The Rossiter-McLaughlin effect of CoRoT-3b & HD189733b (2009)
Queloz, Didier, Bouchy, Francois, Moutou, Claire, Cameron, Andrew Collier, Claret, Antonio, ...
We present radial-velocity sequences acquired during three transits of the exoplanet HD 189733b and one transit of the CoRoT-3b. We applied a combined Markov-Chain Monte Carlo analysis of...
Reflected light from 3D exoplanetary atmospheres and simulation of HD 209458b (2008)
Hood, Ben, Wood, Kenneth, Seager, Sara, Cameron, Andrew Collier
We present radiation transfer models that demonstrate that reflected light levels from three dimensional (3D) exoplanetary atmospheres can be more than 50% lower than those predicted by models of...
The On/Off Nature of Star-Planet Interactions (2007)
Shkolnik, Evgenya, Bohlender, David A., Walker, Gordon A. H., Cameron, Andrew Collier
Evidence suggesting an observable magnetic interaction between a star and its hot Jupiter appears as a cyclic variation of stellar activity synchronized to the planet's orbit. In this study, we...
The Large-Scale Axisymmetric Magnetic Topology of a Very-Low-Mass Fully Convective Star (2007)
Donati, Jean-François, Forveille, Thierry, Cameron, Andrew Collier, Barnes, John R., Delfosse, Xavier, Jardine, Moira M., ...
Understanding how cool stars produce magnetic fields within their interiors is crucial for predicting the impact of such fields, such as the activity cycle of the Sun. In this respect, studying fully...
Kane, Stephen R., Cameron, Andrew Collier, Horne, Keith, James, David, Lister, T. A., Pollacco, Don L., ...
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 monitoring program which...
Kane, Stephen R., Lister, T. A., Cameron, Andrew Collier, Horne, Keith, James, David, Pollacco, Don L., ...
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 variable stars...
A dearth of planetary transits in the direction of NGC 6940 (2005)
Hood, Ben, Cameron, Andrew Collier, Kane, Stephen R., Bramich, D. M., Horne, Keith, Street, Rachel A., ...
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 millimags at the...
Kane, Stephen R., Cameron, Andrew Collier, Horne, Keith, James, David, Lister, Tim A., Pollacco, Don L., ...
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 their parent star....
Using Chandra/LETG spectra to probe stellar coronae (2004)
Hussain, Gaitee A. J., Brickhouse, Nancy, Dupree, Andrea K., Van Ballegooijen, Adriaan A., Cameron, Andrew Collier, Jardine, Moira, ...
We probe the relationship between surface magnetic fields and the X-ray emitting corona in the rapidly rotating star AB Dor. Circularly polarised spectra have been inverted to produce a surface...
Recent Results from the Wide Angle Search for Planets (WASP) Prototype (2002)
Kane, Stephen R., Horne, Keith, Street, Rachel A., Pollacco, Don L., James, David, Tsapras, Yiannis, ...
WASP0 is a prototype for what is intended to become a collection of WASPs whose primary aim is to detect transiting extra-solar planets across the face of their parent star. The WASP0 instrument is a...
tau Boo b: Not so bright, but just as heavy (2000)
Cameron, Andrew Collier, Horne, Keith, James, David, Penny, Alan, Semel, Meir
We present new results derived from high-resolution optical spectra of the tau Boo system, secured in March-May 2000. The results do not show the same feature reported by Cameron et al (1999) as a...
X-ray Emission From Nearby M-dwarfs: the Super-saturation Phenomenon (2000)
James, David J, Jardine, Moira M, Jeffries, Robin D, Randich, Sofia, Cameron, Andrew Collier, Ferreira, Miguel
A rotation rate and X-ray luminosity analysis is presented for rapidly rotating single and binary M-dwarf systems. X-ray luminosities for the majority of both single & binary M-dwarf systems with...
Probable detection of starlight reflected from the giant exoplanet orbiting tau Bootis (1999)
Cameron, Andrew Collier, Horne, Keith, Penny, Alan, James, David
Giant planets orbiting stars other than the Sun are clearly detectable through precise radial-velocity measurements of the orbital reflex motion of the parent star. In the four years since the...
New Distance Measurements to the $\alpha$ Persei and Pleiades Clusters (1993)
O'Dell, Mark A., Hendry, Martin A., Cameron, Andrew Collier
We apply the new distance measuring technique of Hendry, O'Dell and Collier- Cameron, 1993, to the Pleiades and $\alpha$ Persei clusters. The method relies on knowledge of the periods, rotation...
