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…
Do non-dipolar magnetic fields contribute to spin-down torques?
Victor See, Sean P. Matt, Adam J. Finley +14
Main sequence low-mass stars are known to spin-down as a consequence of their magnetised stellar winds. However, estimating the precise rate of this spin-down is an open problem. T…
Estimating magnetic filling factors from Zeeman-Doppler magnetograms
Victor See, Sean P. Matt, Colin P. Folsom +15
Low-mass stars are known to have magnetic fields that are believed to be of dynamo origin. Two complementary techniques are principally used to characterise them. Zeeman-Doppler im…
Predictions of planet detections with near infrared radial velocities in the up-coming SPIRou Legacy Survey-Planet Search
Ryan Cloutier, Étienne Artigau, Xavier Delfosse +8
The SPIRou near infrared spectro-polarimeter is destined to begin science operations at the Canada-France-Hawaii Telescope in mid-2018. One of the instrument's primary science goal…
SPIRou Input Catalog: Activity, Rotation and Magnetic Field of Cool Dwarfs
C. Moutou, E. M. Hebrard, J. Morin +7
Based on optical high-resolution spectra obtained with CFHT/ESPaDOnS, we present new measurements of activity and magnetic field proxies of 442 low-mass K5-M7 dwarfs. The objects w…
A deep staring campaign in the Sigma Orionis cluster. Variability in substellar members
P. Elliott, A. Scholz, R. Jayawardhana +2
Deep optical imaging is used to study time-domain properties of young brown dwarfs in sigma Orionis over typical rotational time-scales and to search for new substellar and planeta…
