Eclipsing binaries in open clusters
J. Southworth, P. F. L. Maxted, B. Smalley
Accurate physical parameters have been determined for two early-type detached eclipsing binaries in the open cluster h Persei (NGC 869). Masses accurate to 1.5% are derived from hi…
On the magnetic accretor GK Persei in outburst
Coel Hellier, Sean Harmer, A. P. Beardmore
RXTE made 5 X-ray observations of the magnetic accretor GK Per during its 1996 outburst, recording a count rate of ten times the quiescent level. The 351-s spin pulse shows a deep,…
Twisted accretion curtains in the intermediate polar FO Aquarii
P. A. Evans, Coel Hellier, Gavin Ramsay +1
We report on a ~37-ks XMM-Newton observation of the intermediate polar FO Aquarii, presenting X-ray and UV data from the EPIC and OM cameras. We find that the system has changed fr…
Eclipsing binaries in open clusters. I. V615 Per and V618 Per in h Per
J. Southworth, P. F. L. Maxted, B. Smalley
We derive absolute dimensions for two early-type main sequence detached eclipsing binaries in the young open cluster h Persei (NGC 869). V615 Persei has a spectral type of B7V and…
Magnetic topology and surface differential rotation on the K1 subgiant of the RS CVn system HR 1099
P. Petit, J. -F. Donati, G. A. Wade +8
We present here spectropolarimetric observations of the RS CVn system HR 1099 (V711 Tau) secured from 1998 February to 2002 January with the spectropolarimeter MuSiCoS at the Teles…
Spectroscopy of the Optical Counterpart to Ser X-1
R. I. Hynes, P. A. Charles, L. van Zyl +4
We present WHT and VLT spectroscopy of MM Ser, the optical counterpart to Ser X-1. We deblend the red spectra of the two close stars identified by Wachter (1997) and show that the…
