What two things does a stars absolute magnitude depend?
Mass and age.
What is the expected main sequence lifetime of wolf 359 a very dim star having 10 percent of the suns mass?
Wolf 359, with about 10% of the Sun's mass, is classified as a red dwarf star. Such stars have very long main sequence lifetimes due to their low mass and efficient hydrogen-burning processes. The expected main sequence lifetime of Wolf 359 is estimated to be around 10 to 30 billion years, significantly longer than the Sun's approximate 10 billion-year lifetime. This longevity is a characteristic feature of low-mass stars.
How does hyddroststic equilibrium in a star is determined by mass?
Massive stars get hotter, burn their fuel faster, and therefore live shorter.With respect to their "death": Stars of "normal" mass become white dwarves; more massive stars become neutron stars, and the most massive stars become black holes.
What is the range of expected stars lifetime?
The highest-mass stars have the shortest lifetimes; a star 60 times as massive as the Sun is predicted to have a lifetime of only a few million years, and extremely massive stars like R136a1 have even shorter lifetimes. In contrast, small, cool, dim stars can burn for a very long time; the smallest red dwarf stars may last for a trillion years before burning out.
How long a star lives depends on?
The suns mass. More massive stars have much higher temperatures and pressures. Although they have a lot more fuel (hydrogen), it is consumed at a much higher rate than lower mass stars. They burn very brightly and hot, but for less time.
What dose the lifetime of a star depend on?
Mainly its mass. The most massive stars develop the most quickly.
How does a stars mass indicate its lifetime?
When a star is at the end of its lifetime its mass increases.
How does a stars mass indicate?
When a star is at the end of its lifetime its mass increases.
What are the remnants of a high mass star?
Massive stars become neutron stars, or black holes (depending on how much mass is left at the end of a star's lifetime).
Is the sun a low mass or high mass star?
There are more low mass stars. this is for two reasons:- # the star forming process generates more low mass stars # High mass stars burn out very quickly and explode as supernovas and thus over time there are less and less of them.
What two things does a stars absolute magnitude depend?
Mass and age.
Protostar will turn into what kind of star?
Protostars will eventually evolve into main sequence stars, where they will spend the majority of their lifetime fusing hydrogen into helium in their cores. The exact path of evolution will depend on factors such as mass, temperature, and composition.
What do stars have that depends on their size?
luminosity and temperature depend on their size but also on their mass
How does mass vary Along the main sequence?
Mass generally increases along the main sequence from low-mass stars like red dwarfs to high-mass stars like blue giants. This means that stars that are more massive are typically hotter, larger, and brighter than low-mass stars. Mass is a key factor that determines a star's temperature, luminosity, and lifetime.
How does a star's mass indicate lifetime?
When a star is at the end of its lifetime its mass increases.
Does smaller mass stars have a greater luminosity than larger mass stars?
This is not necessarily true. most of the time stars with a larger diameter have more mass but some stars with a smaller diameter are more dense and have a greater mass. Find a main sequence star chart and you can compare the data.
What does a stars life depend upon?
Its mass - the larger its mass the shorter its life.The smallest and least massive stars can last for trillions of years, whereas a massive star may end its life in millions of years.
