Infall and rotation motions in the HH 111 protostellar system: A flattened envelope in transition to a disk?
Chin-Fei Lee, Yao-Yuan Mao, Bo Reipurth
We have mapped the central region of the HH 111 protostellar system in 1.33 mm continuum, C18O(J=2-1), 13CO (J=2-1), and SO (N_J=5_6-4_5) emission at ~3" resolution with the Submil…
Visual Binaries in the Orion Nebula Cluster
Bo Reipurth, Marcelo M. Guimarães, Michael S. Connelley +1
We have carried out a major survey for visual binaries towards the Orion Nebula Cluster using HST images obtained with an H-alpha filter. Among 781 likely ONC members more than 60"…
Infrared Nebulae Around Young Stellar Objects
Michael S. Connelley, Bo Reipurth, Alan T. Tokunaga
We present a K-band atlas of 106 reflection nebulae, 41 of which are new discoveries. We observed these nebulae with the UH 2.2 m telescope in the course of an imaging survey of 19…
Anatomy of HH 111 from CO observations : a bow shock driven molecular outflow
B. Lefloch, J. Cernicharo, B. Reipurth +2
We present millimeter line observations of the HH 111 outflow and its driving source. The molecular gas emission observed with IRAM 30m and the CSO reveals a small condensation of…
