| Some can produce black holes as end products | To achieve hydrostatic equilibrium, massive stars will use up their supply of hydrogen more quickly and live a shorter life |
|---|---|
| One of a series of such transient disturbances, usually recurring at regular intervals and having a characteristic geometric shape | Eventually, the core of the star will run out of fusible material |
This is a spectral class of stars that has two intrinsic properties; in fact has two main things to do: Firstly, it keeps on bombarding and flashing the Earth with very powerful beams of light.
2| The pulsar emits incredibly intense high-energy gamma rays, which the researchers detected and studied using NASA's Fermi Gamma-Ray Space Telescope | When a star becomes a supernova and explodes, it can leave behind a rapidly spinning neutron star about 20 miles across rotating up to 30 times per second |
|---|---|
| Because they are so massive, class O stars have very hot cores, thus burn through their hydrogen fuel very quickly, and so are the first stars to leave the | Every time one of the poles of the neutron star crosses our line of sight, we see a pulse of radiation like a lighthouse beacon |
At the place where the zero-age main sequence for hydrogen burning stars H-ZAMS and the supergiant branch come together, we find the earliest bluest, hottest.
