Narrative:

While descending via the STAR; we were called out as traffic to aircraft Y that had dropped its jumpers and was descending steeply back to their airport to the east of our arrival corridor. The aircraft was not called out to us as traffic but both the first officer and myself had the aircraft in sight and determined its path not to be a threat to our flightpath. As the cessna descended through our altitude; making counter-clockwise turns; we received a TCAS RA to 'level off' and the first officer disconnected the automation and leveled the aircraft at approximately 8;000 ft. I communicated our response to the RA to the approach controller and within seconds of leveling off the RA extinguished and we resumed descending on the arrival without further incident.aircraft descending VFR in close proximity to arrival corridor caused our TCAS to issue a RA. At no time did the approach controller alert us to the position of this aircraft; though both pilots had the cessna in sight; and the controller never indicated to the cessna that they should move away from the arrival corridor. Approach should more actively separate skydive aircraft from the STAR course when aircraft are descending on the arrival.
