Shock! The most important, most large stars aren’t all the time the most well liked.
To first turn into a star, your core should cross a important temperature threshold: ~4,000,000 Ok.
Such temperatures are required to provoke core fusion of hydrogen into helium.
Nonetheless, the encompassing layers diffuse warmth, capping photosphere temperatures at ~50,000 Ok.
Larger temperatures require extra evolutionary steps.
Your star’s core contracts and heats up upon exhausting its hydrogen.
Helium fusion then begins, injecting much more vitality.
Nonetheless, “crimson big” stars are fairly cool, increasing to decrease their floor temperatures.
Most crimson giants blow their outer layers away, revealing a heated, contracted core.
With white dwarf surfaces reaching ~150,000 Ok, they surpass even blue supergiants.
The very best stellar temperatures, nonetheless, are achieved by Wolf-Rayet stars.
Destined for cataclysmic supernovae, Wolf-Rayet stars are fusing the heaviest components.
They’re extremely advanced, luminous, and surrounded by ejecta.
The most popular one measures ~210,000 Ok; the most well liked recognized star.
The remnant cores of supernovae can kind neutron stars: the most well liked objects of all.
With preliminary inside temperatures cresting ~1 trillion Ok, they radiate warmth rapidly.
After mere years, their surfaces cool to ~600,000 Ok.
Regardless of all we’ve found, neutron stars stay the most well liked and densest particular person objects recognized.
