Imaging [CI] around HD 131835: reinterpreting young debris discs with protoplanetary disc levels of CO gas as shielded secondary discs
Quentin Kral, Sebastian Marino, Mark C. Wyatt +2
Despite being Myr, there are 10 debris discs with as much CO gas as in protoplanetary discs. Such discs have been assumed to be "hybrid", i.e., with secondary dust but p…
Scattering of exocomets by a planet chain: exozodi levels and the delivery of cometary material to inner planets
Sebastian Marino, Amy Bonsor, Mark C. Wyatt +1
Exocomets scattered by planets have been invoked to explain observations in multiple contexts, including the frequently found near- and mid-infrared excess around nearby stars aris…
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…
Cometary impactors on the TRAPPIST-1 planets can destroy all planetary atmospheres and rebuild secondary atmospheres on planets f, g, h
Quentin Kral, Mark C. Wyatt, Amaury H. M. J. Triaud +3
The TRAPPIST-1 system is unique in that it has a chain of seven terrestrial Earth-like planets located close to or in its habitable zone. In this paper, we study the effect of pote…
ALMA observations of the narrow HR 4796A debris ring
Grant M. Kennedy, Sebastian Marino, Luca Matra +4
The young A0V star HR 4796A is host to a bright and narrow ring of dust, thought to originate in collisions between planetesimals within a belt analogous to the Solar System's Edge…
