Multi-band ALMA Polarization Observations of BHB07-11 Reveal Aligned Dust Grains in Complex Spiral Arm Structures
Austen Fourkas, Leslie W. Looney, Zhe-Yu Daniel Lin +8
Polarization-mode observations from the Atacama Large Millimeter/submillimeter Array (ALMA) are powerful tools for studying the dust grain populations in circumstellar disks. Many…
L1448 IRS3B: Dust Polarization Aligned with Spiral Features, Tracing Gas Flows
Leslie W. Looney, Zhe-Yu Daniel Lin, Zhi-Yun Li +11
Circumstellar disk dust polarization in the (sub)millimeter is, for the most part, not from dust grain alignment with magnetic fields but rather indicative of a combination of dust…
Magnetic Fields Observed along the E-W Outflow of IRAS 16293-2422
Frankie J. Encalada, Leslie W. Looney, Giles Novak +6
Magnetic fields likely play an important role in the formation of young protostars. Multiscale and multiwavelength dust polarization observations can reveal the inferred magnetic f…
Protoplanetary Disk Polarization at Multiple Wavelengths: Are Dust Populations Diverse?
Rachel E. Harrison, Zhe-Yu Daniel Lin, Leslie W. Looney +4
Millimeter and sub-millimeter observations of continuum linear dust polarization provide insight into dust grain growth in protoplanetary disks, which are the progenitors of planet…
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 Twisted Magnetic Field of the Protobinary L483
Erin G. Cox, Giles Novak, Sarah Sadavoy +16
We present H-band (1.65 m) and SOFIA HAWC+ 154 m polarization observations of the low-mass core L483. Our H-band observations reveal a magnetic field that is overwhelmingly i…
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…
ALMA CN Zeeman Observations of AS 209: Limits on Magnetic Field Strength and Magnetically Driven Accretion Rate
Rachel E. Harrison, Leslie W. Looney, Ian W. Stephens +7
While magnetic fields likely play an important role in driving the evolution of protoplanetary disks through angular momentum transport, observational evidence of magnetic fields h…
Dust Polarization in Four Protoplanetary Disks at 3 mm: Further Evidence of Multiple Origins
Rachel E. Harrison, Leslie W. Looney, Ian W. Stephens +7
We present polarimetric observations of four Class II protoplanetary disks (DG Tau, Haro 6-13, RY Tau, and MWC 480) taken with the Atacama Large Millimeter/submillimeter Array (ALM…
