Single-photon Sagnac interferometer
Guillaume Bertocchi, Olivier Alibart, Daniel Barry Ostrowsky +2
We present the first experimental demonstration of the optical Sagnac effect at the single-photon level. Using a high quality guided-wave heralded single- photon source at 1550 nm…
Origin of the peculiar eccentricity distribution of the inner cold Kuiper belt
A. Morbidelli, H. S. Gaspar, D. Nesvorny
Dawson and Murray-Clay (2012) pointed out that the inner part of the cold population in the Kuiper belt (that with semi major axis a<43.5 AU) has orbital eccentricities significant…
The Gaia-ESO Survey: Abundance ratios in the inner-disk open clusters Trumpler 20, NGC 4815, NGC 6705
L. Magrini, S. Randich, D. Romano +50
Open clusters are key tools to study the spatial distribution of abundances in the disk and their evolution with time. Using the first release of stellar parameters and abundances…
Measurement of acoustic glitches in solar-type stars from oscillation frequencies observed by Kepler
A. Mazumdar, M. J. P. F. G. Monteiro, J. Ballot +15
For the very best and brightest asteroseismic solar-type targets observed by Kepler, the frequency precision is sufficient to determine the acoustic depths of the surface convectiv…
The Gaia-ESO Survey: Reevaluation of the parameters of the open cluster Trumpler 20 using photometry and spectroscopy
P. Donati, T. Cantat-Gaudin, A. Bragaglia +34
Trumpler 20 is an old open cluster (OC) located toward the Galactic centre, at about 3 kpc from the Sun and 7 kpc from the Galactic centre. Its position makes this cluster pa…
A new procedure for defining a homogenous line-list for solar-type stars
S. G. Sousa, N. C. Santos, V. Adibekyan +9
Context. The homogenization of the stellar parameters is an important goal for large observational spectroscopic surveys, but it is very difficult to achieve it because of the dive…
Terrestrial Planet Formation in a protoplanetary disk with a local mass depletion: A successful scenario for the formation of Mars
A. Izidoro, N. Haghighipour, O. C. Winter +1
Models of terrestrial planet formation for our solar system have been successful in producing planets with masses and orbits similar to those of Venus and Earth. However, these mod…
Geochemical and planetary dynamical views on the origin of Earth's atmosphere and oceans
Nicolas Dauphas, Alessandro Morbidelli
Earth's volatile elements (H, C, and N) are essential to maintaining habitable conditions for metazoans and simpler life forms. However, identifying the sources (comets, meteorites…
Subcritical mirror structures in an anisotropic plasma
E. A. Kuznetsov, T. Passot, V. P. Ruban +1
Based on Grad-Shafranov-like equations, a gyrotropic plasma where the pressures in the static regime are only functions of the amplitude of the local magnetic field is shown to be…
Magnetic activity of F stars observed by Kepler
S. Mathur, R. A. Garcia, J. Ballot +6
The study of stellar activity is important because it can provide new constraints for dynamo models, when combined with surface rotation rates and the depth of the convection zone.…
On the cosmic convergence mechanism of the massless dilaton
Olivier Minazzoli
The converging mechanism discussed in [Damour & Nordtvedt, Physical Review Letters,70,15] for scalar-tensor theories has been applied to dilaton-like theories in several subsequent…
Spectral properties of microwave graphs with local absorption
M. Allgaier, S. Gehler, S. Barkhofen +2
The influence of absorption on the spectra of microwave graphs has been studied experimentally. The microwave networks were made up of coaxial cables and T junctions. First, absorp…
Semiclassical pair production rate for time-dependent electrical fields with more than one component: -WKB-approach and world-line instantons
Eckhard Strobel, She-Sheng Xue
We present an analytic calculation of the semiclassical electron-positron pair creation rate by time-dependent electrical fields. We use two methods, first the imaginary time metho…
Non equilibrium phase transition with gravitational-like interaction in a cloud of cold atoms
Julien Barré, Bruno Marcos, David Wilkowski
We propose to use a cloud of laser cooled atoms in a quasi two dimensional trap to investigate a non equilibrium collapse phase transition in presence of gravitational-like interac…
Harmonic Maps to Buildings and Singular Perturbation Theory
Ludmil Katzarkov, Alexander Noll, Pranav Pandit +1
The notion of a universal building associated with a point in the Hitchin base is introduced. This is a building equipped with a harmonic map from a Riemann surface that is initial…
A non-grey analytical model for irradiated atmospheres. I: Derivation
Vivien Parmentier, Tristan Guillot
Context. Semi-grey atmospheric models (with one opacity for the visible and one opacity for the infrared) are useful to understand the global structure of irradiated atmospheres, t…
Symmetry Breaking in d-Dimensional Self-gravitating Systems
Renato Pakter, Bruno Marcos, Yan Levin
Systems with long-range interactions, such as self-gravitating clusters and magnetically confined plasmas, do not relax to the usual Boltzmann-Gibbs thermodynamic equilibrium, but…
Revisited fluorine abundances in the globular cluster M22 (NGC 6656)
P. de Laverny, A. Recio-Blanco
Fluorine is a fairly good tracer of formation histories of multiple stellar populations in globular clusters as already revealed by several studies. Large variations in fluorine ab…
Two dimensional Leidenfrost Droplets in a Hele Shaw Cell
Franck Celestini, Thomas Frisch, A. Cohen +3
We experimentally and theoretically investigate the behavior of Leidenfrost droplets inserted in a Hele-Shaw cell. As a result of the confinement from the two surfaces, the droplet…
Axial rotation and turbulence of RR ab stars: the Peterson Conundrum revisited
G. W. Preston, M. Chadid
We calibrate and then use the relation between equivalent width (EW) and full-width-half-maximum (FWHM) of metallic absorption lines in the spectra of RR Lyrae stars to estimate a…
Predictions for the Detection of Earth and Mars Trojan Asteroids by the Gaia satellite
M. Todd, P. Tanga, D. M. Coward +1
The European Space Agency Gaia satellite, planned for launch in late 2013, will perform systematic astrometric observations of the whole sky over a five year period. During this mi…
Discovery of possible molecular counterparts to the infrared Double Helix Nebula in the Galactic center
R. Enokiya, K. Torii, M. Schultheis +23
We have discovered two molecular features at radial velocities of -35 km/s and 0 km/s toward the infrared Double Helix Nebula (DHN) in the Galactic center with NANTEN2. The two fea…

Induced Gravitational Collapse in the BATSE era: the case of GRB 970828
R. Ruffini, Jorge A. Rueda, C. Barbarino +8
Following the recently established "Binary-driven HyperNova" (BdHN) paradigm, we here interpret GRB 970828 in terms of the four episodes typical of such a model. The "Episode 1", u…
