Where does a star spend most of its life on an hr diagram?
On the main sequence.
What category does a star belong in Main sequence star white dwarf red giant neutron star?
None of those is a main sequence star.
What is the nearest star in the main sequence is?
Most stars are on the main sequence; that includes red dwarves. Specifically, in this case, the closest known star - Proxima Centauri - is also the closest main-sequence star.
Is a neutron star on the main sequence?
A neutron star is a stellar remnant and is no longer on the main sequence. See related questions.
At what stage in star development does a star spend most of its life?
A Star spends most of its life on the "main sequence" of the Hertzsprung-Russell diagram (see related link below). While here it is called a "main sequence" star and its source of energy during this phase of its life is the fusion of hydrogen into helium in its core.
How long does an average star spend as a hydrogen- burning main sequence star?
Ten billion years
Will a star spend most of its life as a protostar?
No, it will spend most of it's life as a main sequence star.
Where does a star spend most of its life on an hr diagram?
On the main sequence.
How does the main-sequence lifetime of a star compare to its entire fusion lifetime?
Stars spend about 90% of their fusion lifetimes on the main sequence.
Where does a star spend most of its lifetime on the h-r diagram?
On the main sequence.
Do Stars spend most of their life span as main-sequence stars?
Yes Star spend most of their life span as a main sequence star. A star end will depend on its size in life the end of a start can be a red giant to supernova, a white dwarf, pulsar, or black hole.
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.
Where does a star spend most of its lifetime on an h r diagram?
MAIN-SEQUENCE The average star spends 90% of its life as a hydrogen burning MS star.
Is a red giant star considered to be a main sequence star?
No. Red giants are not on the main sequence.
Does a red main sequence star have fusion?
A red main sequence star would be a red dwarf or a branch red giant. To be on the main sequence, you have to have hydrogen nuclear fusion.
Name an example of a main sequence?
The sun is a main sequence star
Main sequence star distance from earth?
The sun is a main sequence star, so 1 AU.
