Document Summary
As102 final questions: dark matter & dark energy, black body. Dark matter has effect on the gravity black body: any body who emit the bell shaped curve: the relationship among, temperature, size, distance, luminosity, flux, angular momentum l=mass * velocity * radii, hayashi track: A protostar(large and luminous) burns hydrogen to arrive in the main sequence, while the protostar gets to less and less luminous, and smaller. As it shrinks, the temperature rises in the core, and starts hydrogen fusion into helium. If the protostar"s mass is small, the star will fail and become brown dwarf. the mass of at least 0. 08 times of the mass of the sun is needed to becomes a star. When a star runs out of hydrogen, the helium becomes ash in the core. Lastly, it leaves the main sequence with the same path it comes. Does every star has the day? and the description is correct: star and planet.
