On the Effects of Self-Obscuration in the (Sub-)Millimeter Spectral Indices and Appearance of Protostellar Disks
Roberto Galván-Madrid, Hauyu Baobab Liu, Andrés F. Izquierdo +5
In this paper we explore the effects of self-obscuration in protostellar disks with a radially decreasing temperature gradient and a colder midplane. We are motivated by recent rep…
Resolving the Structure and Kinematics of the Youngest HII Regions and Radio Jets from Young Stellar Objects
Roberto Galván-Madrid, Maite Beltrán, Adam Ginsburg +4
In this contribution we explore the new science that a Next Generation Very Large Array (ngVLA) would be able to perform on the topics of the youngest HII regions and (proto)stella…
Magnetic fields in forming stars with the ngVLA
Charles L. H. Hull, Carlos Carrasco-González, Peter K. G. Williams +4
The magnetic field plays an important role in every stage of the star-formation process from the collapse of the initial protostellar core to the star's arrival on the main sequenc…
Broadband radio spectro-polarimetric observations of high Faraday rotation measure AGN
Alice Pasetto, Carlos Carrasco-González, Shane O'Sullivan +5
We present broadband polarimetric observations of a sample of high Faraday rotation measure (RM) AGN using the VLA telescope from 1 to 2 GHz, and 4 to 12 GHz. The sample (14 source…
JVLA Wideband Polarimetry Observations on a Sample of High Rotation Measure Sources
Alice Pasetto, Carlos Carrasco-González, Gabriele Bruni +4
We present preliminary results of JVLA wideband full polarization observations of a sample of Active Galactic Nuclei (AGN) with very high Rotation Measure (RM) values, a sign of ex…
Momentum-driven outflow emission from an O-type YSO: Comparing the radio jet with the molecular outflow
A. Sanna, L. Moscadelli, R. Cesaroni +3
Aims: We want to study the physical properties of the ionized jet emission in the vicinity of an O-type young stellar object (YSO), and estimate how efficient is the transfer of en…
SMA observations towards the compact, short-lived bipolar water maser outflow in the LkHα 234 region
J. M. Girart, J. M. Torrelles, R. Estalella +8
We present Submillimeter Array (SMA) 1.35 mm subarcsecond angular resolution observations toward the LkHα 234 intermediate-mass star-forming region. The dust emission arises from a…
An extremely high velocity molecular jet surrounded by an ionized cavity in the protostellar source Serpens SMM1
Charles L. H. Hull, Josep M. Girart, Lars E. Kristensen +6
We report ALMA observations of a one-sided, high-velocity (80 km s) CO() jet powered by the intermediate-mass protostellar source Serpens SMM1-a.…
Constraints on photoevaporation models from (lack of) radio emission in the Corona Australis protoplanetary disks
Roberto Galván-Madrid, Hauyu Baobab Liu, Carlo Felice Manara +8
Photoevaporation due to high-energy stellar photons is thought to be one of the main drivers of protoplanetary disk dispersal. The fully or partially ionized disk surface is expect…
Multi-epoch VLBA HO maser observations toward the massive YSOs AFGL 2591 VLA 2 and VLA 3
J. M. Torrelles, M. A. Trinidad, S. Curiel +8
We present multi-epoch Very Long Baseline Array (VLBA) HO maser observations toward the massive young stellar objects (YSOs) VLA 2 and VLA 3 in the star-forming region AFGL 259…
The counterjet of HH 30: new light on its binary driving source
Robert Estalella, Rosario López, Guillem Anglada +3
We present new [SII] images of the HH 30 jet and counterjet observed in 2006, 2007, and 2010 that allowed us to measure with improved accuracy the positions and proper motions of t…
Integral Field Spectroscopy Of The Brightest Knots Of Hh 223 In L723
R. López, B. García-Lorenzo, R. Estalella +3
HH 223 is the optical counterpart of a larger scale H2 outflow, driven by the protostellar source VLA 2A, in L723. Its poorly collimated and rather chaotic morphology suggested the…
