The close classical T Tauri binary V4046 Sgr: Complex magnetic fields & distributed mass accretion
J. F. Donati, S. G. Gregory, T. Montmerle +12
We report here the first results of a multi-wavelength campaign focussing on magnetospheric accretion processes within the close binary system V4046 Sgr, hosting two partly-convect…
The large-scale magnetic field and poleward mass accretion of the classical T Tauri star TW Hya
JF Donati, SG Gregory, SHP Alencar +9
We report here results of spectropolarimetric observations of the ~8Myr classical TTauri star (cTTS) TWHya carried out with ESPaDOnS at the Canada-France-Hawaii Telescope (CFHT) in…
The Photoevaporative Wind from the Disk of TW Hya
I. Pascucci, M. Sterzik, R. D. Alexander +6
Photoevaporation driven by the central star is expected to be a ubiquitous and important mechanism to disperse the circumstellar dust and gas from which planets form. Here, we pres…
The Gemini NICI Planet-Finding Campaign : Discovery of a Substellar L Dwarf Companion to the Nearby Young M Dwarf CD-35 2722
Zahed Wahhaj, Michael C. Liu, Beth A. Biller +23
We present the discovery of a wide (67 AU) substellar companion to the nearby (21 pc) young solar-metallicity M1 dwarf CD-35 2722, a member of the ~100 Myr AB Doradus association.…
