Is the sun a low mass or high mass star and which stage is it in?
The sun is a low mass star in the main sequence stage of its life cycle.
Is the sun a lower mass star or a higher mass star and which stage is it in?
The sun is considered a lower mass star. It is currently in the main sequence stage of its life cycle, where it fuses hydrogen into helium in its core.
Which type of star best obey mass-luminosity relation?
Main sequence stars best obey the mass-luminosity relation. This empirical relation states that there is a direct relationship between a star's mass and its luminosity. In general, the more massive a main sequence star is, the more luminous it will be.
What will a high mass protostar turn into?
A high mass protostar will eventually evolve into a massive star like a red supergiant, followed by a supernova explosion. After the supernova event, the remnants may form a neutron star or a black hole.
Which property of a main-sequence star gradually decreases throughout the star's life?
Mass of hydrogen
Is the sun a low mass or high mass star and which stage is it in?
The sun is a low mass star in the main sequence stage of its life cycle.
A solar mass star will evolve off the main sequence when?
A solar mass star will evolve off the main sequence when it exhausts its core hydrogen fuel and transitions to burning helium in its core. This change in nuclear fusion process causes the star to expand and become a red giant as it moves towards the later stages of its evolution.
Will the K-type Epsilon Eridani star eventually evolve into a G-type main sequence star like the Sun?
No. A star's class on the main sequence is ultimately predetermined by its mass, so a star cannot change its position on the main sequence. Epsilon Eridani is about 82% the mass of the sun, which limits it to a lower rate of fusion and thus a lower temperature and luminosity than a G-type star like the sun. Epsilon Eridani's only change in class will come when it leaves the main sequence to become a red giant.
Is the sun a lower mass star or a higher mass star and which stage is it in?
The sun is considered a lower mass star. It is currently in the main sequence stage of its life cycle, where it fuses hydrogen into helium in its core.
Is Sirius A a main sequence star?
Polaris - the current North star is a multiple star system., consisting of the main star and smaller companions. The main star Alpha Ursae Minoris is a bright star, a 6 solar mass supergiant and it is a main sequence star. Orbiting very close to this main star is a white dwarf of roughly 1.5 solar masses. This is not a main sequence star. Orbiting further out is the third companion, a 1.39 solar mass star. This is a main sequence star. There are also two more distant components (α UMi C and α UMi D) - Polaris is thought to be part of an open cluster - I do not know if these later two stars are main sequence or not.
What is the main predictor of where a star will spend most of the time on the main sequence and why?
The star's mass. More mass will make the star hotter, and will increase the pressure in the center; this will make the star burn its fuel faster.When a star is on the "main sequence", it burns hydrogen-1, converting it into helium-4.
Is the sun a low mass or high mass sequence star?
The sun is a low mass sequence star. It is classified as a G-type main-sequence star, which means it is in the middle of its stellar evolution and will remain stable for billions of years.
Which type of star best obey mass-luminosity relation?
Main sequence stars best obey the mass-luminosity relation. This empirical relation states that there is a direct relationship between a star's mass and its luminosity. In general, the more massive a main sequence star is, the more luminous it will be.
Is the main sequence lifetime of a low mass star the same as the lifetime of the sun?
No. The less massive a star, the longer it will last. A main sequence star half the mass of the sun can be expected to last about 5 times longer.
Is a white dwarf considered a main sequence star?
No, a white dwarf is not considered a main sequence star. Main sequence stars are stable stars that are fusing hydrogen into helium in their cores, while white dwarfs are the remnants of low to medium mass stars after they have exhausted their nuclear fuel.
What will a high mass protostar turn into?
A high mass protostar will eventually evolve into a massive star like a red supergiant, followed by a supernova explosion. After the supernova event, the remnants may form a neutron star or a black hole.
Which property of a main-sequence star gradually decreases throughout the star's life?
Mass of hydrogen
