Is the sun a lower mass star or a higher mass star and which stage is it in?
The Sun is a medium mass star on the main sequence.
Is the sun a low mass or high mass star and which stage is it in?
The Sun is a medium mass star in main sequence.
Which property of a main-sequence star gradually decreases throughout the star's life?
Mass of hydrogen
What will a high mass protostar turn into?
A protostar is the first building block of the main star. As it has not yet accumulated enough mass to join the main sequence, it will be smaller than the main star. The next stage will be a T Tauri star.
Which type of star best obey mass-luminosity relation?
Main sequence stars
A solar mass star will evolve off the main sequence when?
it builds up a core of inert helium.
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.
How can you find the luminosity of a main sequence star?
it depends on the mass of the star.
Is the sun a lower mass star or a higher mass star and which stage is it in?
The Sun is a medium mass star on the main sequence.
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.
Is the sun a low mass or high mass star and which stage is it in?
The Sun is a medium mass star in main sequence.
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 a white dwarf considered a main sequence star?
No, a white dwarf is not considered a main sequence star. A main sequence star is a star that is still fusing hydrogen in its core. A white dwarf is the remnant of a low to medium mass star in which fusion has stopped.
How long does it take for a star like the Sun to evolve from the main sequence to the top of the red giant branch?
A star like the sun is a slow evolving star. It is estimated that it will take about ten million years for it to evolve from the main sequence to the top of the giant red branch.
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.
How can you explain the Algol paradox?
In some binary systems, the less-massive star has become a giant, while the more-massive star is still on the main sequence. If higher-mass stars evolve faster than lower-mass stars, how do the lower-mass stars in such binaries manage to leave the main sequence first? This is called the Algol paradox, after the binary system Algol.
Which property of a main-sequence star gradually decreases throughout the star's life?
Mass of hydrogen
