The distance to SS433/W50 and its interaction with the interstellar medium.
LOCKMAN F.J., BLUNDELL K.M. and GOSS W.M.
Abstract (from CDS):
This Population I system, now about 200 pc below the Galactic plane, most likely originated as a runaway O-star binary ejected from a young cluster in the plane. Given a modest ejection velocity of ≥30 km/s, the binary could have reached its present location in ≤10 Myr at which time the more massive member became a supernova (SN). New astrometric data on SS433 show that the system now has a peculiar velocity of a few tens of km/s in the direction of the Galactic plane. From this peculiar velocity and the symmetry of the W50 remnant, we derive a time since the SN of ≤1x105 yr.
