Super-harmonically resonant swirling waves in longitudinally forced circular cylinders
François Gallaire, Alessandro Bongarzone, Alice Evelyne Julienne Marcotte
Resonant sloshing in circular cylinders was studied by Faltinsen et al. (J. Fluid Mech., vol. 804, 2016, pp. 608-645), whose theory was used to describe steady-state resonant waves due to a time-harmonic container's elliptic orbits. In the limit of longitu ...
CAMBRIDGE UNIV PRESS2023Can dd excitations mediate pairing?
Christophe Berthod, Francesco Barantani
The Cu-3d states in the high-T-c cuprates are often described as a single band of 3d(x2-y2) states, with the other four 3d states having about 2 to 3 eV higher energy due to the lower-than-octahedral crystal field at the copper sites. However, excitations ...
Amsterdam2023Gaia Focused Product Release: Asteroid orbital solution: Properties and assessment
Stephan Morgenthaler, Shuangqing Liao
Context. We report the exploitation of a sample of Solar System observations based on data from the third Gaia Data Release (Gaia DR3) of nearly 157 000 asteroids. It extends the epoch astrometric solution over the time coverage planned for the Gaia DR4, w ...
Les Ulis Cedex A2023Discovery of a Binary-origin Classical Cepheid in a Binary System with a 59 day Orbital Period
We report the discovery of a surprising binary configuration of the double-mode Cepheid OGLE-LMC-CEP-1347 pulsating in the first (P-1= 0.690 days) and second-overtone (P-2= 0.556 days) modes. The orbital period (P-orb= 59 days) of the system is five times ...
Bristol2022Whirling instability of an eccentric coated fibre
François Gallaire, Edouard Boujo, Shahab Eghbali, Ludovic Pierre Gustave Keiser
We study a gravity-driven viscous flow coating a vertical cylindrical fibre. The destabilisation of a draining liquid column into a downward moving train of beads has been linked to the conjunction of the Rayleigh-Plateau and Kapitza instabilities in the l ...
CAMBRIDGE UNIV PRESS2022Capture system adapted to capture orbital objects, in particular for deorbiting purposes
Pierre-Alain Mäusli, Muriel Richard, Michaël Pellet
There is described a capture system (100) adapted to capture orbital objects (2000), in particular for deorbiting purposes. The capture system (110) comprises (i) a deployable capture structure (110) designed to be deployable between a standby configuratio ...
2020Sun-synchronous repeat ground tracks and other useful orbits for future space missions
Sun Hee Kim, Luzius Gregor Kronig
The development of oceanography and meteorology has greatly benefited from satellite-based data of Earth's atmosphere and ocean. Traditional Earth observation missions have utilised Sun-synchronous orbits with repeat ground tracks due to their advantages i ...
