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…
