Accuracy of stellar parameters of exoplanet-host stars determined from asteroseismology
(EDP Sciences, 2009)Context. In the context of the space-based mission CoRoT, devoted to asteroseismology and search for planet transits, we analyse the accuracy of fundamental stellar parameters (mass, radius, luminosity) that can be obtained ... -
Bayesian detection of planetary transits. A modified version of the Gregory-Loredo method for Bayesian periodic signal detection
(EDP Sciences, 2002)The detection of planetary transits in stellar photometric light-curves is poised to become the main method for finding substantial numbers of terrestrial planets. The French-European mission COROT (foreseen for launch in ... -
Can non-ideal magnetohydrodynamics solve the magnetic braking catastrophe? (Dataset)
(University of Exeter, 2015-12-31)We investigate whether or not the low ionization fractions in molecular cloud cores can solve the ‘magnetic braking catastrophe’, where magnetic fields prevent the formation of circumstellar discs around young stars. We ... -
Characterising stellar micro-variability for planetary transit searches
(EDP Sciences, 2004)A method for simulating light curves containing stellar micro-variability for a range of spectral types and ages is presented. It is based on parameter-by-parameter scaling of a multi-component fit to the solar irradiance ... -
Collapse of a molecular cloud core to stellar densities: stellar core and outflow formation in radiation magnetohydrodynamics simulations (Dataset)
(University of Exeter (Data), 2013-10-10)This is the dataset that was used to produce the paper published in MNRAS. It contains the output from each of the SPH simulations, including dump files and the scripts used to generate the figures for the paper. To view ... -
Combining radiative transfer and diffuse interstellar medium physics to model star formation (Dataset)
(University of Exeter (dataset) / Oxford University Press (paper), 2015-04-23)This is the dataset that was used to produce the associated paper, published in MNRAS. It contains the output from each of the SPH simulations, including dump files and the scripts used to generate the figures for the ... -
Comparative blind test of five planetary transit detection algorithms on realistic synthetic light curves
(EDP Sciences, 2005)Because photometric surveys of exoplanet transits are very promising sources of future discoveries, many algorithms are being developed to detect transit signals in stellar light curves. This paper compares such algorithms ... -

Detecting planetary transits in the presence of stellar variability. Optimal filtering and the use of colour information
(EDP Sciences, 2003)Space-based photometric transit searches, such as the ESA mission Eddington (planned for launch in 2007), are expected to detect large numbers of terrestrial planets outside the solar system, including some Earth-like ... -

Ground-based photometry of space-based transit detections: photometric follow-up of the CoRoT mission
(EDP Sciences, 2009)The motivation, techniques and performance of the ground-based photometric follow-up of transit detections by the CoRoT space mission are presented. Its principal raison d'être arises from the much higher spatial resolution ... -
