WebbThe Figure 1 shows the life track of a 1M Sun protostar from the time it first begins to form until it reaches the main sequence, with four stages labeled. What is happening to the … WebbThis is a plot of temperature versus brightness, and as stars are born, live and die, they move in regular patterns around the Hertzsprung-Rusell diagram. The first stage is when a cloud of gas and dust starts to collapse on itself. This is called a protostar and can be a very energetic stage with jets of material being blown out as well as in.
Observational evidence of the Hayashi track comes from color-magnitude plots—the observational equivalent of HR diagrams—of young star clusters. For Hayashi, NGC 2264 provided the first evidence of a population of contracting stars. In 2012, data from NGC 2264 was re-analyzed to account for dust reddening and extinction. The resulting color-magnitude plot is shown at right. WebbMotion on the HR Diagram As protostars contract to the main sequence, both their luminosities and their surface temperatures change. Therefore, we may envision them …
