Procedure; Environment - Non Weather Related
Our flight was on a vector heading to 320 degrees assigned; descending from 12;000 to 8;000 MSL on the TYSSN 3 to LAS. A [widebody transport] was ahead and lower; approximately 8 miles ahead. While descending; encountered wake turbulence in still air. Aircraft rolled approximately 50 degrees bank with autopilot engaged. Aircraft was in a right turn to begin with and descending to an assigned altitude; 8;000 MSL. TRACON then advised of wake turbulence. I responded that we encountered wake turbulence upset. TRACON leveled our flight at 9;000 MSL. We proceed to a visual approach to Runway 19R without further incident.
A CE-560 pilot reported a wake vortex encounter inbound to LAS 8 miles in trail of a widebody aircraft that resulted in a 50 degree roll.
