SURVEY FOR CENTRAL ENGINE OF PARSEC-SCALE HH JET


ABSTRACT

A jet (galactic jet, SS433 jet, YSO jet) is thought to be accelerated in the most inner region of the infalling disk. However, the mechanism of the acceleration is unknown. Our goal is TO DETECT THE ACTUAL SPOT OF ACCELERATION. We choose YSO jet as the target because the physical parameter of jet is obtained the most precisely. The central engine (protostar itself) has never been detected in the other wave length because of the high absorption (Av$>$100mag), but in the hard X-ray of ASCA we can detect. Our targets are Parsec-Scale HH jets for an analogy of 'Flare-Jet phenomena of R1(R CrA)'. Several targets have no driving source. Our second aim is TO DISCOVER THE DRIVING SOURCE. This will demonstrate the new capability of hard X-ray.
