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...
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...

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...
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...
The luminosity function of the Virgo Cluster from M_B=-22 to M_B=-11 (2002)
Trentham, Neil, Hodgkin, Simon
We measure the galaxy luminosity function (LF) for the Virgo Cluster between blue magnitudes M_B = -22 and M_B = -11 from wide-field CCD imaging data. The LF is only gradually rising for -22 < M_B <...
