Surface brightness inhomogeneity on the helium-rich hot subdwarf in the X-ray binary HD 49798
C. Simon Jeffery, Gavin Ramsay
HD 49798 is an X-ray binary consisting of a hot helium-rich subdwarf primary and an accreting compact companion with an orbital period of 1.55 d. TESS observations of its optical l…
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…
Spectroscopic diagnostics of lead stratification in hot subdwarf atmospheres
L. J. A. Scott, C. S. Jeffery, C. M. Byrne +1
Heavy metal subdwarfs are a class of hot subdwarfs with very high abundances of heavy elements, typically around 10 000 times solar. They include stars which are strongly enhanced…
