baby photos" of our solar system. A young star called HD 95086 is found to have two dust belts, analogous to...
Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have observed what may be the first-ever signs of windy weather around a T Tauri star, an infant analog of our own Sun. This m...
Will 3552 Don Quixote Escape from the Solar System?
Asteroid: orbital evolution- Solar System: N-body problems
2011/9/28
Asteroid 1983 SA, well known as 3552 Don Quixote, is one of Near Earth Asteroids (NEAs) which is the most probable candidate for the cometary origin, or otherwise as Jupiter-Family-Comets (JFCs). The ...

Transport of First Rocks of The Solar System by X-winds
Earth and Planetary Astrophysics (astro-ph.EP) Solar and Stellar Astrophysics (astro-ph.SR)
2010/12/29
It has been suggested that chondrules and calcium-aluminum-rich inclusions (CAIs) were formed at the inner edge of the protoplanetary disk and then entrained in magnetocentrifugal X-winds. We study tr...
Rotation of the Solar System planets and the origin of the Moon in the context of the tidal downsizing hypothesis
Earth and Planetary Astrophysics (astro-ph.EP)
2010/12/27
It has been proposed recently that the first step in the formation of both rocky and gas giant planets is dust sedimentation into a solid core inside a gas clump (giant planet embryo). The clumps are ...
