What happens in the main sequence of a star?

What happens in the main sequence of a star?

Main sequence stars fuse hydrogen atoms to form helium atoms in their cores. Stars start their lives as clouds of dust and gas. Gravity draws these clouds together. A small protostar forms, powered by the collapsing material.

How do stars on the main sequence generate their energy quizlet?

They actually are fairly bright but appear dark against the even brighter background of the surrounding Sun. How do main-sequence stars generate energy? the nuclear fusion of hydrogen into helium. Which element has the lowest mass per nuclear particle and therefore cannot release energy by either fusion or fission?

How do stars on the main sequence obtain their energy?

Main sequence stars provide their energy by fusing hydrogen atoms together to produce helium. The more massive a star is, the more energy it requires to counteract its own gravity.

How do main sequence stars generate energy?

Main sequence stars produce energy by fusing hydrogen into helium.

How does a main-sequence star generate energy?

What is main-sequence star quizlet?

Main sequence stars are stars that are fusing hydrogen atoms to form helium atoms in their cores. A pulsar is a core of neutrons (neutron star) that remain after a supernova and emit rapidly varying sources of low-frequency radio waves.

What is a main sequence star quizlet?

Main sequence stars are stars that are fusing hydrogen atoms to form helium atoms in their cores. Gas ejected from a low-mass star in the final stage of its life.

Why are most stars found in the main sequence?

So why, then, do most stars seem to lie on the main sequence? So, broadly speaking, there are so many stars on the main sequence – compared to elsewhere in the H-R diagram – because stars spend much more of their lives burning hydrogen in their cores than they do producing energy in any other way!

What is a main-sequence star quizlet?

Why is there a main sequence quizlet?

Main sequence is when a star is burning hydrogen in its core. The luminosity and temperature of a main-sequence star are set by its mass.

What determines the location of a star on the main sequence quizlet?

Mass determines where on the main sequence a star lives, and what the main sequence lifetime is for the star.

What determines if a star is on the main sequence quizlet?
