Is it possible to determine, through gravity wave analysis alone if the stellar remnant is a neutron star or a black hole?
Hi Patrick Good Day or Evening ,
According to the link below Betelgeuse and its about 17.5 M ☉ would become a neutron star. It really is a bit early regarding gravity wave analysis to determine what happened, but the burst was short. The first one that was detected was in 2015 and it was a black hole merger.
Here is the sound of the first Gravity Wave ever a Black Hole Merger.
Here is the sound from a gravity wave with a neutron star merger. Now realize a star that goes Supernova and turns into a Neutron star is different as in possibly Betelgeuse.
