Disks Around T Tauri Stars with SPHERE (DARTTS-S) II: Twenty-one new polarimetric images of young stellar disks
Antonio Garufi, Henning Avenhaus, Sebastian Perez +8
Near-IR polarimetric images of protoplanetary disks enable us to characterize substructures that might be due to the interaction with (forming) planets. The available census is str…
Characterization of Ring Substructures in the Protoplanetary Disk of HD 169142 from Multi-Wavelength ALMA Observations
Enrique Macias, Catherine Espaillat, Mayra Osorio +10
We present a detailed multi-wavelength characterization of the multi-ring disk of HD 169142. We report new ALMA observations at 3 mm and analyze them together with archival 0.89 an…
Intrinsic polarisation of elongated porous dust grains
Florian Kirchschlager, Gesa H. -M. Bertrang, Mario Flock
ALMA observations revealed recently polarised radiation of several protoplanetary disks in the (sub-)millimetre wavelength range. Besides self-scattering of large particles, therma…
Polarization in Disks
Ian Stephens, Zhi-Yun Li, Haifeng Yang +24
Polarized dust emission outside of disks reveal the magnetic field morphology of molecular clouds. Within disks, however, polarized dust emission can arise from very different mech…
Highly structured disk around the planet host PDS 70 revealed by high-angular resolution observations with ALMA
M. Keppler, R. Teague, J. Bae +19
PDS 70b is the most robustly detected young planet imaged in the gap of a transition disk so far, found at a separation of ~195 mas (~22 au) from its host star and at a position an…
Resolved imaging of the AR Puppis circumbinary disk
S. Ertel, D. Kamath, M. Hillen +14
Circumbinary disks are common around post-asymptotic giant branch (post-AGB) stars with a stellar companion on orbital time scales of a few 100 to few 1000 days. The presence of a…
