Investigating the young AU~Mic system with SPIRou: large-scale stellar magnetic field and close-in planet mass
Baptiste Klein, Jean-François Donati, Claire Moutou +12
We present a velocimetric and spectropolarimetric analysis of 27 observations of the 22-Myr M1 star AU Microscopii (Au Mic) collected with the high-resolution (0.98-2.35 …
The large-scale magnetic field of Proxima Centauri near activity maximum
Baptiste Klein, Jean-François Donati, Élodie M. Hébrard +5
We report the detection of a large-scale magnetic field at the surface of the slowly-rotating fully-convective M dwarf Proxima Centauri. Ten circular polarization spectra, collecte…
The distribution of dark matter and gas spanning six megaparsecs around the post-merger galaxy cluster MS0451-03
Sut-Ieng Tam, Mathilde Jauzac, Richard Massey +11
Using the largest mosaic of Hubble Space Telescope images around a galaxy cluster, we map the distribution of dark matter throughout a Mpc area centred on the…
Spin-orbit alignment and magnetic activity in the young planetary system AU Mic
E. Martioli, G. Hebrard, C. Moutou +21
We present high resolution near-infrared spectropolarimetric observations using the SPIRou instrument at CFHT during a transit of the recently detected young planet AU Mic b, with…
Galaxy cluster cores as seen with VLT/MUSE: new strong-lensing analyses of RX J2129.4+0009, MS 0451.6-0305 & MACSJ2129.4-0741
Mathilde Jauzac, Baptiste Klein, Jean-Paul Kneib +4
We present strong-lensing analyses of three galaxy clusters, RXJ2129.4+0009 (z=0.235), MS0451.6-0305 (z=0.55), and MACSJ2129.4-0741 (z=0.589), using the powerful combination of Hub…
Simulated mass measurements of the young planet K2-33b
Baptiste Klein, Jean-François Donati
In this paper, we carry out simulations of radial velocity (RV) measurements of the mass of the 8-11 Myr Neptune-sized planet K2-33b using high-precision near infrared velocimeters…
