ALMA Observations of the Extraordinary Carina Pillars: HH 901/902
Geovanni Cortes-Rangel, Luis A. Zapata, Jesus A. Toala +4
We present Atacama Large Millimeter/Submillimeter Array (ALMA) 1.3 mm continuum and CO(21), ND(32), CS(54), and CO(21) line sensitive and…
The initial physical conditions of the Orion BN/KL fingers
Pedro Ruben Rivera-Ortiz, Ary Rodríguez-González, Liliana Hernández-Martínez +2
Orion BN/KL is an example of a poorly understood phenomena in star forming regions involving the close encounter of young stellar objects. The explosive structure, the great variet…
APEX Millimeter Observations of Methanol Emission Toward High-Mass Star-Forming Cores
Vicente Hernández-Hernández, Stan Kurtz, Sergei Kalenskii +4
We present 247-GHz molecular line observations of methanol (CHOH) toward sixteen massive star-forming regions, using the APEX telescope with an angular resolution of . Th…
G5.89: An Explosive Outflow Powered by a Proto-Stellar Merger?
Luis A. Zapata, Paul T. P. Ho, Estrella Guzman-Ccolque +6
The explosive outflows are a newly-discovered family of molecular outflows associated with high-mass star forming regions. Such energetic events are possibly powered by the release…
On the nature of the compact sources in IRAS 16293-2422 seen in at centimeter to sub-millimeter wavelengths
Antonio Hernández-Gómez, Laurent Loinard, Claire J. Chandler +10
We present multi-epoch continuum observations of the Class 0 protostellar system IRAS 16293-2422 taken with the Very Large Array (VLA) at multiple wavelengths between 7 mm and 15 c…
An Asymmetric Keplerian Disk Surrounding the O-type Protostar IRAS165474247
Luis A. Zapata, Guido Garay, Aina Palau +4
During the last decades, a great interest has emerged to know if even the most massive stars in our galaxy (namely the spectral O-type stars) are formed in a similar manner as the…
