On An Hr Diagram A Protostar Would Be

As protostars contract to the main sequence both their luminosities and their surface temperatures change. Such a path on the hr diagram for a star or a protostar is called an evolutionary track.

Star Formation

3 below and near the right side of the main sequence.

On an hr diagram a protostar would be. When helium fusion begins in the core of a red giant star the situation quickly gets out of control because electron degeneracy pressure does not respond to changes in. 4 below and to the left of the main sequence. However the outer layers of this protostar are cooler than the sun so the point we plot on the hr diagram for this protostar is above and to the right of the suns current location in the diagram temperature about 3500 k.

Most stars probably all stars formed in a cluster of stars subscribe to view the full document. A star burning hydrogen into helium in a shell around the core. As the protostar continues to contract its outer layers will heat up.

On an h r diagram a protostar would be above and to the right of the main sequence 27. 1 on the main sequence at the extreme lower right. Therefore we may envision them following a path in time on the hr diagram.

Stellar evolutionary tracks in the hr diagram. Motion on the hr diagram. 5 above and near the upper left of the main sequence.

2 above and to the right of the main sequence. The single most important determinant of the temp density radius luminosity and pace of evolution of a protostar is its. Explain the interplay between gravity and pressure and how the contracting protostar changes its position in the hr diagram as a result one of the best ways to summarize all of these details about how a star or protostar changes with time is to use a hertzsprung russell hr diagram.

As a clump of interstellar gas contracts to become a main sequence star its changing position on the h r diagram tells us.
