VLA Observations of Z CMa: The Orientation and Origin of the Thermal Jet
We present sensitive, high angular resolution ( 0``45) Very Large Arrayobservations made at 6 and 3.5 cm toward the thermal jet associated with theyoung star Z CMa. We found that the position angle of the axis of the thermal jetis coincident within error with the orientation of the optical jet and t...

| Sumario: | We present sensitive, high angular resolution ( 0``45) Very Large Arrayobservations made at 6 and 3.5 cm toward the thermal jet associated with theyoung star Z CMa. We found that the position angle of the axis of the thermal jetis coincident within error with the orientation of the optical jet and the orientationof the CO bipolar outflow. The faint radio features detected around this young star(mostly to its east) are probably the result of periodic material ejection from thecentral source. It is known that Z CMa has an infrared companion about 0:001 toits northwest. We have used our high angular resolution ( 0``2) A configurationdata and the astrometric position from Hipparcos to establish that the jet originatesfrom the optical component of this binary. |
