Extremely high pressures build up inside the ball, which in turn causes the tightly packed atoms to heat up. As the temperature climbs, the ...

Disks around new stars and planet formation
... Stars form within dense clouds of molecular gas from disks of gas & dust. Disks regulate accretion onto the star & act as a launching point for the outflow. Planets form later from the remnants of the disk (debris disk). Planets have been detected around “solar-type” stars but we have not imaged a p ...
