Re-calibrated analytic stellar evolution formulae for the main sequence: Extension to massive stars and variations in
Conor M Byrne, Elizabeth R Stanway, Jan J Eldridge
Analytic formulae are an efficient way to approximate the evolution of a star of a given mass and chemical composition, and are widely used in the literature to compute large grids…
Direct detections of white dwarfs in four WD+dM post-common envelope binaries within 20 pc
Mairi W. O'Brien, David J. Wilson, Pier-Emmanuel Tremblay +5
Characterising post-common envelope binaries (PCEBs) containing a white dwarf and a main-sequence companion is essential for improving theories of binary evolution. This paper pres…
Helium-burning blue large-amplitude pulsators: A Population Study with BPASS
Zhengyang Zhang, Conor M. Byrne, Chengyuan Wu +1
Blue Large-Amplitude Pulsators (BLAPs) are a class of radially pulsating stars with effective temperatures ranging from 20,000 to 35,000 K and pulsation periods between 7 and 75 mi…
Comparison of methods used to derive the Galactic star formation history from white dwarf samples
Emily K. Roberts, Pier-Emmanuel Tremblay, Mairi W. O'Brien +4
We compare three methods of deriving the local Galactic star formation history, using as a benchmark the Gaia-defined 40 pc white dwarf sample, currently the largest volume complet…
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…
The Dependence of Theoretical Synthetic Spectra on -enhancement in Young, Binary Stellar Populations
C. M. Byrne, E. R. Stanway, J. J. Eldridge +2
The enhancement of elements such as oxygen is an important phase in the chemical evolution of the early Universe, with nebular material becoming enriched in these elements soon…
Binary evolution pathways of Blue Large-Amplitude Pulsators
C. M. Byrne, E. R. Stanway, J. J. Eldridge
Blue Large-Amplitude Pulsators (BLAPs) are a recently discovered class of pulsating star, believed to be proto-white dwarfs, produced by mass stripping of a red giant when it has a…
Pulsation in faint blue stars
Conor M. Byrne, C. Simon Jeffery
Following the discovery of blue large-amplitude pulsators (BLAPs) by the OGLE survey, additional hot, high-amplitude pulsating stars have been discovered by the Zwicky Transient Fa…
Post-common envelope binary stars: Radiative Levitation and Blue Large- Amplitude Pulsators
Conor Byrne, Simon Jeffery
Following the recent discovery of a new class of pulsating star, the blue large-amplitude pulsators (BLAPs), pulsation stability analysis was carried out on evolutionary models of…
Post-common-envelope binary stars, radiative levitation, and blue large-amplitude pulsators
Conor M. Byrne, C. Simon Jeffery
Following the discovery of blue large-amplitude pulsators (BLAPs), single star evolu- tion models of post red giant branch stars that have undergone a common envelope (CE) ejection…
The effects of diffusion in hot subdwarf progenitors from the common envelope channel
Conor M. Byrne, C. Simon Jeffery, Christopher A. Tout +1
Diffusion of elements in the atmosphere and envelope of a star can drastically alter its surface composition, leading to extreme chemical peculiarities. We consider the case of hot…
