Material Transport in Protoplanetary Discs with Massive Embedded Planets
Hannah J. Petrovic, Richard A. Booth, Cathie J. Clarke
Vertical gas and dust flows in protoplanetary discs waft material above the midplane region in the presence of a protoplanet. This motion may alter the delivery of dust to the plan…
Photoevaporation of protoplanetary discs with PLUTO+PRIZMO I. Lower X-ray-driven mass-loss rates due to enhanced cooling
Andrew D. Sellek, Tommaso Grassi, Giovanni Picogna +3
Context: Photoevaporation is an important process for protoplanetary disc dispersal but there has so far been a lack of consensus from simulations over the mass-loss rates and the…
Inner walls or vortices? Crescent-shaped asymmetries in ALMA observations of protoplanetary discs
Álvaro Ribas, Cathie J. Clarke, Francesco Zagaria
Crescent-shaped asymmetries are common in millimetre observations of protoplanetary discs and are usually attributed to vortices or dust overdensities. However, they often appear o…
Seeing the unseen: a method to detect unresolved rings in protoplanetary disks
Chiara E. Scardoni, Richard A. Booth, Cathie J. Clarke +2
While high resolution ALMA observations reveal a wealth of substructure in protoplanetary discs, they remain incapable of resolving the types of small scale dust structures predict…
Angular momentum transport via gravitational instability in the Elias 2-27 disc
Cristiano Longarini, Giuseppe Lodato, Cathie J. Clarke +6
Gravitational instability is thought to be one of the main drivers of angular momentum transport in young protoplanetary discs. The disc around Elias 2-27 offers a unique example o…
Searching for planet-driven dust spirals in ALMA visibilities
Edward T. Stevenson, Álvaro Ribas, Jessica Speedie +2
ALMA (Atacama Large Millimetre/submillimetre Array) observations of the thermal emission from protoplanetary disc dust have revealed a wealth of substructures that could evidence e…
