ALMA Observations of the HD~110058 debris disk
Antonio S. Hales, SebastiÁn Marino, Patrick D. Sheehan +7
We present Atacama Large Millimeter Array (ALMA) observations of the young, gas-rich debris disk around HD110058 at 0.3-0.6\arcsec resolution. The disk is detected in the 0.85 and…
Cm-wavelength observations of MWC758: resolved dust trapping in a vortex
Simon Casassus, Sebastian Marino, Wladimir Lyra +13
The large crescents imaged by ALMA in transition disks suggest that azimuthal dust trapping concentrates the larger grains, but centimetre-wavelengths continuum observations are re…
An inner warp in the DoAr 44 T Tauri transition disk
Simon Casassus, Henning Avenhaus, Sebastian Perez +11
Optical/IR images of transition disks (TDs) have revealed deep intensity decrements in the rings of HAeBes HD142527 and HD100453, that can be interpreted as shadowing from sharply…
Circumbinary, not transitional: On the spiral arms, cavity, shadows, fast radial flows, streamers and horseshoe in the HD142527 disc
Daniel J. Price, Nicolas Cuello, Christophe Pinte +13
We present 3D hydrodynamical models of the HD142527 protoplanetary disc, a bright and well studied disc that shows spirals and shadows in scattered light around a 100 au gas cavity…
The ALMA early science view of FUor/EXor objects - V: continuum disc masses and sizes
Lucas A. Cieza, Dary Ruiz-Rodriguez, Sebastian Perez +9
Low-mass stars build a significant fraction of their total mass during short outbursts of enhanced accretion known as FUor and EXor outbursts. FUor objects are characterized by a s…
A compact concentration of large grains in the HD142527 protoplanetary dust trap
Simon Casassus, Chris Wright, Sebastian Marino +11
A pathway to the formation of planetesimals, and eventually giant planets, may occur in concentrations of dust grains trapped in pressure maxima. Dramatic crescent-shaped dust conc…
