You can age a star prematurely by adding more heavy element mass to it. Add
anything above helium, as much as possible, and this will age a star. Dropping a
black hole quickly through the center of a star will make it YOUNGER, because
more of the heavy elements will be at the core, so when the black hole passes
through the star it will eat a tunnel through the star, sucking up a greater
proportion of the heavy element mass. However putting a black hole on a
trajectory that allows it to touch down at the surface at a low enough speed for
the drag induced by the corona to decay its orbit will likely trigger a
supernovae, but probably a more powerful one that will have a significant GRB
component.
