Dust Settling Instability in Protoplanetary Discs
Leonardo Krapp, Andrew N. Youdin, Kaitlin M. Kratter +1
The streaming instability (SI) has been extensively studied in the linear and non-linear regimes as a mechanism to concentrate solids and trigger planetesimal formation in the midp…
Predicting the observational signature of migrating Neptune-sized planets in low-viscosity disks
Philipp Weber, Sebastián Pérez, Pablo Benítez-Llambay +3
The migration of planetary cores embedded in a protoplanetary disk is an important mechanism within planet-formation theory, relevant for the architecture of planetary systems. Con…
Streaming Instability for Particle-Size Distributions
Leonardo Krapp, Pablo Benítez-Llambay, Oliver Gressel +1
The streaming instability is thought to play a central role in the early stages of planet formation by enabling the efficient bypass of a number of barriers hindering the formation…
Long Baseline Observations of the HD100546 Protoplanetary Disk with ALMA
Sebastián Pérez, Simon Casassus, Antonio Hales +9
Using the Atacama Large Millimeter/submillimeter Array (ALMA), we observed the young Herbig star HD 100546, host to a prominent disk with a deep, wide gap in the dust. The high-res…
Probing the Protosolar Disk Using Dust Filtering at Gaps in the Early Solar System
Troels Haugbølle, Philipp Weber, Daniel P. Wielandt +4
Jupiter and Saturn formed early, before the gas disk dispersed. The presence of gap-opening planets affects the dynamics of the gas and embedded solids and halts the inward drift o…
Migrating super-Earths in low-viscosity discs: unveiling the roles of feedback, vortices, and laminar accretion flows
Colin P. McNally, Richard P. Nelson, Sijme-Jan Paardekooper +1
We present the highest resolution study to date of super-Earths migrating in inviscid and low-viscosity discs, motivated by the connection to laminar, wind-driven models of protopl…
Asymptotically stable numerical method for multispecies momentum transfer: gas and multifluid-dust test suite and implementation in FARGO3D
Pablo Benítez-Llambay, Leonardo Krapp, Martín E. Pessah
We present an asymptotically and unconditionally stable numerical method to account for the momentum transfer between multiple species. Momentum is conserved to machine precision.…
Dust segregation in Hall-dominated turbulent protoplanetary disks
Leonardo Krapp, Oliver Gressel, Pablo Benítez-Llambay +3
Imaging of the dust continuum emitted from disks around nearby protostars reveals diverse substructure. In recent years, theoretical efforts have been intensified to investigate ho…
Observability of planet-disc interactions in CO kinematics
Sebastian Perez, Simon Casassus, Pablo Benítez-Llambay
Empirical evidence of planets in gas-rich circumstellar discs is required to constrain giant planet formation theories. Here we study the kinematic patterns which arise from planet…
Orbital migration and Resonance Offset of the Kepler-25 and K2-24 systems
C. Charalambous, X. S. Ramos, P. Benítez-Llambay +1
Based on the model described in Ramos et al., 2017, we present an analytical+numerical study of the resonance capture under Type-I migration for the Kepler-25 (Marcy et al., 2014)…
Characterizing the variable dust permeability of planet-induced gaps
Philipp Weber, Pablo Benítez-Llambay, Oliver Gressel +2
Aerodynamic theory predicts that dust grains in protoplanetary disks will drift radially inward on comparatively short timescales. In this context, it has long been known that the…
Torques Induced by Scattered Pebble-flow in Protoplanetary Disks
Pablo Benítez-Llambay, Martin E. Pessah
Fast inward migration of planetary cores is a common problem in the current planet formation paradigm. Even though dust is ubiquitous in protoplanetary disks, its dynamical role in…
Long-term and large-scale hydrodynamical simulations of migrating planets
Pablo Benítez-Llambay, Ximena S. Ramos, Cristian Beaugé +1
We present a new method that allows long-term and large-scale hydrodynamical simulations of migrating planets over a grid-based Eulerian code. This technique, which consists in a r…
FARGO3D: A new GPU-oriented MHD code
Pablo Benítez-Llambay, Frédéric Masset
We present the FARGO3D code, recently publicly released. It is a magnetohydrodynamics code developed with special emphasis on protoplanetary disks physics and planet-disk interacti…
