The population of black widow pulsars
A. R. King, M. E. Beer, D. J. Rolfe +2
We consider the population of black widow pulsars (BWPs). The large majority of these are members of globular clusters. For minimum companion masses < 0.1 Msun, adiabatic evolution…
Multi-epoch Spectroscopy of IY UMa: Quiescence, Rise, Normal Outburst & Superoutburst
Daniel J. Rolfe, Carole A. Haswell, Timothy M. C. Abbott +3
We exploit rare observations covering the time before and during a normal outburst in the deeply-eclipsing SU UMa system IY UMa to study the dramatic changes in the accretion flow…
A New Evolutionary Channel for Type Ia Supernovae
A. R. King, D. J. Rolfe, K. Schenker
We show that long-period dwarf novae offer a promising route for making Type Ia supernovae. For typical dwarf nova duty cycles d ~ 0.1 - 0.01, mass is accreted by the white dwarf m…
The detection of the donor star in IY UMa
Daniel J. Rolfe, Timothy M. C. Abbott, Carole A. Haswell
We present the results of a search for the donor star in the high inclination SU UMa type cataclysmic variable IY UMa. We detect absorption features in the near infrared consistent…
Doppler Tomography of Dwarf Nova IY UMa during Quiescence
Daniel J. Rolfe, Timothy M. C. Abbott, Carole A. Haswell
Quiescent Doppler tomography of the newly discovered deeply-eclipsing SU UMa system IY UMa reveals properties of the region where the accretion stream from the donor impacts the ed…
Late superhumps and the stream-disc impact in IY UMa
Daniel J. Rolfe, Carole A. Haswell, Joseph Patterson
We use the hot spot eclipse times of the newly discovered deeply-eclipsing dwarf nova IY UMa to trace out the shape of its disc during the late superhump era. We find an eccentric…
