PX282 - E7 - remnants

a mass of remnant material is left

for a star of mass less than $25M_{\odot }$, a neutron star remains

they are supported by neutron degeneracy pressure

the maximum mass is given by the chandrashekhar limit of $\sim 3M_{\odot }$

typically, they are $1.4M_{\odot }$

if the initial star is much more massive, a blackhole is obtained
