The magnetic obliquity of accreting T Tauri stars

Autor: Jerome Bouvier, Pauline McGinnis, F. Gallet

Publikováno v: Monthly Notices of the Royal Astronomical Society

Classical T Tauri stars (CTTS) accrete material from their discs through their magnetospheres. The geometry of the accretion flow strongly depends on the magnetic obliquity, i.e., the angle between the rotational and magnetic axes. We aim at deriving

Tidal Dissipation In Rotating Low Mass Stars: Implications For The Orbital Evolution Of Close In Planets

Autor: F. Gallet, E. Bolmont, S. Mathis, C. Charbonnel, L. Amard, Y. Alibert

Publikováno v: EWASS Special Session 4 (2017): Star-planet interactions (EWASS-SS4-2017), held 26-30 June, 2017 in Prague, Czech Republic. Online at http://eas.unige.ch/EWASS2017/session.jsp?id=SS4, id. 10

Close-in planets represent a large fraction of the population of conVrmed exoplanets. To understand the dynamical evolution of these planets, star-planet interactions must be taken into account. In particular, the dependence of the tidal interactions

Publikováno v: Astronomy & Astrophysics. 631:A77

Aims.We present an extended grid of state-of-the art stellar models for low-mass stars including updated physics (nuclear reaction rates, surface boundary condition, mass-loss rate, angular momentum transport, rotation-induced mixing, and torque pres

Square lattice photonic-crystal collimator

Autor: Lijun Wu, J.-F. Gallet, Michael Mazilu, Thomas F. Krauss

Publikováno v: Photonics and Nanostructures - Fundamentals and Applications. 1:31-36

The anomalous dispersion of planar photonic crystals (PhCs) near the dielectric band edge is utilised to control the wavelength-dependent propagation of light. Light beams with up to ±10° divergence were cleanly collimated over a 40 nm (1260–1300
