Life Cycle of a Star Essays
A star's birth starts with a interstellar cloud. A …show more content…
The life span of a star depends on the pressure of the core. Since the inner core of a star is making nuclear fusion it causes the star to expand, because of the energy and heat the nuclear fusion creates. Then, because of the star's gravity in mass, the star's mass gives off a strong power going into the star itself. So, star's mass (stellar mass) is also the determination of a star life. The pushing and pulling of the two gravity's are what give a star it's “twinkling” appearance (Educators and Students) If the stellar mass is low then the temperature will be cold and brightness would be very dim. But, even though the stellar mass is low, it has the longest life span, a life span of ten thousand to two hundred thousand millions of years. If a star has a stellar middle mass, then the temperature of that stare will be intermediate. Also the brightness of the Middle-Mass star will be intermediate. The life span of a intermediate star will be one thousand to ten thousand millions of year. Lastly, if a star has a high stellar mass then the temperature will be extraordinary hot, and it will shine the brightest, out of the three. Even though it has the highest stellar mas, the star also has the shortest life span of ten to one hundred years.
