These disks are made up of the debris left behind by all the collisions during planet formation and by subsequent collisions of the newly formed planets.
This supports the idea that a young planetary system can inherit the chemical composition of its parent star - forming cloud and opens up the possibility that organohalogens could arrive on planets in young systems during planet formation or via comet impacts.
It could have been ejected by a collision during planet formation, sent hurtling free of the star's gravitational grasp approximately 40 million years ago.
Some studies estimate that during planet formation, 20 - 30 percent of planets acquire moons moving inward and destined for destruction, though they would have long since disappeared.

«If we can understand the chemical complexity of these ices in the molecular cloud, and how they evolve during the formation of a star and its planets, then we can assess whether the building blocks of life should exist in every star system,» said Melissa McClure of the Universiteit van Amsterdam, the principal investigator on a research project to investigate cosmic ices.
New research from The University of Texas at Austin adds evidence to a theory that claims the metallic cores of rocky planets like Earth were formed when molten metal trapped between grains of silicate rock percolated to the center of the planet during its early formation.
The Oort cloud consists of objects ejected from the region surrounding the giant planets during and after their formation.
The team suggest that the asteroid was very likely to have been ejected from its binary system sometime during the formation of planets.
There are many possible sources for the components of Earth's primordial atmosphere, from the so - called solar nebula, a cloud of dust and gas leftover from the sun's formation, to comets and other impactors that may have delivered significant amounts of chemicals to Earth during or after the planet's formation.
If confirmed by further research, the new study would challenge a theoretical model for atmosphere formation in which Earth began with two reservoirs of solar gas captured during the planet's formation and youth — one surrounding the planet, the other buried beneath the surface.
Meteorites as a whole are still important clues about what processes occurred during the formation of the solar system, but which ones are the best analogs for what the planets were made out of would change.»

We've recently realized that planets can migrate during solar system formation, moving closer to or farther away from their central star.

A likely explanation is that planets migrate during formation, and that red dwarfs are extremely efficient at moving their planets close to the star where Kepler can observe them (Figure 4).
All rocky planets in the Solar System likely went through a magma ocean stage during their formation and accretion.
«During formation, this ball of featureless rock metamorphosed into a diverse and fascinating planet, almost like caterpillar to a butterfly,» Banerdt said.
But there shouldn't be enough material available during the creation of red dwarfs to allow the formation of giant, Jupiter - class planets in the protoplanetary disk.
«Our analysis shows that a slow, smooth, migration of the system during its formation and evolution would be able to place these planets into the delicately balanced configuration that we observe today,» Ford said.
By studying these stars, and using additional telescope facilities such as the powerful Atacama Large Millimeter / submillimeter Array (ALMA) in Chile, the study will provide new and unique insight into the timescale for the formation of stars and planets, including whether planets form during or after the assembly of the star.
Some astronomers have speculated that inner Oort Cloud objects could even be extra-Solar planets gravitationally captured from neighboring stars during the formation of the Solar System.
One theory suggests, however, that its extreme tilt could have been created by a series of smaller shifts through orbital migrations and interactions between the giant planets during the earliest stages of Solar System formation (Adrián Brunini, 2006).
On December 1, 2009, two astronomers submitted a pre-print suggesting that the planet's extreme axial tilt (an obliquity of 97 degrees) may have resulted from the presence of a large moon that has since been ejected from orbit around the ice giant by the pull of another planet during the orbital migration of the giant planets early in the formation of the Solar System.
Scientists believe that another planet collided with Earth during the latter stages of its formation, creating debris that became the moon and causing Earth to melt down to its core.
By the predominant theory at the time that I knew, we had a single predecessor star, Population II or perhaps even III, and possibly some additional stuff from the interstellar medium got mixed in during the formation of the current star and planets.
