The Monitor project: Rotation periods of low-mass stars in M50
Jonathan Irwin, Suzanne Aigrain, Jerome Bouvier +4
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 pa…
High Spatial Resolution Galactic 3D Extinction Mapping with IPHAS
S. E. Sale, J. E. Drew, Y. C. Unruh +12
We present an algorithm ({\scshape mead}, for `Mapping Extinction Against Distance') which will determine intrinsic () colour, extinction, and distance for early-A to K4 s…
A planetary nebula around nova V458 Vul undergoing flash ionization
R. Wesson, M. J. Barlow, R. L. M. Corradi +25
Nova V458 Vul erupted on 2007 August 8th and reached a visual magnitude of 8.1 a few days later. H images obtained six weeks before the outburst as part of the IPHAS galactic pl…
The AAT/WFI survey of the Monoceros Ring and Canis Major Dwarf galaxy: II. from l = (280 - 025)deg
Blair C. Conn, Richard R. Lane, Geraint F. Lewis +5
This paper concludes a systematic search for evidence of the Monoceros Ring and Canis Major dwarf galaxy around the Galactic Plane. Presented here are the results for the Galactic…
The kinematic footprints of five stellar streams in Andromeda's halo
S. C. Chapman, R. Ibata, M. Irwin +12
(abridged) We present a spectroscopic analysis of five stellar streams (`A', `B', `Cr', `Cp' and `D') as well as the extended star cluster, EC4, which lies within streamC, all disc…
The nucleus of the Sagittarius dSph galaxy and M54: a window on the process of galaxy nucleation
M. Bellazzini, R. A. Ibata, S. C. Chapman +6
We present the results of a thorough study of the nucleus of the Sgr dwarf spheroidal galaxy and of the bright globular cluster M54 that resides within the same nucleus (Sgr,N). We…
