Circumbinary, not transitional: on the spiral arms, cavity, shadows, fast radial flows, streamers, and horseshoe in the HD 142527 disc
We present 3D hydrodynamical models of the HD 142527 protoplanetary disc, a bright and
well-studied disc that shows spirals and shadows in scattered light around a 100 au gas …

Polycyclic aromatic hydrocarbons in protoplanetary disks around Herbig Ae/Be and T Tauri stars
JY Seok, A Li - The Astrophysical Journal, 2017 - iopscience.iop.org
A distinct set of broad emission features at 3.3, 6.2, 7.7, 8.6, 11.3, and 12.7 μm, is often
detected in protoplanetary disks (PPDs). These features are commonly attributed to …
