Black holes keep ‘burping up’ stars they destroyed years earlier, and astronomers don’t know why::Years after ripping stars to shreds, 24 black holes suddenly flared up with radio waves in inexplicable ‘burping’ bouts. Half of all star-killing black holes may experience the same.

As far as i know the Mass of the black Hole is concentrated in the Center (singularity). But it is surouded by its schwarzschild Radius. Anything that enters it cant escape.
