Radiative hydrodynamics simulations of red supergiant stars. III. Spectro-photocentric variability, photometric variability, and consequences on Gaia measurements
A. Chiavassa, E. Pasquato, A. Jorissen +8
Context. It has been shown that convection in red supergiant stars gives rise to large granules causing surface inhomogeneities together with shock waves in the photosphere. The re…
Imaging the spinning gas and dust in the disc around the supergiant A[e] star HD62623
Florentin Millour, Anthony Meilland, Olivier Chesneau +5
Context. To progress in the understanding of evolution of massive stars one needs to constrain the mass-loss and determine the phenomenon responsible for the ejection of matter an…
Deformation of a flexible polymer in a random flow with long correlation time
Stefano Musacchio, Dario Vincenzi
The effects induced by long temporal correlations of the velocity gradients on the dynamics of a flexible polymer are investigated by means of theoretical and numerical analysis of…
Sensitivity Studies for Third-Generation Gravitational Wave Observatories
S. Hild, M. Abernathy, F. Acernese +136
Advanced gravitational wave detectors, currently under construction, are expected to directly observe gravitational wave signals of astrophysical origin. The Einstein Telescope, a…
Effect of turbulent fluctuations on the drag and lift forces on a towed sphere and its boundary layer
Holger Homann, Jérémie Bec, Rainer Grauer
The impact of turbulent fluctuations on the forces exerted by a fluid on a towed spherical particle is investigated by means of high-resolution direct numerical simulations. The me…
Prym varieties of spectral covers
Tamás Hausel, Christian Pauly
Given a possibly reducible and non-reduced spectral cover X over a smooth projective complex curve C we determine the group of connected components of the Prym variety Prym(X/C). A…
Universality of scaling and multiscaling in turbulent symmetric binary fluids
Samriddhi Sankar Ray, Abhik Basu
We elucidate the universal scaling and multiscaling properties of the nonequilibrium steady states (NESS) in a driven symmetric binary fluid (SBF) mixture in its homogeneous miscib…
Longitudinal and Transverse structure functions in high Reynolds-number turbulence
Rainer Grauer, Holger Homann, Jean-Francois Pinton
Using exact relations between velocity structure functions (Hill, Hill and Boratav, and Yakhot) and neglecting pressure contributions in a first approximation, we obtain a closed s…
Microwave realization of quasi one-dimensional systems with correlated disorder
O. Dietz, U. Kuhl, H. -J. Stoeckmann +2
A microwave setup for mode-resolved transport measurement in quasi-one-dimensional (quasi-1D) structures is presented. We will demonstrate a technique for direct measurement of the…
A profile decomposition approach to the Navier-Stokes regularity criterion
Isabelle Gallagher, Gabriel S. Koch, Fabrice Planchon
In this paper we continue to develop an alternative viewpoint on recent studies of Navier-Stokes regularity in critical spaces, a program which was started in the recent work by C.…
On the theory of cavities with point-like perturbations. Part II: Rectangular cavities
T. Tudorovskiy, U. Kuhl, H-J. Stoeckmann
We consider an application of a general theory for cavities with point-like perturbations for a rectangular shape. Hereby we concentrate on experimental wave patterns obtained for…
Nonsymmetrized Hyperspherical Harmonics approach to A=6 system
Mario Gattobigio, Alejandro Kievsky, Michele Viviani
The Hyperspherical Harmonics basis, without a previous symmetrization step, is used to calculate binding energies of the nuclear A=6 systems using a version of the Volkov potential…
Nonstationary Regime of Random Lasers
Jonathan Andreasen, Patrick Sebbah, Christian Vanneste
A numerical study is presented of one-dimensional and two-dimensional random lasers as a function of the pumping rate above the threshold for lasing. Depending on the leakiness of…
A disk inside the bipolar planetary nebula M2-9
Foteini Lykou, Olivier Chesneau, Albert A. Zijlstra +4
Bipolarity in proto-planetary and planetary nebulae is associated with events occurring in or around their cores. Past infrared observations have revealed the presence of dusty str…
A2163: Merger events in the hottest Abell galaxy cluster II. Subcluster accretion with galaxy-gas separation
H. Bourdin, M. Arnaud, P. Mazzotta +7
Located at z = 0.203, A2163 is a rich galaxy cluster with an intra-cluster medium (ICM) that exhibits extraordinary properties, including an exceptionally high X-ray luminosity, av…
Conditional Eulerian and Lagrangian velocity increment statistics of fully developed turbulent flow
Holger Homann, Daniel Schulz, Rainer Grauer
Conditional statistics of homogeneous isotropic turbulent flow is investigated by means of high-Reynolds number direct numerical simulations performed with collocation poi…
The Rayleigh-Schrödinger perturbation series of quasi-degenerate systems
Christian Brouder, Gérard H. E. Duchamp, Frédéric Patras +1
We present the first representation of the general term of the Rayleigh-Schrödinger series for quasidegenerate systems. Each term of the series is represented by a tree and there i…
Cold uniform spherical collapse revisited
M. Joyce, B. Marcos, F. Sylos Labini
We report results of a study of the Newtonian dynamics of N self-gravitating particles which start in a quasi-uniform spherical configuration, without initial velocities. These ini…
Near-Infrared Multi-Band Photometry of the Substellar Companion GJ 758 B
M. Janson, J. Carson, C. Thalmann +46
GJ 758 B is a cold (~600K) companion to a Sun-like star at 29 AU projected separation, which was recently detected with high-contrast imaging. Here we present photometry of the com…
Search for Gravitational Wave Bursts from Six Magnetars
J. Abadie, B. P. Abbott, R. Abbott +765
Soft gamma repeaters (SGRs) and anomalous X-ray pulsars (AXPs) are thought to be magnetars: neutron stars powered by extreme magnetic fields. These rare objects are characterized b…

Let be a finite alphabet, equipped with the shift action, and the simplex of shift-invariant measures on . We study the relation between…
Almost reducibility for finitely differentiable SL(2,R)-valued quasi-periodic cocycles
Claire Chavaudret
Quasi-periodic cocycles with a diophantine frequency and with values in SL(2,R) are shown to be almost reducible as long as they are close enough to a constant, in the topology of…
