Energy, linear and angular momentum of light: what do we measure?
Olivier Emile, Janine Emile
The most commonly observed quantity related to light is its power or equivalently its energy. It can be either measured with a bolometer, a photodiode or estimated with the naked e…
The magnetic fields of intermediate-mass T Tauri stars : I. Magnetic detections and fundamental stellar parameters
Florent Villebrun, Evelyne Alecian, Gaitee Hussain +13
Context. The origin of the fossil magnetic fields detected in 5 to 10% of intermediate-mass main sequence stars is still highly debated. Aims. We want to bring observational constr…
Differential Galois Theory and Isomonodromic Deformations
David Blázquez Sanz, Guy Casale, Juan Sebastián Díaz Arboleda
We present a geometric setting for the differential Galois theory of -invariant connections with parameters. As an application of some classical results on differential algebrai…
Mass, radius, and composition of the transiting planet 55 Cnc e : using interferometry and correlations --- A quick update
Aurélien Crida, Roxanne Ligi, Caroline Dorn +2
In a recent paper (Crida et al. 2018, accepted on April 19), we presented a method to derive the mass and radius of a transiting exoplanet and their intrinsic correlation, that we…
Tracking Position and Orientation through Millimeter Wave Lens MIMO in 5G Systems
Arash Shahmansoori, Bernard Uguen, Giuseppe Destino +2
Millimeter wave signals and large antenna arrays are considered enabling technologies for future 5G networks. Despite their benefits for achieving high data rate communications, th…
Almost sure convergence on chaoses
Guillaume Poly, Guangqu Zheng
We present several new phenomena about almost sure convergence on homogeneous chaoses that include Gaussian Wiener chaos and homogeneous sums in independent random variables. Concr…
Lattice dynamics of the cluster chain compounds M2Mo6Se6
Liam Gannon, Lilia Boeri, Christopher A. Howard +6
The lattice dynamics of members of the M2Mo6Se6 family of materials with guest ions M = K, Rb, Cs, In, and Tl has been studied using inelastic x-ray scattering and Raman spectrosco…
Non uniform rotating vortices and periodic orbits for the two-dimensional Euler Equations
Claudia García, Taoufik Hmidi, Juan Soler
This paper concerns the study of some special ordered structures in turbulent flows. In particular, a systematic and relevant methodology is proposed to construct non trivial and n…
Modular invariants for genus 3 hyperelliptic curves
Sorina Ionica, Pinar Kilicer, Kristin Lauter +4
In this article we prove an analogue of a theorem of Lachaud, Ritzenthaler, and Zykin, which allows us to connect invariants of binary oc-tics to Siegel modular forms of genus 3. W…
Impacts of radiative accelerations on solar-like oscillating main-sequence stars
M. Deal, G. Alecian, Y. Lebreton +5
Chemical element transport processes are among the crucial physical processes needed for precise stellar modelling. Atomic diffusion by gravitational settling nowadays is usually t…
Atomic level structure of Ge-Sb-S glasses: chemical short range order and long Sb-S bonds
Ildikó Pethes, Virginie Nazabal, Julien Ari +7
The structure of GeSbS, GeSbS and GeSbS glasses was investigated by neutron diffraction (ND), X-ray diffraction (XRD)…
Site-Specific Spin Reorientation in Antiferromagnetic State of Quantum System SeCuO
Nikolina Novosel, William Lafargue-Dit-Hauret, Željko Rapljenović +5
We report on the magnetocrystalline anisotropy energy (MAE) and spin reorientation in antiferromagnetic state of spin tetramer system SeCuO observed in torque magnetome…
Boundary effects on the magnetic Hamiltonian dynamics in two dimensions
Tho Nguyen Duc, Nicolas Raymond, San Vu Ngoc
We study the Hamiltonian dynamics of a charged particle submitted to a pure magnetic field in a two-dimensional domain. We provide conditions on the magnetic field in a neighbourho…
Principally polarized squares of elliptic curves with field of moduli equal to Q
Alexandre Gélin, Everett W. Howe, Christophe Ritzenthaler
We give equations for 13 genus-2 curves over , with models over , whose unpolarized Jacobians are isomorphic to the square of an elliptic curve w…
The structure of near stoichiometric Ge-Ga-Sb-S glasses: a reverse Monte Carlo study
Ildikó Pethes, Virginie Nazabal, Radwan Chahal +5
The structure of GeGaSbS and GeGaSbS glasses was investigated by neutron diffraction (ND), X-ray diffraction (XRD), and extende…
Gaia Data Release 2. Summary of the contents and survey properties
Gaia Collaboration, A. G. A. Brown, A. Vallenari +4
We present the second Gaia data release, Gaia DR2, consisting of astrometry, photometry, radial velocities, and information on astrophysical parameters and variability, for sources…
Sylvester double sums, subresultants and symmetric multivariate Hermite interpolation
Marie-Françoise Roy, Aviva Szpirglas
Sylvester doubles sums, introduced first by Sylvester are symmetric expressions of the roots of two polynomials. Sylvester's definition of double sums makes no sense in the presenc…
Microwave generation on an optical carrier in micro-resonator chains
Andrea Armaroli, Patrice Féron, Yannick Dumeige
We consider self-pulsing regimes in chains of Kerr nonlinear optical microresonators. By means of a supermodal diagonalization procedure of the conventional coupled-mode theory in…
Gaia Data Release 2: Mapping the Milky Way disc kinematics
Gaia Collaboration, D. Katz, T. Antoja +12
To illustrate the potential of GDR2, we provide a first look at the kinematics of the Milky Way disc, within a radius of several kiloparsecs around the Sun. We benefit for the firs…
Gaia Data Release 2: Observations of solar system objects
Gaia Collaboration, F. Spoto, P. Tanga +4
The Gaia spacecraft of the European Space Agency (ESA) has been securing observations of solar system objects (SSOs) since the beginning of its operations. Gaia Data Release 2 (DR2…
