Current Status of the SuperWASP Project
D. J. Christian, D. L. Pollacco, W. I. Clarkson +16
We present the current status of the SuperWASP project, a Wide Angle Search for Planets. SuperWASP consists of up to 8 individual cameras using ultra-wide field lenses backed by hi…
LO Peg in 1998: Starspot patterns and differential rotation
J. R. Barnes, A. Collier Cameron, T. A. Lister +2
We present Doppler images of the young K5V - K7V rapid rotator LO Peg from seven nights of continuous spectroscopy obtained in 1998 from July 04 to July 10. The images reveal the p…
The Dependence of Differential Rotation on Temperature and Rotation
J. R. Barnes, A. Collier Cameron, J. -F. Donati +3
We use Doppler imaging techniques to determine the dependence of starspot rotation rates on latitude in an homogeneous sample of young, rapidly-rotating solar analogues. A solar-li…
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…
A Prototype for the PASS Permanent All Sky Survey
H. J. Deeg, R. Alonso, J. A. Belmonte +4
A prototype system for the Permanent All Sky Survey (PASS) project is presented. PASS is a continuous photometric survey of the entire celestial sphere with a high temporal resolut…
Results from the Wide Angle Search for Planets Prototype (WASP0) I: Analysis of the Pegasus Field
Stephen R. Kane, Andrew Collier Cameron, Keith Horne +5
WASP0 is a prototype for what is intended to become a collection of wide-angle survey instruments whose primary aim is to detect extra-solar planets transiting across the face of t…
Dynamics of the circumstellar gas in the Herbig Ae stars BF Orionis, SV Cephei, WW Vulpeculae and XY Persei
A. Mora, C. Eiroa, A. Natta +22
We present high resolution (lambda / Delta_lambda = 49000) echelle spectra of the intermediate mass, pre-main sequence stars BF Ori, SV Cep, WW Wul and XY Per. The spectra cover th…
Differential rotation of cool active stars
P. Petit, J. -F. Donati, A. Collier Cameron
The surface differential rotation of active solar-type stars can be investigated by means of Doppler and Zeeman-Doppler Imaging, both techniques enabling one to estimate the short-…
Multi-Site observations of SU Aurigae
Y. C. Unruh, J. -F. Donati, J. M. Oliveira +20
We present results from the 1996 MUSICOS (MUlti-SIte COntinuous Spectroscopy) campaign on the T Tauri star SU Aurigae. We find a 2.7-d periodicity in the He I (587.6 nm) line and s…
