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…
The component masses of the cataclysmic variable V347 Puppis
T. D. Thoroughgood, V. S. Dhillon, D. Steeghs +7
We present time-resolved spectroscopy and photometry of the double-lined eclipsing cataclysmic variable V347 Pup (= LB 1800). There is evidence of irradiation on the inner hemisphe…
SSSPM J1444-2019: an extremely high proper motion, ultracool subdwarf
R. -D. Scholz, N. Lodieu, M. J. McCaughrean
We present the discovery of a new extreme high proper motion object (3.5 arcsec/year) which we classify as an ultracool subdwarf with [M/H] = -0.5. It has a formal spectral type of…
H-alpha kinematics of a z ~ 1 disc galaxy from near-IR integral field spectroscopy
J. K. Smith, A. J. Bunker, N. P. Vogt +6
In this letter we present the first 3D spectroscopic study of H-alpha emission in a z ~ 1 field galaxy with an integral field unit. Using the CIRPASS spectrograph on Gemini-South w…
A new mass-ratio for the X-ray Binary X2127+119 in M15?
L. van Zyl, Z. Ioannou, P. A. Charles +1
The luminous low-mass X-ray binary X2127+119 in the core of the globular cluster M15 (NGC 7078), which has an orbital period of 17 hours, has long been assumed to contain a donor s…
The X-Ray Binary X2127+119 in M15: Evidence for a Very-Low-Mass, Stripped-Giant Companion
L. van Zyl, P. A. Charles, S. Arribas +3
We present integral field spectroscopy of X2127+119, the luminous X-ray binary in the globular cluster M15, obtained with INTEGRAL/WYFFOS on the William Herschel Telescope. We find…
