Stellar Evolution Type II Supernova

Massive stars end in explosive brilliance, scattering elements that build worlds

0

Why do Type II supernovae predominantly occur in spiral galaxies rather than elliptical galaxies?

Because elliptical galaxies have more hydrogen in their stars, preventing supernova explosions. Because spiral galaxies have young, massive stars necessary for Type II supernovae, while elliptical galaxies mostly contain older, low-mass stars. Because Type II supernovae only occur in isolated stars outside of galaxies.

Stellar Evolution Type II Supernova

Massive stars explode with hydrogen signatures, reshaping galaxies and seeding new stars

0

What key factor distinguishes a Type II supernova from other supernova types and influences where it is typically observed?

The absence of hydrogen and its occurrence mainly in elliptical galaxies It occurs only in stars less massive than the Sun and is common in all galaxy types The presence of hydrogen in its spectrum and its occurrence in regions with young, massive stars
