Gap, shadows, spirals, streamers: SPHERE observations of binary-disk interactions in GG Tau A
M. Keppler, A. Penzlin, M. Benisty +31
A large fraction of stars is found to be part of binary or higher-order multiple systems. The ubiquity of planets found around single stars raises the question if and how planets i…
Self-scattering of non-spherical dust grains
Florian Kirchschlager, Gesa H. -M. Bertrang
The understanding of (sub-)millimetre polarisation has made a leap forward since high-resolution imaging with ALMA came available. Amongst other effects, self-scattering (i.e., sca…
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…
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…
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…
Magnetic fields in Bok globules: Multi-wavelength polarimetry as tracer across large spatial scales
Sebastian Jorquera, Gesa H. -M. Bertrang
[abridged] The role of magnetic fields in the process of star formation is a matter of continuous debate. Clear observational proof of the general influence of magnetic fields on t…
