Resolving the Structure and Kinematics of the BN Object at Resolution
Luis F. Rodríguez, Luis A. Zapata, Paul T. P. Ho
We present sensitive 7 mm observations of the H53 recombination line and adjacent continuum, made toward the Orion BN/KL region. In the continuum we detect the BN object, the ra…
An Extensive, Sensitive Search for SiO Masers in High- and Intermediate-Mass Star-Forming Regions
Luis A. Zapata, Karl Menten, Mark Reid +1
We present sensitive Very Large Array observations with an angular resolution of a few arcseconds of the line of SiO in the =1 and 2 vibrationally excited states towa…
Unveiling a Compact Cluster of Massive and Young Stars in IRAS 17233-3606
Luis A. Zapata, Silvia Leurini, Karl M. Menten +3
We have analyzed sensitive high spatial resolution archival radio continuum data at 1.3, 2.0, 3.6 and 6.0 cm as well as the H2O maser molecular line data obtained using the Very La…
High mass star formation in the IRAS 17233-3606 region: a new nearby and bright hot core in the southern sky
S. Leurini, C. Hieret, S. Thorwirth +5
We present molecular line observations of the massive star forming region IRAS 17233-3606 aimed at studying the molecular core associated with the source. The observations were mad…
Forming an Early O-type Star Through Gas Accretion?
Luis A. Zapata, Aina Palau, Paul Ho +4
We present high angular resolution ( 3) and sensitive 1.3 mm continuum, cyanogen (CN) and vinyl cyanide (CHCN) line observations made with the Submillimeter Array…
A dense micro-cluster of Class 0 protostars in NGC 2264 D-MM1
Paula S. Teixeira, Luis A. Zapata, Charles J. Lada
We present sensitive and high angular resolution (~1") 1.3 mm continuum observations of the dusty core D-MM1 in the Spokes cluster in NGC 2264 using the Submillimeter Array. A dens…
