Rotation and winds of exoplanet HD 189733 b measured with high-dispersion transmission spectroscopy
M. Brogi, R. J. de Kok, S. Albrecht +3
Giant exoplanets orbiting very close to their parent star (hot Jupiters) are subject to tidal forces expected to synchronize their rotational and orbital periods on short timescale…
Molecular Oxygen in Oort Cloud Comet 1P/Halley
Martin Rubin, Kathrin Altwegg, Ewine F. van Dishoeck +1
Recently the ROSINA mass spectrometer suite on board the European Space Agency's Rosetta spacecraft discovered an abundant amount of molecular oxygen, O2, in the coma of Jupiter fa…
Resolved gas cavities in transitional disks inferred from CO isotopologues with ALMA
Nienke van der Marel, Ewine F. van Dishoeck, Simon Bruderer +5
Transitional disks around young stars are promising candidates to look for recently formed, embedded planets. Planet-disk interaction models predict that planets clear a gap in the…
ALMA Observations of a Gap and a Ring in the Protoplanetary Disk around TW Hya
Hideko Nomura, Takashi Tsukagoshi, Ryohei Kawabe +8
We report the first detection of a gap and a ring in 336 GHz dust continuum emission from the protoplanetary disk around TW Hya, using the Atacama Large Millimeter/Submillimeter Ar…
Imaging Jupiter's radiation belts down to 127 MHz with LOFAR
J. N. Girard, P. Zarka, C. Tasse +71
Context. Observing Jupiter's synchrotron emission from the Earth remains today the sole method to scrutinize the distribution and dynamical behavior of the ultra energetic electron…
A tunnel and a traffic jam: How transition disks maintain a detectable warm dust component despite the presence of a large planet-carved gap
Paola Pinilla, Lucia Klarmann, Tilman Birnstiel +3
We combined hydrodynamical simulations of planet-disk interactions with dust evolution models that include coagulation and fragmentation of dust grains over a large range of radii…
Direct imaging of the water snow line at the time of planet formation using two ALMA continuum bands
Andrea Banzatti, Paola Pinilla, Luca Ricci +3
Molecular snow lines in protoplanetary disks have been studied theoretically for decades because of their importance in shaping planetary architectures and compositions. The water…
First light of the VLT planet finder SPHERE. II. The physical properties and the architecture of the young systems PZ Tel and HD 1160 revisited
A. -L. Maire, M. Bonnefoy, C. Ginski +68
[Abridged] Context. The young systems PZ Tel and HD 1160, hosting known low-mass companions, were observed during the commissioning of the new planet finder SPHERE with several ima…
First light of the VLT planet finder SPHERE. I. Detection and characterization of the sub-stellar companion GJ 758 B
A. Vigan, M. Bonnefoy, C. Ginski +72
GJ758 B is a brown dwarf companion to a nearby (15.76 pc) solar-type, metal-rich (M/H = +0.2 dex) main-sequence star (G9V) that was discovered with Subaru/HiCIAO in 2009. From prev…
Consistent dust and gas models for protoplanetary disks. I. Disk shape, dust settling, opacities, and PAHs
P. Woitke, M. Min, C. Pinte +19
We propose a set of standard assumptions for the modelling of Class II and III protoplanetary disks, which includes detailed continuum radiative transfer, thermo-chemical modelling…
Variability and dust filtration in the transition disk J160421.7-213028 observed in optical scattered light
P. Pinilla, J. de Boer, M. Benisty +9
Context. Some of transition disks show asymmetric structures in thermal sub-millimetre emission and optical scattered light. These structures can be the result of planet(s) or comp…
Testing particle trapping in transition disks with ALMA
P. Pinilla, N. van der Marel, L. M. Pérez +6
We present new Atacama Large Millimeter/submillimeter Array (ALMA) continuum observations at 336GHz of two transition disks, SR21 and HD135344B. In combination with previous ALMA o…
K2-31b, a grazing transiting hot Jupiter on an 1.26-day orbit around a bright G7V star
S. Grziwa, D. Gandolfi, Sz. Csizmadia +25
We report the discovery of K2-31b, the first confirmed transiting hot Jupiter detected by the K2 space mission. We combined K2 photometry with FastCam lucky imaging and FIES and HA…
Vortex Formation and Evolution in Planet Harboring Disks under Thermal Relaxation
A. Lobo Gomes, H. Klahr, A. L. Uribe +2
We study the evolution of planet-induced vortices in radially stratified disks, with initial conditions allowing for radial buoyancy. For this purpose we run global two dimensional…
Transiting exoplanets from the CoRoT space mission XXVIII. CoRoT-33b, an object in the brown dwarf desert with 2:3 commensurability with its host star
Sz. Csizmadia, A. Hatzes, D. Gandolfi +32
We report the detection of a rare transiting brown dwarf with a mass of 59 M_Jup and radius of 1.1 R_Jup around the metal-rich, [Fe/H] = +0.44, G9V star CoRoT-33. The orbit is ecce…
Scattered light images of spiral arms in marginally gravitationally unstable discs with an embedded planet
A. Pohl, P. Pinilla, M. Benisty +5
Scattered light images of transition discs in the near-infrared often show non-axisymmetric structures in the form of wide-open spiral arms in addition to their characteristic low-…
Using the chromatic Rossiter-McLaughlin effect to probe the broadband signature in the optical transmission spectrum of HD 189733b
E. Di Gloria, I. A. G. Snellen, S. Albrecht
Transmission spectroscopy is a powerful technique for probing exoplanetary atmospheres. A successful ground-based observational method uses a differential technique based on high-d…
The molecular composition of the planet-forming regions of protoplanetary disks across the luminosity regime
Catherine Walsh, Hideko Nomura, Ewine F. van Dishoeck
(Abridged) Near- to mid-IR observations of protoplanetary disks show that the inner regions (<10AU) are rich in small organic volatiles (e.g., C2H2 and HCN). Trends in the data sug…

Lucie Jilkova, Simon Portegies Zwart, Tjibaria Pijloo +1
The discovery of 2012VP113 initiated the debate on the origin of the Sedna family of planetesimals in orbit around the Sun. Sednitos roam the outer regions of the Solar System betw…
A triple origin for the lack of tight coplanar circumbinary planets around short-period binaries
Adrian S. Hamers, Hagai B. Perets, Simon F. Portegies Zwart
Transiting circumbinary planets are more easily detected around short-period than long-period binaries, but none have yet been observed by {\it Kepler} orbiting binaries with perio…
