Monitoring of the polarized maser emission around the massive protostars W75N(B)-VLA1 and W75N(B)-VLA2
G. Surcis, W. H. T. Vlemmings, C. Goddi +8
Several radio sources have been detected in the HMSFR W75N(B), among them the massive YSOs VLA1 and VLA2 are of great interest. These are thought to be in different evolutionary st…
A Radio Pinwheel Emanating from WR147
Luis F. Rodríguez, Jane Arthur, Gabriela Montes +2
Wolf-Rayet (WR) stars are evolved massive stars, presumably on their way to becoming supernova. They are characterized by high luminosities and fast and dense stellar winds. We hav…
Characterizing the radio continuum nature of sources in the massive star-forming region W75N (B)
A. Rodríguez-Kamenetzky, C. Carrasco-González, J. M. Torrelles +11
The massive star-forming region W75N~(B) is thought to host a cluster of massive protostars (VLA~1, VLA~2, and VLA~3) undergoing different evolutionary stages. In this work, we pre…
Exploring the Grain Properties in the Disk of HL Tau with an Evolutionary Model
Carlos Tapia, Susana Lizano, Anibal Sierra +2
We model the ALMA and VLA millimeter radial profiles of the disk around HL Tau to constrain the properties of the dust grains. We adopt the disk evolutionary models of Lynden-Bell…
Polarization in Disks
Ian Stephens, Zhi-Yun Li, Haifeng Yang +24
Polarized dust emission outside of disks reveal the magnetic field morphology of molecular clouds. Within disks, however, polarized dust emission can arise from very different mech…
Unveiling a cluster of protostellar disks around the massive protostar GGD27 MM1
G. Busquet, J. M. Girart, R. Estalella +9
We used ALMA to observe the star-forming region GGD27 at 1.14 mm with an unprecedented angular resolution, 40 mas (56 au) and sensitivity (0.002 Msun). We detected a cluster of 25…
A 1.3 mm SMA Survey of 29 Variable Young Stellar Objects
Hauyu Baobab Liu, Michael M. Dunham, Ilaria Pascucci +16
Young stellar objects (YSOs) may undergo periods of active accretion (outbursts), during which the protostellar accretion rate is temporarily enhanced by a few orders of magnitude.…
Detection of Linearly Polarized 6.9 mm Continuum Emission from the Class 0 Young Stellar Object NGC1333 IRAS4A
Hauyu Baobab Liu, Shih-Ping Lai, Yasuhiro Hasegawa +7
We report new Karl G. Jansky Very Large Array (JVLA), 0.5 angular resolution observations of linearly polarized continuum emission at 6.9 mm, towards the Class 0 young stellar o…
Absence of Significant Cool Disks in Young Stellar Objects Exhibiting Repetitive Optical Outbursts
Hauyu Baobab Liu, Roberto Galván-Madrid, Eduard I. Vorobyov +10
We report Submillimeter Array (SMA) 1.3 mm high angular resolution observations towards the four EXor type outbursting young stellar objects (YSOs) VY Tau, V1118 Ori, V1143 Ori, an…
Investigating Particle Acceleration in Protostellar Jets: The Triple Radio Continuum Source in Serpens
Adriana Rodríguez-Kamenetzky, Carlos Carrasco-González, Anabella Araudo +5
While most protostellar jets present free-free emission at radio wavelengths, synchrotron emission has been also proposed to be present in a handful of these objects. The presence…
Proper motions of the outer knots of the HH 80/81/80N radio-jet
Josep M. Masqué, Luis F. Rodríguez, Anabella Araudo +5
(abridged) The HH 80/81/80N jet extends from the HH 80 object to the recently discovered Source 34 and has a total projected jet size of 10.3 pc, constituting the largest collimate…
A Study of Radio Polarization in Protostellar Jets
Mariana Cécere, Pablo F. Velázquez, Anabella T. Araudo +4
Synchrotron radiation is commonly observed in connection with shocks of different velocities, ranging from relativistic shocks associated with active galactic nuclei, gamma-ray bur…
Weak and Compact Radio Emission in Early Massive Star Formation Regions: An Ionized Jet Toward G11.11-0.12P1
V. Rosero, P. Hofner, M. McCoy +9
We report 1.3 cm and 6 cm continuum observations toward the massive proto-stellar candidate G11.11-0.12P1 using the Karl G. Jansky Very Large Array (VLA). We detect a string of fou…
A very young, compact bipolar HO maser outflow in the intermediate-mass star-forming LkH 234 region
J. M. Torrelles, S. Curiel, R. Estalella +8
We report multi-epoch VLBI HO maser observations towards the compact cluster of YSOs close to the Herbig Be star LkH 234. This cluster includes LkH 234 and at least nine…
Formation and evolution of the water maser outflow event in AFGL 2591 VLA 3-N
M. A. Trinidad, S. Curiel, R. Estalella +8
In this paper we analyze multi-epoch Very Long Baseline Interferometry (VLBI) water maser observations carried out with the Very Long Baseline Array (VLBA) toward the high-mass sta…
