A young star, a young parent too!

Updated on October 21, 2012

How young star becomes young parent

The formation of stars, planets and satellites was only recently theorized. After the nebula condenses into a gas disk with accretion of dust, the protostar at the centre takes some time to form a protoplanetary disk. The dust particles accumulate more dust which lead to planetisimals. These plantetisimals collide with others, form bigger ones that attract other platetisimals of lower mass. The big ones also form atmospheric layers.

The protostar gradually evolves into a star due to catalytic conditions of thermonuclear fusions. That has an impact on protoplanets which either convert into a megaplanet generally a gas giant. Many of the planets forming, eventually loose their atmospheres due to innumerable collisions with rivals. This explains why we do find many planets but very few of them boast an atmosphere. However, there is a distinct possibility for formation of rocky planets and with seas if comets collide with them as the earth did benefit the same way..

As the days go by, with elaborate missions revealing valuable data, it is now clear that a star that is too young also can form planets of good size if it already has elements heavier than helium. A star with rich metal content such as iron silica, zinc, cobalt, etc., will lineage to an elaborate planetary system for sure.

Here is a video that supports this proposition. A 12 million year old star is considered too young as stars survive billions of years. One such star is already heavy into the action of forming major protoplanets from debris disks.

Improved tools are there to assist the early detection of protoplanets moving and crossing over the host star. As more exoplanets are discovered by Kepler mission aided by impeccable images of Hubble telecope, more information on process of stars and planets will pour in. Forthcoming Webb Telescope has adequate resources to probe deep into protoplanetary formations irrespective of opacity of the dust disks and more is expected to be known.

If a young star is also a young parent of a planet, it is obvious that elaborate planetary systems formation is in the offing and such systems need close watch. Our solar system formation will be revealed to a great extent that way.
