Magnetometry of the classical T Tauri star GQ Lup: non-stationary dynamos & spin evolution of young Suns
J. F. Donati, S. G. Gregory, S. H. P. Alencar +7
We report here results of spectropolarimetric observations of the classical T Tauri star (cTTS) GQ Lup carried out with ESPaDOnS at the Canada-France-Hawaii Telescope (CFHT) in the…
Accretion dynamics in the classical T Tauri star V2129 Oph
S. H. P. Alencar, J. Bouvier, F. M. Walter +9
We analyze the photometric and spectroscopic variability of the classical T Tauri star V2129 Oph over several rotational cycles to test the dynamical predictions of magnetospheric…
The Gemini NICI Planet-Finding Campaign: Discovery of a Multiple System Orbiting the Young A Star HD 1160
Eric L. Nielsen, Michael C. Liu, Zahed Wahhaj +22
We report the discovery by the Gemini NICI Planet-Finding Campaign of two low-mass companions to the young A0V star HD 1160 at projected separations of 81 +/- 5 AU (HD 1160 B) and…
