Magnetic fields and differential rotation on the pre-main sequence III: The early-G star HD 106506
I. A. Waite, S. C. Marsden, B. D. Carter +5
We present photometry and spectropolarimetry of the pre-main sequence star HD 106506. A photometric rotational period of ~1.416 +/- 0.133 days has been derived using observations a…
Magnetic fields and differential rotation on the pre-main sequence II: The early-G star HD 141943 - coronal magnetic field, H-alpha emission and differential rotation
S. C. Marsden, M. M. Jardine, J. C. Ramírez Vélez +8
Spectropolarimetric observations of the pre-main sequence early-G star HD 141943 were obtained at three observing epochs (2007, 2009 and 2010). The observations were obtained using…
Magnetic fields and differential rotation on the pre-main sequence I: The early-G star HD 141943 - brightness and magnetic topologies
S. C. Marsden, M. M. Jardine, J. C. Ramírez Vélez +8
Spectroscopic and spectropolarimetric observations of the pre-main sequence early-G star HD 141943 were obtained at four observing epochs (in 2006, 2007, 2009 and 2010). The observ…
Surface magnetic fields on two accreting T Tauri stars: CV Cha and CR Cha
G. A. J. Hussain, A. Collier Cameron, M. M. Jardine +12
We have produced brightness and magnetic field maps of the surfaces of CV Cha and CR Cha: two actively accreting G and K-type T Tauri stars in the Chamaeleon I star-forming cloud w…
The Pre-Main-Sequence Eclipsing Binary ASAS J052821+0338.5
H. C. Stempels, L. Hebb, K. G. Stassun +4
In this paper we present the first results of a detailed spectroscopic and photometric analysis of the V = 11.7m eclipsing binary ASAS J052821+0338.5. With the FIES spectrograph at…
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…
