The Monitor project: Rotation periods of low-mass stars in M50 (2008)
Irwin, Jonathan, Aigrain, Suzanne, Bouvier, Jerome, Hebb, Leslie, Hodgkin, Simon, Irwin, Mike, ...
We report on the results of a time-series photometric survey of M50 (NGC 2323), a ~130 Myr open cluster, carried out using the CTIO 4m Blanco telescope and Mosaic-II detector as part of the Monitor...
Star-Planet Interactions (2008)
Shkolnik, Evgenya, Aigrain, Suzanne, Cranmer, Steven, Fares, Rim, Fridlund, Malcolm, Pont, Frederic, ...
Much effort has been invested in recent years, both observationally and theoretically, to understand the interacting processes taking place in planetary systems consisting of a hot Jupiter orbiting...
The Monitor project: the search for transits in the open cluster NGC 2362 (2008)
Miller, Adam A., Irwin, Jonathan, Aigrain, Suzanne, Hodgkin, Simon, Hebb, Leslie
We present the results of a systematic search for transiting planets in a ~5 Myr open cluster, NGC 2362. We observed ~1200 candidate cluster members, of which ~475 are believed to be genuine cluster...
Reconstruction of the transit signal in the presence of stellar variability (2008)
Alapini, Aude, Aigrain, Suzanne
Intrinsic stellar variability can hinder the detection of shallow transits, particularly in space-based data. Therefore, this variability has to be filtered out before running the transit search....
Irwin, Jonathan, Hodgkin, Simon, Aigrain, Suzanne, Bouvier, Jerome, Hebb, Leslie, Irwin, Mike, ...
We report on the results of a time-series photometric survey of NGC 2362, carried out using the CTIO 4m Blanco telescope and Mosaic-II detector as part of the Monitor project. Rotation periods were...
The Monitor project: tracking the evolution of low mass and pre-main sequence stars (2007)
Aigrain, Suzanne, Irwin, Jonathan, Hebb, Leslie, Hodgkin, Simon, Miller, Adam, Moraux, Estelle, ...
The Monitor project is a large-scale program of photometric and spectroscopic monitoring of young open clusters using telescopes at ESO and other observatories. Its primary goal is to detect and...
The Monitor project: Rotation of low-mass stars in the open cluster NGC 2547 (2007)
Irwin, Jonathan, Hodgkin, Simon, Aigrain, Suzanne, Bouvier, Jerome, Hebb, Leslie, Moraux, Estelle
We report on the results of an I-band time-series photometric survey of NGC 2547 using the MPG/ESO 2.2m telescope with WFI, achieving better than 1% photometric precision per data point over 14
Irwin, Jonathan, Aigrain, Suzanne, Hodgkin, Simon, Stassun, Keivan G., Hebb, Leslie, Irwin, Mike, ...
We report the discovery of a low-mass (0.26 +/- 0.02, 0.15 +/- 0.01 Msol) pre-main-sequence eclipsing binary with a 5.3 day orbital period. JW 380 was detected as part of a high-cadence time-resolved...
Aigrain, Suzanne, Pont, Frederic
We present an extension of the formalism recently proposed by Pepper & Gaudi to evaluate the yield of transit surveys in homogeneous stellar systems, incorporating the impact of correlated noise on...
The Monitor project: Rotation of low-mass stars in the open cluster NGC 2516 (2007)
Irwin, Jonathan, Hodgkin, Simon, Aigrain, Suzanne, Hebb, Leslie, Bouvier, Jerome, Clarke, Cathie, ...
We report on the results of an i-band time-series photometric survey of NGC 2516 using the CTIO 4m Blanco telescope and 8k Mosaic-II detector, achieving better than 1% photometric precision per data...
The Monitor project: Data processing and lightcurve production (2006)
Irwin, Jonathan, Irwin, Mike, Aigrain, Suzanne, Hodgkin, Simon, Hebb, Leslie, Moraux, Estelle
We have begun a large-scale photometric survey of nearby open clusters and star-forming regions, the Monitor project, aiming to measure time-series photometry for >10,000 cluster members over >10...
The Monitor project: Searching for occultations in young open clusters (2006)
Aigrain, Suzanne, Hodgkin, Simon, Irwin, Jonathan, Hebb, Leslie, Irwin, Mike, Favata, Fabio, ...
The Monitor project is a photometric monitoring survey of nine young (1-200Myr) clusters in the solar neighbourhood to search for eclipses by very low mass stars and brown dwarfs and for planetary...
The Monitor project: Rotation of low-mass stars in the open cluster M34 (2006)
Irwin, Jonathan, Aigrain, Suzanne, Hodgkin, Simon, Irwin, Mike, Bouvier, Jerome, Clarke, Cathie, ...
We report on the results of a V and i-band time-series photometric survey of M34 (NGC 1039) using the Wide Field Camera (WFC) on the Isaac Newton Telescope (INT), achieving better than 1% precision...
Planetary transits and stellar variability (2005)
This thesis focuses on the detection of extrasolar planets via the transit method, and more specifically addresses issues relevant to the preparation of upcoming space missions such as CoRoT, Kepler,...
