Non coeval young multiple systems? On the pairing of protostars and T Tauri stars
Gaspard Duchene, Andrea Ghez, Caer McCabe
We summarize here the observed properties of ``infrared companions'' to T Tauri stars and argue that their observational properties are identical to those of Class I sources. They…
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…
Low-mass binaries in the young cluster IC 348: implications for binary formation and evolution
Gaspard Duchene, Jerome Bouvier, Theodore Simon
We report on a near-infrared adaptive optics survey of a sample of 66 low-mass members of the pre-main sequence stellar cluster IC 348. We find 12 binary systems in the separation…
Binary fraction in low-mass star forming regions: a reexamination of the possible excesses and implications
Gaspard Duchene
Various surveys of low-mass binaries in star forming regions have been performed in recent years. They reached opposite conclusions concerning possible binary excesses in some of t…
