Sticky elastic collisions
Jeremie Bec, Stefano Musacchio, Samriddhi Sankar Ray
The effects of purely elastic collisions on the dynamics of heavy inertial particles is investigated in a three-dimensional random incompressible flow. It is shown that the statist…
Distant galaxy clusters in the XMM Large Scale Structure survey
J. P. Willis, N. Clerc, M. N. Bremer +12
(Abridged) Distant galaxy clusters provide important tests of the growth of large scale structure in addition to highlighting the process of galaxy evolution in a consistently defi…
Spiral Arms in the Asymmetrically Illuminated Disk of MWC 758 and Constraints on Giant Planets
C. A. Grady, T. Muto, J. Hashimoto +71
We present the first near-IR scattered light detection of the transitional disk associated with the Herbig Ae star MWC 758 using data obtained as part of the Strategic Exploration…
PS1-10jh - a tidal disruption event with an extremely low disk temperature
Matias Montesinos, J. A. de Freitas Pacheco
The cooler than expected optical-UV transient PS1-10jh detected by the Pan-STARRS1 survey is probably related to a tidal disruption event in which a He-rich stellar core remnant is…
VISIR-VLT high resolution study of the extended emission of four obscured post-AGB candidates
M. W. Blanco, M. A. Guerrero, G. Ramos-Larios +4
The onset of the asymmetry of planetary nebulae (PNe) is expected to occur during the late Asymptotic Giant Branch (AGB) and early post-AGB phases of low- and intermediate-mass sta…
Constraining magnetic-activity modulations in 3~solar-like stars observed by CoRoT and NARVAL
S. Mathur, R. A. Garcia, A. Morgenthaler +5
Stellar activity cycles are the manifestation of dynamo process running in the stellar interiors. They have been observed during years to decades thanks to the measurement of stell…
First stars XVI. STIS/HST abundances of heavy-elements in the uranium-rich star CS 31082-001
C. Siqueira Mello, M. Spite, B. Barbuy +14
Detailed abundances of the elements produced by r-process nucleosynthesis in various circumstances are our best observational clues to their origin, since the site(s) of r-element…
Stellar irradiated discs and implications on migration of embedded planets I: equilibrium discs
Bertram Bitsch, Aurélien Crida, Alessandro Morbidelli +2
The strength and direction of migration of low mass planets depends on the disc's thermodynamics. In discs where the viscous heating is balanced by radiative transport, the migrati…
Experimental Observation of the Spectral Gap in Microwave n-Disk Systems
S. Barkhofen, T. Weich, A. Potzuweit +3
Symmetry reduced three-disk and five-disk systems are studied in a microwave setup. Using harmonic inversion the distribution of the imaginary parts of the resonances is determined…
Universal nature and finite-range corrections in elastic atom-dimer scattering below the dimer breakup threshold
A. Kievsky, M. Gattobigio
We investigate universal behavior in elastic atom-dimer scattering below the dimer breakup threshold calculating the atom-dimer effective-range function . Using the He-He…
Collisional relaxation of two-dimensional self-gravitating systems
B. Marcos
Systems with long range interactions present generically the formation of quasi-stationary long-lived non-equilibrium states. These states relax to Boltzmann equilibrium following…
Fast accurate computation of the fully nonlinear solitary surface gravity waves
Didier Clamond, Denys Dutykh
In this short note, we present an easy to implement and fast algorithm for the computation of the steady solitary gravity wave solution of the free surface Euler equations in irrot…
Generalized Cayley Graphs and Cellular Automata over them
Pablo Arrighi, Simon Martiel, Vincent Nesme
Cayley graphs have a number of useful features: the ability to graphically represent finitely generated group elements and their relations; to name all vertices relative to a point…
Efimov Physics in small bosonic clusters
M. Gattobigio, A. Kievsky, M. Viviani
We study small clusters of bosons, , characterized by a resonant interaction. Firstly, we use a soft-gaussian interaction that reproduces the values of the dimer bindi…
Existence of quasipatterns solutions of the Swift-Hohenberg equation
Boele Braaksma, Gérard Iooss, Laurent Stolovitch
We consider the steady Swift - Hohenberg partial differential equation. It is a one-parameter family of PDE on the plane, modeling for example Rayleigh - Bénard convection. For val…
Characterization of bent crystals for Laue lenses
V. Liccardo, E. Virgilli, F. Frontera +1
In the context of the LAUE project devoted to build a long focal-length focusing optics for soft -ray astronomy (80 - 600 keV), we present the results of reflectivity measuremen…
Expected performance of a Laue lens based on bent crystals
Vineeth Valsan, Filippo Frontera, Enrico Virgilli +1
In the context of the LAUE project devoted to build a long focal length focusing optics for soft gamma-ray astronomy (70/100 keV to 600 keV), we present results of simulation of…
Development status of the LAUE project
F. Frontera, E. Virgilli, V. Liccardo +18
We present the status of LAUE, a project supported by the Italian Space Agency (ASI), and devoted to develop Laue lenses with long focal length (up to 100 meters), for hard X--/sof…
IRIS: A Generic Three-Dimensional Radiative Transfer Code
L. Ibgui, I. Hubeny, T. Lanz +1
We present IRIS, a new generic three-dimensional (3D) spectral radiative transfer code that generates synthetic spectra, or images. It can be used as a diagnostic tool for comparis…
Direct Imaging Discovery of a `Super-Jupiter' Around the late B-Type Star Kappa And
J. Carson, C. Thalmann, M. Janson +52
We present the direct imaging discovery of an extrasolar planet, or possible low-mass brown dwarf, at a projected separation of 55 +/- 2 AU (1.058 +/- 0.007 arcsec) from the B9-typ…
Extracting interstellar diffuse absorption bands from cool star spectra: Application to bulge clump giants in Baade's window
Hui-Chen Chen, Rosine Lallement, Carine Babusiaux +3
Interstellar diffuse bands are usually extracted from hot star spectra because they are characterized by smooth continua. It introduces a strong limitation on the number of availab…
