On the main sequence massive stars quizlet
WebDuring this stage, the star is burning hydrogen to helium in its core, and so it is sitting on the Main Sequence. Depending on its mass, it may live only 1-100 million years in this stage--much shorter than the Sun's lifetime. Once the high mass star starts to run out of hydrogen in the core, and starts burning hydrogen in the shell, it expands ... WebStars more than 8-10 times the mass of the Sun are considered to be massive. Our Sun is currently at an equilibrium stage called the "Main-sequence phase". It will evolve into a "Red Giant" in a billion years time. The internal structure of …

Consider taking a star and increasing its mass by pouring a little extra hydrogen gas onto it. Higher mass leads to Higher compression, …
WebOne-Solar Post-Main Sequence Evolution. Stars such as our Sun move off the main sequence and up the red giant branch (RGB), fusing hydrogen into helium in hydrogen shell burning. A very short helium flash sees the start of helium core fusion and the star moves along the horizontal branch (HB). Once shell temperature is sufficient, helium shell ... WebMain-sequence stars below 0.4 M☉ undergo convection throughout their mass. When core convection does not occur, a helium-rich core develops surrounded by an outer layer of hydrogen. The more massive a star is, the shorter its lifespan on the main sequence.

A red dwarf, which … WebA star forms from massive clouds of dust and gas in space, also known as a nebula. Nebulae are mostly composed of hydrogen. Gravity begins to pull the dust and gas …
WebMassive Stars When a star is more than ten times as massive as the sun, it becomes a Supergiant star. Supergiants have the shortest lifespans of any star, as the temperatures in a supergiant's core get so high that it is able to fuse the helium that is left over after hydrogen burning has stopped.
