The SiO outflow from IRAS 17233-3603 at high resolution
P. D. Klaassen, K. G. Johnston, S. Leurini +1
Context: Jets and outflows are key ingredients in the formation of stars across the mass spectrum. In clustered regions, understanding powering sources and outflow components poses…
ALMA reveals a candidate hot and compact disk around the O-type protostar IRAS 165474247
Luis Zapata, Aina Palau, Roberto Galvan-Madrid +4
We present high angular resolution ( 0.3) submillimeter continuum (0.85 mm) and line observations of the O-type protostar IRAS 165474247 carried out with the Atacama La…
Hot Ammonia around Young O-type Stars. II. JVLA imaging of highly-excited metastable ammonia masers in W51-North
Ciriaco Goddi, Christian Henkel, Qizhou Zhang +2
We have used the JVLA at the 1 cm band to map five highly-excited metastable inversion transitions of ammonia, (J,K)=(6,6), (7,7), (9,9), (10,10), and (13,13), in W51 IRS2 with ~0.…
Kinematics of the Outflow From The Young Star DG Tau B: Rotation in the vicinities of an optical jet
Luis A. Zapata, Susana Lizano, Luis F. Rodriguez +4
We present CO(2-1) line and 1300 m continuum observations made with the Submillimeter Array (SMA) of the young star DG Tau B. We find, in the continuum observations, emis…
An Ionized Outflow from AB Aur, a Herbig Ae Star with a Transitional Disk
Luis F. Rodriguez, Luis A. Zapata, Sergio A. Dzib +4
AB Aur is a Herbig Ae star with a transitional disk. Transitional disks present substantial dust clearing in their inner regions, most probably because of the formation of one or m…
IC348-SMM2E: a Class 0 proto-brown dwarf candidate forming as a scaled-down version of low-mass stars
Aina Palau, Luis A. Zapata, Luis F. Rodriguez +7
We report on Submillimeter Array observations of the 870 micron continuum and CO(3-2), 13CO(2-1) and C18O(2-1) line emission of a faint object, SMM2E, near the driving source of th…
