The coronal structure of Speedy Mic - I: A densely packed prominence system beyond co-rotation
N. J. Dunstone, J. R. Barnes, A. Collier Cameron +1
We present new observations of the prominence system on the K3 dwarf Speedy Mic (BO Mic, HD 197890). Using an improved technique to track the absorption features in H_alpha we find…
Results from the Wide Angle Search for Planets Prototype (WASP0) III: Planet Hunting in the Draco Field
Stephen R. Kane, Andrew Collier Cameron, Keith Horne +5
The Wide Angle Search for Planets prototype (WASP0) is a wide-field instrument used to search for extra-solar planets via the transit method. Here we present the results of a monit…
Results from the Wide Angle Search for Planets Prototype (WASP0) II: Stellar Variability in the Pegasus Field
Stephen R. Kane, T. A. Lister, Andrew Collier Cameron +5
Recent wide-field photometric surveys which target a specific field for long durations are ideal for studying both long and short period stellar variability. Here we report on 75 v…
A dearth of planetary transits in the direction of NGC 6940
Ben Hood, Andrew Collier Cameron, Stephen R. Kane +10
We present results of our survey for planetary transits in the field of NGC 6940. We think nearly all of our observed stars are field stars. We have obtained high precision (3-10 m…
A Survey for Planetary Transits in the Field of NGC 7789
D. M. Bramich, Keith Horne, I. A. Bond +12
We present results from 30 nights of observations of the open cluster NGC 7789 with the WFC camera on the INT telescope in La Palma. From ~900 epochs, we obtained lightcurves and S…
Direct Evidence for a Polar Spot on SV Cam
S. V. Jeffers, A. Collier Cameron, J. R. Barnes +2
We have used spectrophotometric data from the Hubble Space Telescope to eclipse-map the primary component of the RS CVn binary SV Cam over 9 HST orbits. We find from these observat…
