Millimeter-wave polarization of protoplanetary disks due to dust scattering

A Kataoka, T Muto, M Momose… - The Astrophysical …, 2015 - iopscience.iop.org
We present a new method to constrain the grain size in protoplanetary disks with
polarization observations at millimeter wavelengths. If dust grains are grown to the size …

Global simulations of protoplanetary disks with net magnetic flux-i. non-ideal mhd case

W Béthune, G Lesur, J Ferreira - Astronomy & Astrophysics, 2017 - aanda.org
Context. The planet-forming region of protoplanetary disks is cold, dense, and therefore
weakly ionized. For this reason, magnetohydrodynamic (MHD) turbulence is thought to be …

The evidence of radio polarization induced by the radiative grain alignment and self-scattering of dust grains in a protoplanetary disk

A Kataoka, T Tsukagoshi, A Pohl, T Muto… - The Astrophysical …, 2017 - iopscience.iop.org
The mechanisms causing millimeter-wave polarization in protoplanetary disks are under
debate. To disentangle the polarization mechanisms, we observe the protoplanetary disk …

ALMA reveals transition of polarization pattern with wavelength in HL Tau's disk

IW Stephens, H Yang, ZY Li, LW Looney… - The Astrophysical …, 2017 - iopscience.iop.org
The mechanism for producing polarized emission from protostellar disks at (sub) millimeter
