The diverse morphology of gravitational wave signals from merging neutron-star white-dwarf binaries
Shenghua Yu, Youjun Lu, C. Simon Jeffery +6
In sufficiently compact neutron star-white dwarf (NSWD) binary systems, orbital decay means the white dwarf eventually fills its shrinking Roche lobe, initiating a phase of mass tr…
Theoretical models for the Late Thermal Pulse in post-AGB stars: the case of DY Cen
Zhongyang Liu, C. Simon Jeffery, Xianfei Zhang +2
We present theoretical predictions of the born-again scenario for post-asymptotic giant-branch stars. An extensive model grid for born-again objects has been constructed, particula…
K2 observations of five pulsating subdwarf B stars with white dwarf companions
M. D. Reed, A. S. Baran, J. H. Telting +3
We report seismic analyses of five pulsating subdwarf B (sdBV) stars observed during Kepler's K2 mission, each with a white dwarf companion. We find three of the five to be g-mode-…
Linear and non-linear models for large-amplitude radial pulsation in faint blue stars (BLAPs)
C. S. Jeffery
The recent discovery of large-amplitude pulsations in faint blue stars (BLAPs) provides both challenges for stellar pulsation theory and opportunities to explore the late evolution…
