Spirals and clumps in V960 Mon: signs of planet formation via gravitational instability around an FU Ori star?
P. Weber, S. Pérez, A. Zurlo +11
The formation of giant planets has traditionally been divided into two pathways: core accretion and gravitational instability. However, in recent years, gravitational instability h…
The ALMA view of MP Mus (PDS 66): a protoplanetary disk with no visible gaps down to 4 au scales
Á. Ribas, E. Macías, P. Weber +12
We present ALMA multiwavelength observations of the protoplanetary disk around the nearby (d100 pc) young solar analog MP Mus (PDS 66). These observations at 0.89 mm, 1.3 mm,…
The Doppler-flip in HD100546 as a disk eruption: the elephant in the room of kinematic protoplanet searches
Simon Casassus, Miguel Carcamo, Antonio Hales +2
The interpretation of molecular-line data in terms of hydro dynamical simulations of planet-disk interactions fosters new hopes for the indirect detection of protoplanets. In a mod…
High-resolution ALMA observations of V4046Sgr: a circumbinary disc with a thin ring
Rafael Martinez-Brunner, Simon Casassus, Sebastián Pérez +8
The nearby V4046 Sgr spectroscopic binary hosts a gas-rich disc known for its wide cavity and dusty ring. We present high resolution (20 mas or 1.4 au) ALMA observations of t…
The steady-state hydrodynamics of a long-lived disc: planetary system architecture and prospects of observing a circumplanetary disc shadow in V4046Sgr
Philipp Weber, Simon Casassus, Sebastián Pérez
Recent imaging of the disc around the V4046Sgr spectroscopic binary revealed concentric regions of dust rings and gaps. The object's proximity and expected equilibrated state d…
A multiwavelength analysis of the spiral arms in the protoplanetary disk around WaOph 6
S. B. Brown-Sevilla, M. Keppler, M. Barraza-Alfaro +23
[Full abstract in the paper] In recent years, protoplanetary disks with spiral structures have been detected in scattered light, millimeter continuum, and CO gas emission. The mech…
A dusty filament and turbulent CO spirals in HD135344B-SAO206462
Simon Casassus, Valentin Christiaens, Miguel Carcamo +16
Planet-disc interactions build up local pressure maxima that may halt the radial drift of protoplanetary dust, and pile it up in rings and crescents. ALMA observations of the HD135…
Modeling the nonaxisymmetric structure in the HD 163296 disk with planet-disk interaction
Peter J. Rodenkirch, Thomas Rometsch, Cornelis P. Dullemond +2
High resolution ALMA observations revealed a variety of rich substructures in numerous protoplanetary disks. These structures consist of rings, gaps and asymmetric features. It is…
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…
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…
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…
