Magnetic fields and accretion flows on the classical T Tauri star V2129 Oph
JF Donati, MM Jardine, SG Gregory +8
From observations collected with the ESPaDOnS spectropolarimeter, we report the discovery of magnetic fields at the surface of the mildly accreting classical T Tauri star V2129 Oph…
The coronal structure of AB Dor determined from contemporaneous Doppler imaging and X-ray spectroscopy
G. A. J. Hussain, M. Jardine, J. -F. Donati +6
We obtain contemporaneous observations of the surface and corona of AB Dor using ground-based circularly polarised spectra from the Anglo-Australian Telescope and X-ray data from t…
Rotational Modulation of X-ray Emission from T Tauri Stars
S. G. Gregory, M. Jardine, A. Collier Cameron +1
We have modeled the rotational modulation of X-ray emission from T Tauri stars assuming that they have isothermal, magnetically confined coronae. By extrapolating surface magnetogr…
Inferring coronal structure using X-ray spectra: A Chandra study of AB Dor
G. A. J. Hussain, N. S. Brickhouse, A. K. Dupree +5
The Chandra X-ray observatory monitored the single cool star, AB Doradus, continuously for a period lasting 88ksec (1.98 Prot) in 2002 December with the LETG/HRC-S. The X-ray light…
