Experimental evidence for granular shear-flow instability in the Epstein regime
Holly L. Capelo, Jean-David Bodénan, Martin Jutzi +7
Stability analysis of two-fluid protoplanetary disc models has enriched our understanding of how solids can grow into larger bodies called planetesimals. Dust particles entrained i…
An Adolescent and Near-Resonant Planetary System Near the End of Photoevaporation
Mu-Tian Wang, Fei Dai, Hui-Gen Liu +28
Young exoplanets provide vital insights into the early dynamical and atmospheric evolution of planetary systems. Many multi-planet systems younger than 100 Myr exhibit mean-motion…
The ESPRESSO Redshift Drift Experiment III -- The Third Epoch of QSO J052915.80-435152.0
Andrea Trost, Catarina M. J. Marques, S. Cristiani +25
The Sandage-Loeb test probes cosmic expansion directly by measuring the redshift drift in quasar absorption features in a model-independent way. In this series of papers, we have l…
Gas-depleted planet formation occurred in the four-planet system around the red dwarf LHS 1903
Thomas G. Wilson, Anna M. Simpson, Andrew Collier Cameron +173
Small exoplanet radii show two populations, referred to as super-Earths and sub-Neptunes, separated by a gap known as the radius valley. This may be produced by the removal of atmo…
Origin of Ganymede and the Galilean Moons
Yuhito Shibaike, Yann Alibert
Ganymede and the Galilean moons formed in a small gas disc around the gas-accreting proto-Jupiter, known as the circum-Jovian disc (CJD). The formation process of the satellites oc…
From Streaming Instability to the Onset of Pebble Accretion I. Investigating the Growth Modes in Planetesimal Rings
Nicolas Kaufmann, Octavio M. Guilera, Yann Alibert +1
Context. The localized formation of planetesimals can be triggered with the help of streaming instability when the local pebble density is high. This can happen at various location…
The New Generation Planetary Population Synthesis (NGPPS). V. Predetermination of planet types in global core accretion models
M. Schlecker, D. Pham, R. Burn +6
State-of-the-art planet formation models are now capable of accounting for the full spectrum of known planet types. This comes at the cost of increasing complexity of the models, w…
Atmospheric Rossiter-McLaughlin effect and transmission spectroscopy of WASP-121b with ESPRESSO
F. Borsa, R. Allart, N. Casasayas-Barris +41
WASP-121b is one of the most studied Ultra-hot Jupiters: many recent analyses of its atmosphere report interesting features at different wavelength ranges. In this paper we analyze…
Planetesimal fragmentation and giant planet formation: the role of planet migration
O. M. Guilera, D. Swoboda, Y. Alibert +3
In the standard model of core accretion, the cores of the giant planets form by the accretion of planetesimals. In this scenario, the evolution of the planetesimal population plays…
Grain opacity and the bulk composition of extrasolar planets. I. Results from scaling the ISM opacity
C. Mordasini, H. Klahr, Y. Alibert +2
The opacity due to grains in the envelope of a protoplanet regulates the accretion rate of gas during formation, thus the final bulk composition of planets with primordial H/He is…
Planet Population Synthesis
W. Benz, S. Ida, Y. Alibert +2
With the increasing number of exoplanets discovered, statistical properties of the population as a whole become unique constraints on planet formation models provided a link betwee…
Impacts of planet migration models on planetary populations. Effects of saturation, cooling and stellar irradiation
K. -M. Dittkrist, C. Mordasini, H. Klahr +2
Context: Several recent studies have found that planet migration in adiabatic discs differs significantly from migration in isothermal discs. Depending on the thermodynamic conditi…
A Community Science Case for E-ELT HIRES
R. Maiolino, M. Haehnelt, M. T. Murphy +57
Building on the experience of the high-resolution community with the suite of VLT high-resolution spectrographs, which has been tremendously successful, we outline here the (scienc…
Planet formation models: the interplay with the planetesimal disc
A. Fortier, Y. Alibert, F. Carron +2
According to the sequential accretion model, giant planet formation is based first on the formation of a solid core which, when massive enough, can gravitationally bind gas from th…
Extrasolar planet population synthesis IV. Correlations with disk metallicity, mass and lifetime
C. Mordasini, Y. Alibert, W. Benz +2
Context. This is the fourth paper in a series showing the results of planet population synthesis calculations. Aims. Our goal in this paper is to systematically study the effects o…
Theory of planet formation and comparison with observation: Formation of the planetary mass-radius relationship
C. Mordasini, Y. Alibert, W. Benz +1
The planetary mass-radius diagram is an observational result of central importance to understand planet formation. We present an updated version of our planet formation model based…
Application of recent results on the orbital migration of low mass planets: convergence zones
C. Mordasini, K. -M. Dittkrist, Y. Alibert +3
Previous models of the combined growth and migration of protoplanets needed large ad hoc reduction factors for the type I migration rate as found in the isothermal approximation. I…
