Constraining the Stellar Masses and Origin of the Protostellar VLA 1623 System
Sarah I Sadavoy, Patrick Sheehan, John J. Tobin +6
We present ALMA Band 7 molecular line observations of the protostars within the VLA 1623 system. We map CO (3 - 2) in the circumbinary disk around VLA 1623A and the outflow…
Eccentric Dust Ring in the IRS 48 Transition Disk
Haifeng Yang, Manuel Fernandez-Lopez, Zhi-Yun Li +4
Crescent-shaped structures in transition disks hold the key to studying the putative companions to the central stars. The dust dynamics, especially that of different grain sizes, i…
The Evolution of Protostellar Outflow Cavities, Kinematics, and Angular Distribution of Momentum and Energy in Orion A: Evidence for Dynamical Cores
Cheng-Han Hsieh, Héctor G. Arce, Zhi-Yun Li +13
We present Atacama Large Millimeter/submillimeter Array observations of the 10 kAU environment surrounding 21 protostars in the Orion A molecular cloud tracing outflows. Our…
Thermal Emission and Scattering by Aligned Grains: Plane-Parallel Model and Application to Multiwavelength Polarization of the HL Tau Disk
Zhe-Yu Daniel Lin, Zhi-Yun Li, Haifeng Yang +4
Telescopes are now able to resolve dust polarization across circumstellar disks at multiple wavelengths, allowing the study of the polarization spectrum. Most disks show clear evid…
HAWC+/SOFIA Polarimetry in L1688: Relative Orientation of Magnetic Field and Elongated Cloud Structure
Dennis Lee, Marc Berthoud, Che-Yu Chen +14
We present a study of the relative orientation between the magnetic field and elongated cloud structures for the Oph A and Oph E regions in L1688 in the Ophiuchus molecular…
Low Level Carbon Monoxide Line Polarization in two Protoplanetary Disks: HD 142527 and IM Lup
Ian W. Stephens, Manuel Fernandez-Lopez, Zhi-Yun Li +2
Magnetic fields are expected to play an important role in accretion processes for circumstellar disks. Measuring the magnetic field morphology is difficult, especially since polari…
