comment What is brighter/more powerful, a gamma ray burst or a supernova?
Voted to close because the question is so general and imprecise that I suspect that even just writing the GRB or the SN would be accepted lol

comment Is the Drake Equation an accurate way of finding the probability of life on planets?
Let's see we can address you instead of giving just an answer: what is the Drake equation used for?

comment Is it possible to break apart a neutron star?
this does not have anything to do with the OP question :) 'Peeling apart' is referred to 'showing the shells' of the NS. You could consider to remove this answer.

Perhaps accreting matter until TOV limit is reached?

That reference says (dex), and you can obtain 8% only by decimal logarithm.

comment Star class according to initial mass
Yes indeed, if only the OP would add more details to the question...

comment Star class according to initial mass
I am not sure to understand the question. Are you in doubt about WHY the star changes its spectral classification?

comment Star class according to initial mass
Roman number is not related to the spectral type (G,M, etc), but to the luminosity class, see here: img.bhs4.com/89/9/…

Do you mean the luminosity class?

comment Can we see individual stars in other galaxies?
A supernova is a process, an event, not an object. Supernova Remnants are objects.
