The classical T Tauri star CI Tau observed with SPIRou: magnetospheric accretion and planetary formation
J. -F. Donati, B. Finociety, P. I. Cristofari +15
We report new observations of the classical T~Tauri star CI~Tau with the SPIRou near-infrared spectropolarimeter and velocimeter at the Canada-France-Hawaii Telescope (CFHT) in lat…
Measuring small-scale magnetic fields of 44 M dwarfs from SPIRou spectra with ZeeTurbo
P. I. Cristofari, J. -F. Donati, C. Moutou +11
We present the results of an analysis aimed at probing the small-scale magnetic fields of M dwarfs observed with SPIRou, the nIR high-resolution spectro-polarimeter installed at th…
Monitoring the young planet host V1298 Tau with SPIRou: planetary system and evolving large-scale magnetic field
B. Finociety, J. -F. Donati, P. I. Cristofari +15
We report results of a spectropolarimetric monitoring of the young Sun-like star V1298~Tau based on data collected with the near-infrared spectropolarimeter SPIRou at the Canada-Fr…
Comprehensive High-resolution Chemical Spectroscopy of Barnard's Star with SPIRou
Farbod Jahandar, René Doyon, Étienne Artigau +17
Determination of fundamental parameters of stars impacts all fields of astrophysics, from galaxy evolution to constraining the internal structure of exoplanets. This paper presents…
Magnetic fields & rotation periods of M dwarfs from SPIRou spectra
J. -F. Donati, L. T. Lehmann, P. I. Cristofari +17
We present near-infrared spectropolarimetric observations of a sample of 43 weakly- to moderately-active M dwarfs, carried with SPIRou at the Canada-France-Hawaii Telescope in the…
OGLE-2017-BLG-1186: first application of asteroseismology and Gaussian processes to microlensing
Shun-Sheng Li, Weicheng Zang, Andrzej Udalski +102
We present the analysis of the event OGLE-2017-BLG-1186 from the 2017 Spitzer microlensing campaign. This is a remarkable microlensing event because its source is photometrically b…
Observational calibration of the projection factor of Cepheids - III. The long-period Galactic Cepheid RS Puppis
Pierre Kervella, Boris Trahin, Howard E. Bond +10
The projection factor (p-factor) is an essential component of the classical Baade-Wesselink (BW) technique, that is commonly used to determine the distances to pulsating stars. It…
The long-period Galactic Cepheid RS Puppis - III. A geometric distance from HST polarimetric imaging of its light echoes
P. Kervella, H. E. Bond, M. Cracraft +8
As one of the most luminous Cepheids in the Milky Way, the 41.5-day RS Puppis is an analog of the long-period Cepheids used to measure extragalactic distances. An accurate distance…
