Beschreibungen/Notizen

• We present Magellan adaptive optics H imaging of HH 508, which has the highest surface brightness among protostellar jets in the Orion Nebula. We find that HH 508 actually has a shorter component to the west, and a longer and knotty component to the east. The east component has a kink at 0 3 from the jet-driving star θ1 Ori B2, so it may have been deflected by the wind/radiation from the nearby θ1 Ori B1B5. The origin of both components is unclear, but if each of them is a separate jet, then θ1 Ori B2 may be a tight binary. Alternatively, HH 508 may be a slow-moving outflow, and each component represents an illuminated cavity wall. The ionization front surrounding θ1 Ori B2B3 does not directly face θ1 Ori B1B5, suggesting that the EUV radiation from θ1 Ori C plays a dominant role in affecting the morphology of proplyds even in the vicinity of θ1 Ori B1B5. Finally, we report an H blob that might be ejected by the binary proplyd LV 1.
