A rich population of free-floating planets in the Upper Scorpius young stellar association

Núria Miret-Roig, Hervé Bouy, Sean N. Raymond +9

The nature and origin of free-floating planets (FFPs) are still largely unconstrained because of a lack of large homogeneous samples to enable a statistical analysis of their prope…

Anisotropic cosmic-ray diffusion in isotropic Kolmogorov turbulence

P. Reichherzer, J. Becker Tjus, E. G. Zweibel +2

Understanding the time scales for diffusive processes and their degree of anisotropy is essential for modelling cosmic-ray transport in turbulent magnetic fields. We show that the…

An intersection-theoretic proof of the Harer-Zagier formula

Alessandro Giacchetto, Danilo Lewański, Paul Norbury

We provide an intersection-theoretic formula for the Euler characteristic of the moduli space of smooth curves. This formula reads purely in terms of Hodge integrals and, as a coro…

The extended atmosphere and circumstellar environment of the cool evolved star VX Sagittarii as seen by MATISSE

A. Chiavassa, K. Kravchenko, M. Montargès +50

Context. VX Sgr is a cool, evolved, and luminous red star whose stellar parameters are difficult to determine, which affects its classification. Aims. We aim to spatially resolve t…

Multi-scale simulation of the adsorption of lithium ion on graphite surface: from Quantum Monte Carlo to Molecular Density Functional Theory

Michele Ruggeri, Kyle Reeves, Tzu-Yao Hsu +3

The structure of the double-layer formed at the surface of carbon electrodes is governed by the interactions between the electrode and the electrolyte species. However, carbon is n…

Artificial neural network modelling of generalised parton distributions

H. Dutrieux, O. Grocholski, H. Moutarde +1

We discuss the use of machine learning techniques in effectively nonparametric modelling of generalised parton distributions (GPDs) in view of their future extraction from experime…
