After Vulcan killed corsair Havok took his place, did marvel ever follow up on this?
I just checked with wikipedia, because I didn't actually know, ha ha.
"Havok along with Polaris, Rachel, Korvus, Ch'od, and Raza form a new team of Starjammers after the death of Corsair, dedicated to defeating Vulcan and restoring Lilandra to the throne."

Is that what you are looking into?
...they then fought Vulcan until Black Bolt killed Vulcan. They then came home and Havok joined X-Factor for a minute. Then he joined the Avengers Unity team for awhile then Axis happened and he rejoined Cyclop's X-men. As for the Starjammers, they went back to space and were ran by Ch'od and Raza for awhile before Corsair turned up alive somehow.
So more specifically, the followup was in a 5-issue miniseries called "X-Men: Emperor Vulcan" by Christopher Yost and Paco Diaz from 2007-2008, and then the stuff with Blackbolt and Vulcan came happened in the Dan Abnett/Andy Lanning event comic miniseries "War of Kings".
