WebMay 7, 2015 · On the right of the illustration is the life cycle of a massive star (10 times or more the size of our Sun). Like low-mass stars, high-mass stars are born in nebulae and evolve and live in the Main Sequence. … WebDec 22, 2015 · In 3.5 billion years from now, the Sun will be 40% brighter than it is right now. This increase will cause the oceans to boil, the ice caps to permanently melt, and all water vapor in the ...

Stellar evolution is the process by which a star changes over the course of time. Depending on the mass of the star, its lifetime can range from a few million years for the most massive to trillions of years for the least massive, which is considerably longer than the current age of the universe. The table shows the … See more Protostar Stellar evolution starts with the gravitational collapse of a giant molecular cloud. Typical giant molecular clouds are roughly 100 light-years (9.5×10 km) across and contain up to 6,000,000 See more After a star has burned out its fuel supply, its remnants can take one of three forms, depending on the mass during its lifetime.

WebCollege of Science and Engineering University of Houston-Clear Lake WebIf we adopt a main-sequence lifetime of the Sun of 1010 years, then τMS = 10 10 µ M M¯ ¶1−η years Since η ∼ 3.5, the main-sequence lifetime of a star is a strong function of its mass. When the mass fraction of hydrogen in a stellar core declines to X ∼ 0.05 (point 2 on the evolutionary track), the main-sequence WebAnswer : Below are the evolution stages of high mass star ; 1) Main sequence star ….
