H91$\alpha$ Radio Recombination Line and 3.5 cm Continuum Observations of the Planetary Nebula NGC 3242 (2009)

Rodriguez, Luis F., Gomez, Yolanda, Lopez, J. Alberto, Garcia-Diaz, Ma. Teresa, Clark, David M.

We present high sensitivity H91$\alpha$ and 3.5 cm radio continuum observations toward the planetary nebula NGC 3242. The electron temperature determined assuming local thermodynamic equilibrium is...

Explosive Disintegration of a Massive Young Stellar System in Orion (2009)

Zapata, Luis A., Schmid-Burgk, Johannes, Ho, Paul T. P., Rodriguez, Luis F., Menten, Karl

Young massive stars in the center of crowded star clusters are expected to undergo close dynamical encounters that could lead to energetic, explosive events. However, there has so far never been...

The Rotating Molecular Structures and the Ionized Outflow Associated with IRAS 16547-4247 (2009)

Franco-Hernandez, Ramiro, Moran, James M., Rodriguez, Luis F., Garay, Guido

We present VLA 1.3 cm radio continuum and water maser observations as well as SMA SO$_2$ (226.300 GHz) and 1.3 mm dust continuum observations toward the massive star formation region IRAS 16547-4247....

VLBA determination of the distance to nearby star-forming regions III. HP Tau/G2 and the three-dimensional structure of Taurus (2009)

Torres, Rosa M., Loinard, Laurent, Mioduszewski, Amy J., Rodriguez, Luis F.

Using multi-epoch Very Long Baseline Array observations, we have measured the trigonometric parallax of the weak-line T Tauri star HP Tau/G2 in Taurus. The best fit yields a distance of 161.2 $\pm$...

The space distribution of nearby star-forming regions (2009)

Loinard, Laurent, Rodriguez, Luis F., Mioduszewski, Amy J.

Multi-epoch radio-interferometric observations of young stellar objects can be used to measure their displacement over the celestial sphere with a level of accuracy that currently cannot be attained...

A VLA Archive Observation of the Youngest Known Galactic Supernova Remnant G1.9+0.3 (2009)

Gomez, Yolanda, Rodriguez, Luis F.

We present the analysis of an unpublished VLA archive observation made at 1.49 GHz in 1989 toward the supernova remnant G1.9+0.3, the youngest such Galactic object known. This observation agrees with...

Radio Proper Motions of Wolf-Rayet Stars (2009)

Dzib, Sergio, Rodriguez, Luis F.

We present the analysis of observations taken from the Very Large Array archive of six Wolf-Rayet stars with radio emission, with the purpose of determining their proper motions. Typically, these...

High Angular Resolution Radio Observations of the HL/XZ Tau Region: Mapping the 50 AU Protoplanetary Disk around HL Tau and Resolving XZ Tau S into a 13 AU Binary (2009)

Carrasco-Gonzalez, Carlos, Rodriguez, Luis F., Anglada, Guillem, Curiel, Salvador

We present new 7 mm and archive 1.3 cm high angular resolution observations of the HL/XZ Tau region made with the VLA. At 7 mm, the emission from HL Tau seems to be arising in a clumpy disk with...

Large Scale Flows from Orion-South (2007)

Henney, W. J., O'Dell, C. R., Zapata, Luis A., Garcia-Diaz, Ma. T., Rodriguez, Luis F., Robberto, Massimo

Multiple optical outflows are known to exist in the vicinity of the active star formation region called Orion-South (Orion-S). We have mapped the velocity of low ionization features in the brightest...

Silicon Monoxide Observations Reveal a Cluster of Hidden Compact Outflows in the OMC1 South Region (2006)

Zapata, Luis A., Ho, Paul T. P., Rodriguez, Luis F., O'Dell, C. R., Zhang, Qizhou, Muench, August

We present high angular resolution ($2\rlap.{''}8 \times 1\rlap.{''}7$) SiO J=5$\to$4; $v=0$ line observations of the OMC1S region in the Orion Nebula made using the Submillimeter Array (SMA). We...

Stellar Winds and Embedded Star Formation in the Galactic Center Quintuplet and Arches Clusters: Multifrequency Radio Observations (2005)

Lang, Cornelia C., Johnson, Kelsey E., Goss, W. M., Rodriguez, Luis F.

A multi-frequency, multi-configuration study has been made of the compact radio sources in the Galactic Center Quintuplet and Arches stellar clusters using the Very Large Array. Ten radio sources...

PKS 1622-253: a weakly accreting, powerful gamma-ray source (2005)

Punsly, Brian, Rodriguez, Luis F., Tingay, Steven J., Cellone, Sergio A.

We discuss new deep radio observations of PKS 1622-253 and their implications for the energetics of the central engine that powers this strong high-energy gamma-ray source. Combining archival...
