The SPIRou wavelength calibration for precise radial velocities in the near infrared
M. J. Hobson, F. Bouchy, N. J. Cook +8
SPIRou is a near-infrared (nIR) spectropolarimeter at the CFHT, covering the YJHK nIR spectral bands (). We describe the development and current status of th…
The SOPHIE search for northern extrasolar planets XV. A Warm Neptune around the M-dwarf Gl378
M. J. Hobson, X. Delfosse, N. Astudillo-Defru +31
We present the detection of a Warm Neptune orbiting the M-dwarf Gl378, using radial velocity measurements obtained with the SOPHIE spectrograph at the Observatoire de Haute-Provenc…
PSYM-WIDE: a survey for large-separation planetary-mass companions to late spectral type members of young moving groups
Marie-Eve Naud, Étienne Artigau, René Doyon +5
We present the results of a direct-imaging survey for very large separation (100 au), companions around 95 nearby young K5-L5 stars and brown dwarfs. They are high-likelihood ca…
17 new very low-mass members in Taurus. The brown dwarf deficit revisited
S. Guieu, C Dougados, J. L Monin +2
Recent studies of the substellar population in the Taurus cloud have revealed a deficit of brown dwarfs (BD) compared to the Trapezium cluster population (Briceno et al 1998; Luhma…
Circumbinary disks around T Tauri stars: HST/NICMOS near-infrared images and polarimetric maps
G. Duchene, J. Silber, F. Menard +1
We have obtained new near-infrared images of both GG Tau and UY Aur circumbinary disks with the polarimetric modes of NICMOS aboard the Hubble Space Telescope. The 1 micron intensi…
Accretion in Taurus PMS binaries: a spectroscopic study
Gaspard Duchene, Jean-Louis Monin, Jerome Bouvier +1
We present low-resolution optical spectra of each component of 10 T Tauri (TT) binary systems with separations ranging from 0.9" to 3.5" and located in the Taurus star-forming regi…
