Abstract (from CDS):

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 framework of the 'Magnetic Protostars and Planets' (MaPP) programme, and obtained at two different epochs (2009 July and 2011 June). From these observations, we first infer that GQ Lup has a photospheric temperature of 4300 ± 50 K and a rotation period of 8.4 ± 0.3 d; it implies that it is a 1.05 ± 0.07 M☉ star viewed at an inclination of ~=30°, with an age of 2-5 Myr and a radius of 1.7 ± 0.2 R☉, and has just started to develop a radiative core.
