The life of a star is governed by how much mass it has and how quickly it "burns" it.
A basic formula is 1exp10*(m/l) where m=Sol mass and l=Sol luminosity.
So for our Sun 1exp10*(1/1) gives 10 billion years.
Suns
No, stars are not habitable for life as we know it. Stars are massive balls of gas undergoing nuclear fusion, producing high temperatures and radiation that are inhospitable to life. Planets orbiting stars can be habitable depending on their distance from the star and other factors.
Yes, iron is present in stars. Iron is formed in the cores of stars through nuclear fusion processes and is an important element in the life cycle of stars. When a star reaches the end of its life and goes supernova, iron is released into space, where it can be recycled into new stars and planets.
The stars in the sky are very much like our Sun.
They can be. Stars are very hot and can emit harmful amounts of radiation. At the same time, without stars there would be no life.
No; stars are not, to the best of our knowledge, "alive".
The formula is just n.
No, but some stars end their life by becoming a black hole.
stars live for about ten billionyears
how can you claimed formula and calculation in your life
Stars are suns and cannot sustain life. Earth is well, earth, and it CAN sustain life.
The massive stars turn into gas
Suns
10 billion years or less if stars collide
Nothing that we know of can survive the heat generated on surface of stars, therefore, no. Planets could carry life forms.
