A main sequence star of less than 8 solar masses ends its life as a?
A white dwarf.
Why is there a lower mass limit of 0.08 solar-masses for main-sequence stars?
Below about 0.08 solar masses an object will not be able to ignite nuclear fusion. There may be small amounts of deuterium fusion, but it is not sustainable. Objects between 0.08 solar masses and about 13 Jupiter masses are called brown dwarfs.
If a star was 150 solar masses what would its lifetime be?
A star that was 150 solar masses would spend the main part of its life as a main sequence star before collapsing into a white dwarf. A stars mass determines the life expectancy as well as its probable cause of death.
Why is there an upper mass limit for main-sequence stars of about 100 solar masses?
Objects above this mass fuse hydrogen too rapidly and cannot stay together.
How long would main sequence star last if twice as massive as the sun?
A star with a mass of 2solar masses, 2times the mass of the sun, would have a main-sequence stage of half the life of a star with the mass of our sun. More massive stars die faster, less massive stars live longer and therefore have longer main-sequence stages.
A main sequence star of less than 8 solar masses ends its life as a?
A white dwarf.
What star has a temperature in the 3000 degrees?
It is a main sequence star of class M. It can range in size form 0.08 to 0.45 solar masses, and a radius of less than 0.7 times that of the sun. A majority (76%) of main sequence stars belong to this category.
What current stage of stellar evolution is Sirius?
Sirius consists of two stars.Sirius A is a main-sequence star with about two solar masses.Sirius B is a white dwarf with about one solar mass. During its main-sequence, it's estimated to have been around five solar masses.

What sequence best describes the formation and elevation of stars with masses similair to the sun?
The Main Sequence
What properties do red main sequence stars share?
high masses low tempature
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.

A star with a mass of 2solar masses, 2times the mass of the sun, would have a main-sequence stage of half the life of a star with the mass of our sun. More massive stars die faster, less massive stars live longer and therefore have longer main-sequence stages.
How many stars are in our solar system and what type?
There is one star in our solar system: the sun. It is a yellow main sequence star.
What color is the most massive type of mainsequence star?
The most massive type of main sequence star on the HR diagram would be indicated by the main sequence area at the top left of the HR diagram, which would be blue or violet in color. Zeta Puppis is an example of such a star. It comes in at 40 solar masses. It is classified as a type "O" star.
