ALMA and VLA observations of the outflows in IRAS 16293-2422
Laurent Loinard, Luis A. Zapata, Luis F. Rodriguez +10
We present ALMA and VLA observations of the molecular and ionized gas at 0.1-0.3 arcsec resolution in the Class 0 protostellar system IRAS 16293-2422. These data clarify the origin…
Early stages of cluster formation: fragmentation of massive dense cores down to ~1000 AU
Aina Palau, Asunción Fuente, Josep M. Girart +11
In order to study the fragmentation of massive dense cores, which constitute the cluster cradles, we observed with the PdBI in the most extended configuration the continuum at 1.3…
Mid-J CO emission from the Orion BN/KL explosive outflow
T. -C. Peng, L. A. Zapata, F. Wyrowski +2
High spatial resolution low-J 12CO observations have shown that the wide-angle outflow seen in the Orion BN/KL region correlates with the famous H2 fingers. Recently, high-resoluti…
Radio and Optical Observations of DG Tau B
Luis F. Rodríguez, Sergio A. Dzib, Laurent Loinard +4
DG Tau B is a Class I young stellar source that drives the asymmetric HH 159 bipolar jet. At optical wavelengths it is obscured by circumstellar optically-thick material. Using VLA…
ALMA observations of the outflow from the Source I in the Orion-KL region
Luis A. Zapata, Luis F. Rodriguez, Johannes Schmid-Burgk +3
In this {\it Letter}, we present sensitive millimeter SiO (J=5-4; =0) line observations of the outflow arising from the enigmatic object Orion Source I made with the Atacama Lar…
From dusty filaments to massive stars: The case of NGC 7538 S
Raul Naranjo-Romero, Luis A. Zapata, Enrique Vazquez-Semadeni +3
We report on high-sensitivity and high-angular resolution archival Submillimeter Array (SMA) observations of the large (15000 AU) putative circumstellar disk associated with…
