The X-ray source population of the globular cluster M15: Chandra high resolution imaging
D. C. Hannikainen, P. A. Charles, L. van Zyl +5
The globular cluster M15 was observed on three occasions with the High Resolution Camera on board Chandra in 2001 in order to investigate the X-ray source population in the cluster…
Rotational period of WD1953-011 - a magnetic white dwarf with a star spot
C. S. Brinkworth, T. R. Marsh, L. Morales-Rueda +3
WD1953-011 is an isolated, cool (7920 +/- 200K, Bergeron, Legget & Ruiz, 2001) magnetic white dwarf (MWD) with a low average field strength (~70kG, Maxted et al. 2000) and a higher…
Contamination and exclusion in the sigma Orionis young group
Ben Burningham, Tim Naylor, S. P. Littlefair +1
We present radial velocities for 38 low-mass candidate members of the sigma Orionis young group. We have measured their radial velocities by cross-correlation of high resolution (R…
The Lithium Depletion Boundary in NGC 2547 as a test of pre-main-sequence evolutionary models
R. D. Jeffries, J. M. Oliveira
Intermediate resolution spectroscopy from the ESO Very Large Telescope is analysed for 63 photometrically selected low-mass (0.08-0.30 Msun) candidates of the open cluster NGC 2547…
Pre-main-sequence Lithium Depletion
R. D. Jeffries
In this review I briefly discuss the theory of pre-main-sequence (PMS) Li depletion in low-mass (0.075<M<1.2 Msun) stars and highlight those uncertain parameters which lead to subs…
Subdwarf B Binaries from the Edinburgh--Cape Survey
L. Morales-Rueda, P. F. L. Maxted, T. R. Marsh +2
We present the first results of a campaign to obtain orbital solutions of subdwarf B (sdB) stars from the Edinburgh-Cape survey. We have obtained blue spectra of 35 sdBs, 20 of whi…
