In the death of a high mass star, which of the following occurs on the timescale of hours?
a. formation of supernova
b. remnant neutronization
c. propagation of the shockwave to surface of star
d. photodisintegration



Answer :

Answer:

c. propagation of the shockwave to the surface of star

In the death of a high-mass star, the shockwave reaching the surface occurs within hours.

Explanation:

  1. The collapse of the core in the death of a high-mass star leads to a series of events, including the formation of a neutron star and a supernova explosion. The shockwave from the rebounding core propagates to the surface of the star within a few hours.
