Determining the incidence rate of magnetic Scuti candidates with CoRoT
Gautam Paul, Coralie Neiner, Claude Catala +1
Scuti stars are pulsating stars constituting the Scuti instability strip in the Hertzsprung-Russell (HR) diagram, which consists of A and F stars. They are in the transitio…
Asteroseismic modelling of main-sequence solar-like stars and Kepler exoplanet host stars with the FICO procedure I. Catalogue of fundamental stellar properties
Jérôme Bétrisey, Daniel R. Reese, Camilla Pezzotti +2
We present detailed asteroseismic modelling of 95 main-sequence solar-like stars and Kepler exoplanet host stars using the FICO procedure, a three-step method that combines forward…
Tearing Driven Reconnection: Energy Conversion Involving Firehose Kinetic Instabilities (2D Hybrid Möbius Simulations)
Etienne Berriot, Petr Hellinger, Olga Alexandrova +2
This study focuses on energy conversion related to tearing-driven magnetic reconnection in the context of weakly collisional astrophysical plasmas. We present results from a two-di…
Signatures of localised particle acceleration at a global coronal shock wave
C. Cuddy, D. M. Long, M. Nedal +2
Extreme ultraviolet (EUV) waves are global waves in the solar corona which can accelerate particles. The efficiency of the acceleration depends on local plasma characteristics e.g.…
Reconstruction of Cepheid Radial Velocity Curves from the shape of the V-band Light Curves
V. Hocdé, P. Moskalik, N. Nardetto +17
This paper aims to develop the first method to reconstruct the shape of the RV curves of short-period fundamental-mode Cepheids, based exclusively on their pulsation period and the…
Gaia DR3 high radial velocity stars: Genuine fast-moving objects or outliers?
D. Katz, A. Gómez, E. Caffau +39
The third Gaia data release includes 33.8 million radial velocity measurements, extending to a magnitude of G_RVS = 14. To reach this magnitude limit, spectra were processed down t…
