Panchromatic (Sub)millimeter Polarization Observations of HL Tau Unveil Aligned Scattering Grains
Zhe-Yu Daniel Lin, Zhi-Yun Li, Ian W. Stephens +14
Polarization is a unique tool to study the properties of dust grains of protoplanetary disks and detail the initial conditions of planet formation. Polarization around HL Tau was p…
Finding substructures in protostellar disks in Ophiuchus
Arnaud Michel, Sarah I. Sadavoy, Patrick D. Sheehan +5
High-resolution, millimeter observations of disks at the protoplanetary stage reveal substructures such as gaps, rings, arcs, spirals, and cavities. While many protoplanetary disks…
A millimeter-multiwavelength continuum study of VLA 1623 West
Arnaud Michel, Sarah I. Sadavoy, Patrick D. Sheehan +2
VLA 1623 West is an ambiguous source that has been described as a shocked cloudlet as well as a protostellar disk. We use deep ALMA 1.3 and 0.87 millimeter observations to constrai…
