What two things does a stars absolute magnitude depend?
Mass and age.
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.
Which of the following are the best candidates to search for planets that might harbor extraterrestrial life?
Solar-mass stars because they have both a large habitable zone and a long stellar lifetime.
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.
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 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).
What two things does a stars absolute magnitude depend?
Mass and age.
What do stars have that depends on their size?
luminosity and temperature depend on their size but also on their mass
What does the life span of a star depend on?
How massive it is and its luminosity (the mass and luminosity correlate with each other with most stars, mainly the main sequence stars). The more mass a star has, the shorter its lifespan.
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.
How does a star's mass indicate lifetime?
When a star is at the end of its lifetime its mass increases.
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.
How long does an massive star live?
The lifetime of a star varies a lot, depending on its exact mass. The lifetime of a star can be anywhere from just a few million years for the most massive stars, to trillions of years for red dwarves.
