Narrative:

We were inbound to beuty intersection on the milton arrival at 10;000 feet/300 KIAS as assigned by new york center. Radio traffic indicated that there was a parachute jump aircraft in the vicinity of beuty at 12;500 feet VFR. He was in communications with new york center. As we approached the intersection; the pilot of the jump aircraft announced that his jumpers were away and asked center for instructions to begin his spiral down. At this point I noted a traffic alert hit on the jump aircraft at 12 o'clock; inside of 2.5 miles and 1;600 feet above us. The next hit which was mere seconds later was +200 and less than 1 mile. At this point I acquired the aircraft visually and he appeared to be rolling out at our 12 o'clock position and co-altitude; opposite direction. I immediately disconnected the autopilot and began an aggressive climbing right turn to avoid a midair. As I did so we received a 2000ft/min climb RA. As I complied with the RA; the pilot monitoring announced our TCAS climb to ATC. At our nearest point; it appeared our aircraft came within 100 feet altitude and 1/2 mile laterally. In my estimation; a midair would've most likely occurred without our evasive action. New york center was advised of our intent to file this report and I advised the [company] upon landing so that other inbound aircraft would be made aware of the threat on the milton arrival.
