Environmental interactions in Class II systems and their impact on the disk-planet architecture

Pedro P. Poblete, Nicolás Cuello, Tim D. Pearce +4

Protoplanetary disks evolve in clustered environments where interactions with nearby stars and interstellar gas are common. Such environmental processes, including stellar flybys a…

Asymmetric radiation in binary systems: Implications for disk evolution and chemistry

Pedro P. Poblete, Nicolás Cuello, Antoine Alaguero +4

Current models of binary systems often depend on simplified approach of the radiation field, which are unlikely to accurately capture the complexities of asymmetric environments. W…

The HR 8799 Debris Disc: Shaped by Planetary Migration and a Possible Fifth Outermost Planet

Pedro P. Poblete, Tim D. Pearce, Carolina Charalambous

Context. The HR 8799 system, hosting four giant planets between a warm and cold debris disc, and an extended dusty tail beyond, serves as an ideal laboratory for studying planetary…

Circumstellar and circumbinary discs in multiple stellar systems

Nicolás Cuello, Antoine Alaguero, Pedro P. Poblete

The interplay between stellar multiplicity and protoplanetary discs represents a cornerstone of modern astrophysics, offering key insights into the processes of planet formation. P…

Self-gravity of debris discs can strongly change the outcomes of interactions with inclined planets

Pedro P. Poblete, Torsten Löhne, Tim D. Pearce +1

Drastic changes in protoplanets' orbits could occur in the early stages of planetary systems through interactions with other planets and their surrounding protoplanetary or debris…

A kinematic excess in the annular gap and gas depleted cavity in the disc around HD 169142

Himanshi Garg, Christophe Pinte, Iain Hammond +6

We present ALMA band 6 images of the 12CO, 13CO and C18O J=2-1 line emissions for the circumstellar disc around HD 169142, at ~8 au spatial resolution. We resolve a central gas dep…

The protoplanetary disc around HD 169142: circumstellar or circumbinary?

P. P. Poblete, N. Cuello, S. Pérez +12

Stellar binaries represent a substantial fraction of stellar systems, especially among young stellar objects. Accordingly, binaries play an important role in setting the architectu…

Long live the disk: lifetimes of protoplanetary disks in hierarchical triple star systems and a possible explanation for HD 98800 B

María Paula Ronco, Octavio M. Guilera, Jorge Cuadra +5

The gas dissipation from a protoplanetary disk is one of the key processes affecting planet formation, and it is widely accepted that it happens on timescales of a few million year…

Fomalhaut b could be massive and sculpting the narrow, eccentric debris disc, if in mean-motion resonance with it

Tim D. Pearce, Hervé Beust, Virginie Faramaz +4

The star Fomalhaut hosts a narrow, eccentric debris disc, plus a highly eccentric companion Fomalhaut b. It is often argued that Fomalhaut b cannot have significant mass, otherwise…

Binary-induced spiral arms inside the disc cavity of AB Aurigae

Pedro P. Poblete, Josh Calcino, Nicolás Cuello +5

In this work we demonstrate that the inner spiral structure observed in AB Aurigae can be created by a binary star orbiting inside the dust cavity. We find that a companion with a…

Dusty clumps in circumbinary discs

Pedro P. Poblete, Nicolás Cuello, Jorge Cuadra

Recent observations have revealed that protoplanetary discs often exhibit cavities and azimuthal asymmetries such as dust traps and clumps. The presence of a stellar binary system…

Flybys in protoplanetary discs: I. Gas and dust dynamics

Nicolás Cuello, Giovanni Dipierro, Daniel Mentiplay +7

We present 3D smoothed particle hydrodynamics simulations of protoplanetary discs undergoing a flyby by a stellar perturber on a parabolic orbit lying in a plane inclined relative…

F.S.I.: Flyby Scene Investigation

Nicolás Cuello, Giovanni Dipierro, Daniel Mentiplay +7

We present a methodology to interpret observations of protoplanetary discs where a flyby, also called a tidal encounter, is suspected. In case of a flyby, protoplanetary discs can…
