Outflows, envelopes, and disks as evolutionary indicators in Lupus YSOs
M. M. Vazzano, M. Fernández-López, A. Plunkett +4
By studying 7 objects in the Lupus clouds we aim to test if a coherence exists between commonly used evolutionary tracers. We present ALMA observations of the continuum and molecul…
Confirming the Explosive Outflow in G5.89 with ALMA
Luis A. Zapata, Paul T. P. Ho, Manuel Fernández-López +9
The explosive molecular outflow detected decades ago in the Orion BN/KL region of massive star formation was considered to be a bizarre event. This belief was strengthened by the n…
Four annular structures in a protostellar disk less than 500,000 years old
Dominique M. Segura-Cox, Anika Schmiedeke, Jaime E. Pineda +8
Annular structures, or rings and gaps, in disks around pre-main sequence stars have been detected in abundance towards Class II objects ~1,000,000 years in age. These structures ar…
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…
ALMA Observations of Polarized 872 m Dust Emission from the Protostellar Systems VLA 1623 and L1527
Robert J. Harris, Erin G. Cox, Leslie W. Looney +8
We present high-sensitivity ( mJy, mJy), high-resolution (0.12-0.2 arcsec) observations of polarized 872 m dust emission from the young multiple…
Distribution of Serpens South protostars revealed with ALMA
Adele L. Plunkett, Manuel Fernández-López, Héctor G. Arce +3
Aims: We investigated the masses and spatial distributions of pre-stellar and protostellar candidates in the young, low-mass star forming region Serpens South, where active star fo…
ALMA Reveals A Collision Between Protostellar Outflows in BHR71
Luis A. Zapata, Manuel Fernández-López, Luis F. Rodríguez +4
For a binary protostellar outflow system in which its members are located so close to each other (the separation being smaller than the addition of the widths of the flows) and wit…
ALMA Reveals Transition of Polarization Pattern with Wavelength in HL Tau's Disk
Ian W. Stephens, Haifeng Yang, Zhi-Yun Li +10
The mechanism for producing polarized emission from protostellar disks at (sub)millimeter wavelengths is currently uncertain. Classically, polarization is expected from non-spheric…
The circumestellar disk of the B0 protostar powering the HH 80-81 radio jet
J. M. Girart, R. Estalella, M. Fernández-López +6
We present subarcsecond angular resolution observations carried out with the Submillimeter Array (SMA) at 880 m centered at the B0-type protostar GGD27~MM1, the driving source o…
1.3mm polarized emission in the circumstellar disk of a massive protostar
M. Fernández-López, I. W. Stephens, J. M. Girart +5
We present the first resolved observations of the 1.3mm polarized emission from the disk-like structure surrounding the high-mass protostar Cepheus A HW2. These CARMA data partiall…
Spatially Resolved Magnetic Field Structure in the Disk of a T Tauri Star
Ian W. Stephens, Leslie W. Looney, Woojin Kwon +6
Magnetic fields in accretion disks play a dominant role during the star formation process but have hitherto been observationally poorly constrained. Field strengths have been infer…
Shock Dynamics In Relativistic Jets
J. Cantó, S. Lizano, M. Fernández-López +2
We present a formalism of the dynamics of internal shocks in relativistic jets where the source has a time-dependent injection velocity and mass-loss rate. The variation of the inj…
A rotating molecular disk toward IRAS 18162-2048, the exciting source of HH 80-81
Manuel Fernández-López, Josep M. Girart, Salvador Curiel +3
We present several molecular line emission arcsec and subarcsec observations obtained with the Submillimeter Array (SMA) in the direction of the massive protostar IRAS 18162-2048,…
Millimeter and submillimeter high angular resolution interferometric observations: dust in the heart of IRAS 18162-2048
M. Fernández-López, S. Curiel, J. M. Girart +3
The GGD27 complex includes the HH 80-81-80N system, which is one of the most powerful molecular outflows associated with a high mass star-forming region observed up to now. This ou…
