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…
Badminton Birdie-Like Aerodynamic Alignment of Drifting Dust Grains by Subsonic Gaseous Flows in Protoplanetary Disks
Zhe-Yu Daniel Lin, Zhi-Yun Li, Haifeng Yang +4
Recent (sub)millimeter polarization observations of protoplanetary disks reveal toroidally aligned, effectively prolate dust grains large enough (at least ~100 m) to efficientl…
Magnetic Fields in the Pillars of Creation
Adwitiya Sarkar, Leslie W. Looney, Marc W. Pound +7
Due to dust grain alignment with magnetic fields, dust polarization observations of far-infrared emission from cold molecular clouds are often used to trace magnetic fields, allowi…
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…
