Four Faint T Dwarfs from the UKIRT Infrared Deep Sky Survey (UKIDSS) Southern Stripe
Kuenley Chiu, Michael C. Liu, Linhua Jiang +6
We present the optical and near-infrared photometry and spectroscopy of four faint T dwarfs newly discovered from the UKIDSS first data release. The sample, drawn from an imaged ar…
Why are there so few hot Jupiters?
W. K. M. Rice, P. J. Armitage, D. F. Hogg
We use numerical simulations to model the migration of massive planets at small radii and compare the results with the known properties of 'hot Jupiters' (extrasolar planets with s…
Initial Data Release from the INT Photometric H-alpha Survey of the Northern Galactic Plane (IPHAS)
E. A. Gonzalez-Solares, N. A. Walton, R. Greimel +47
The INT/WFC Photometric H-alpha Survey of the Northern Galactic Plane (IPHAS) is an imaging survey being carried out in H-alpha, r' and i' filters, with the Wide Field Camera (WFC)…
The Monitor project: Rotation of low-mass stars in NGC 2362 -- testing the disc regulation paradigm at 5 Myr
Jonathan Irwin, Simon Hodgkin, Suzanne Aigrain +4
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. Rota…
A Population of Faint Extended Line Emitters and the Host Galaxies of Optically Thick QSO Absorption Systems
Michael Rauch, Martin Haehnelt, Andrew Bunker +10
We have conducted a long slit search for low surface brightness Lyman-alpha emitters at redshift 2.67 < z < 3.75. A 92 hour long exposure with VLT/FORS2 down to a 1-sigma surface b…
The Monitor project: Rotation of low-mass stars in the open cluster NGC 2547
Jonathan Irwin, Simon Hodgkin, Suzanne Aigrain +3
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…
