Are Superhumps Good Measures of the Mass Ratio for AM CVn Systems?

K. J. Pearson

We extend recent work that included the effect of pressure forces to derive the precession rate of eccentric accretion discs in cataclysmic variables to the case of double degenera…

Further Evidence for Variable Synchrotron Emission in XTE J1118+480 in Outburst

R. I. Hynes, E. L. Robinson, K. J. Pearson +7

We present simultaneous multicolor infrared and optical photometry of the black hole X-ray transient XTE J1118+480 during its short 2005 January outburst, supported by simultaneous…

Superhumps: Confronting Theory with Observation

K. J. Pearson

We review the theory and observations related to the ``superhump'' precession of eccentric accretion discs in close binary sytems. We agree with earlier work, although for differen…

Multiwavelength Observations of EXO 0748--676 -- II. Emission Line Behavior

K. J. Pearson, R. I. Hynes, D. Steeghs +6

We present optical and ultraviolet spectra, lightcurves, and Doppler tomograms of the low-mass X-ray binary EXO 0748-676. Using an extensive set of 15 emission line tomograms, we s…

A Survey for Planetary Transits in the Field of NGC 7789

D. M. Bramich, Keith Horne, I. A. Bond +12

We present results from 30 nights of observations of the open cluster NGC 7789 with the WFC camera on the INT telescope in La Palma. From ~900 epochs, we obtained lightcurves and S…

Fireballs, Flares and Flickering: A Semi-analytic, LTE, Explosive Model from Accretion Disks to Supernovae

K. J. Pearson, Keith Horne, Warren Skidmore

We derive simple analytic expressions for the continuum lightcurves and spectra of flaring and flickering events that occur over a wide range of astrophysical systems. We compare t…

Superhumps, Magnetic Fields and the Mass-ratio in AM Canum Venaticorum

K. J. Pearson

We show that the observed K-velocities and periodicities of AM CVn can be reconciled given a mass ratio of 0.22 and a secondary star with a modest magnetic field of surface strengt…

Fireballs, Flares and Flickering

K. J. Pearson, Keith Horne, Warren Skidmore

We review our understanding of the prototype ``Propeller'' system AE Aqr and we examine its flaring behaviour in detail. The flares are thought to arise from collisions between hig…

Fireball Models for Flares in AE Aquarii

K. J. Pearson, Keith Horne, Warren Skidmore

We examine the flaring behaviour of the cataclysmic variable AE~Aqr in the context of the `magnetic propeller' model for this system. The flares are thought to arise from collision…
