Cornelis P. Dullemond, Tilman Birnstiel, Jane Huang +12
A large fraction of the protoplanetary disks observed with ALMA display multiple well-defined and nearly perfectly circular rings in the continuum, in many cases with substantial p…
Consistent dust and gas models for protoplanetary disks III. Models for selected objects from the FP7 DIANA project
P. Woitke, I. Kamp, S. Antonellini +17
The European FP7 project DIANA has performed a coherent analysis of a large set of observations from protoplanetary disks by means of thermo-chemical disk models. The collected dat…
Flybys in protoplanetary discs: I. Gas and dust dynamics

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…
Bright Opportunities for Atmospheric Characterization of Small Planets: Masses and Radii of K2-3 b, c, d and GJ3470 b from Radial Velocity Measurements and Spitzer Transits
Molly R. Kosiarek, Ian J. M. Crossfield, Kevin K. Hardegree-Ullman +36
We report improved masses, radii, and densities for four planets in two bright M-dwarf systems, K2-3 and GJ3470, derived from a combination of new radial velocity and transit obser…
A search for accreting young companions embedded in circumstellar disks: High-contrast H imaging with VLT/SPHERE
G. Cugno, S. P. Quanz, S. Hunziker +37
Aims: We want to detect and quantify observables related to accretion processes occurring locally in circumstellar disks, which could be attributed to young forming planets. We foc…
The Disk Substructures at High Angular Resolution Project (DSHARP): II. Characteristics of Annular Substructures
Jane Huang, Sean M. Andrews, Cornelis P. Dullemond +14
The Disk Substructures at High Angular Resolution Project used ALMA to map the 1.25 millimeter continuum of protoplanetary disks at a spatial resolution of ~5 au. We present a syst…
SOPHIE velocimetry of Kepler transit candidates. XIX. The transiting temperate giant planet KOI-3680b
G. Hebrard, A. S. Bonomo, R. F. Diaz +15
Whereas thousands of transiting giant exoplanets are known today, only a few are well characterized with long orbital periods. Here we present KOI-3680b, a new planet in this categ…
Analysis of Neptune's 2017 Bright Equatorial Storm
Edward Molter, Imke de Pater, Statia Luszcz-Cook +22
We report the discovery of a large (8500 km diameter) infrared-bright storm at Neptune's equator in June 2017. We tracked the storm over a period of 7 months with high-cadenc…
Stability of planets in triple star systems
F. Busetti, H. Beust, C. Harley
Context: Numerous theoretical studies of the stellar dynamics of triple systems have been carried out, but fewer purely empirical studies that have addressed planetary orbits withi…
Machine-learning Approaches to Exoplanet Transit Detection and Candidate Validation in Wide-field Ground-based Surveys
N. Schanche, A. Collier Cameron, G. Hébrard +23
Since the start of the Wide Angle Search for Planets (WASP) program, more than 160 transiting exoplanets have been discovered in the WASP data. In the past, possible transit-like e…
Variable Outer Disk Shadowing Around the Dipper Star RX J1604.3-2130
P. Pinilla, M. Benisty, J. de Boer +6
Low brightness dips have been recently observed in images of protoplanetary disks, and they are believed to be shadows by the inner disk. We present VLT/SPHERE polarimetric differe…
Super-Earths in the TW Hya disc
Daniel Mentiplay, Daniel J. Price, Christophe Pinte
We test the hypothesis that the sub-millimetre thermal emission and scattered light gaps seen in recent observations of TW Hya are caused by planet-disc interactions. We perform gl…
The Ring Structure in the MWC 480 Disk Revealed by ALMA
Yao Liu, Giovanni Dipierro, Enrico Ragusa +20
Gap-like structures in protoplanetary disks are likely related to planet formation processes. In this paper, we present and analyze high resolution (0.17*0.11 arcsec) 1.3 mm ALMA c…
Polarization of stars with debris disks: comparing observations with models
Julien Vandeportal, Pierre Bastien, Amélie Simon +2
The Space telescope carried out an unprecedented survey of nearby stars for debris disks. The dust present in these debris disks scatters and polarizes stellar light in…
