Large-scale magnetic topologies of late M dwarfs⋆
We present here the final results of the first spectropolarimetric survey of a small sample of active M dwarfs, aimed at providing observational constraints on dynamo action on both sides of the… Expand
Magnetospheric accretion on the T Tauri star BP Tauri
From observations collected with the ESPaDOnS and NARVAL spectropolarimeters, we report the detection of Zeeman signatures on the classical T Tauri star (cTTS) BP Tau. Circular polarization… Expand
Toroidal versus poloidal magnetic fields in Sun-like stars: a rotation threshold
From a set of stellar spectropolarimetric observations, we report the detection of surface magnetic fields in a sample of four solar-type stars, namely HD 73350, HD 76151, HD 146233 (18 Sco) and HD… Expand
Large-scale magnetic topologies of early M dwarfs
We present here additional results of a spectropolarimetric survey of a small sample of stars ranging from spectral type M0 to M8 aimed at investigating observationally how dynamo processes operate… Expand
Weak magnetic fields in Ap/Bp stars - Evidence for a dipole field lower limit and a tentative interp
Aims. We investigated a sample of 28 well-known spectroscopically-identified magnetic Ap/Bp stars, with weak, poorly-determined or previously undetected magnetic fields. The aim of this study is to… Expand
First evidence of a magnetic field on Vega Towards a new class of magnetic A-type stars ⋆
Aims. We report the detection of a magnetic field on Vega through spe ctropolarimetric observations. Methods. We acquired 257 Stokes V, high signal-to-noise and high-resolution echelle spectra during… Expand
A BCool magnetic snapshot survey of solar-type stars
We present the results of a major high-resolution spectropolarimetric BCool project magnetic survey of 170 solar-type stars. Surface magnetic fields were detected on 67 stars, with 21 classified as… Expand
Magnetospheric accretion and spin‐down of the prototypical classical T Tauri star AA Tau
From observations collected with the ESPaDOnS spectropolarimeter at the Canada-France-Hawaii Telescope (CFHT) and with the NARVAL spectropolarimeter at the Telescope Bernard Lyot (TBL), we report the… Expand
Detection of a weak surface magnetic field on Sirius A: are all tepid stars magnetic?
Aims. We aim at a highly sensitive search for weak magnetic fields in main sequence stars of intermediate mass, by scanning classes of stars with no previously reported magnetic members. After… Expand
The Magnetic Fields at the Surface of Active Single G-K Giants
We investigate the magnetic field at the surface of 48 red giants selected as promising for detection of Stokes V Zeeman signatures in their spectral lines. We use the spectropolarimeters Narval and… Expand
