Astronomers have struggled to understand how the largest stars — up to 120 times as massive as the Sun — can form by sucking in nearby matter. The problem is that, once a star reaches about 20 solar masses, the outward force of its intense radiation exceeds the gravitational force that pulls in matter.

Web29 de mai. de 2024 · How is a Protostar Formed? Inside a nebula, there are areas where gravity causes dust and gas to “clump” together. As these “clumps” gather more and more mass their gravitational pull increases, forcing more atoms together. This process is known as accretion, and the result is a protostar. What is the first step in the formation of a ... A protostar is a very young star that is still gathering mass from its parent molecular cloud. The protostellar phase is the earliest one in the process of stellar evolution. For a low-mass star (i.e. that of the Sun or lower), it lasts about 500,000 years. The phase begins when a molecular cloud fragment first collapses under the force of self-gravity and an opaque, pressure supported c…

This process is known as accretion. As gravity pulls the gasses closer to the center of the ball, gravitational energy begins to heat them, causing the gasses to emit radiation. At first, the radiation simply escapes into space. rd1txWebProtostar. Thanks to Viktor Ambartsumian, a Soviet physicist, who proposed the existence of a protostar.
