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…
The progenitors and circumstellar environments of stripped-envelope interacting supernovae from BPASS
B. Warwick, J. Lyman, D. L. Coppejans +4
Understanding the progenitors of stripped-envelope interacting supernovae (SEISNe) is crucial for probing the final stages of massive star evolution. Despite this, their rarity mea…
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…
First Light And Reionization Epoch Simulations (FLARES) XXI: The UV Indices of Galaxies in the Early Universe
Connor Sant Fournier, Stephen M. Wilkins, Joseph Caruana +5
UV absorption line indices trace chemical enrichment and star formation histories in high-redshift galaxies, yet their reliability as quantitative stellar metallicity, Z*, diagnost…
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…
Impact of Uncertainties in Spectral Energy Distribution Modelling on Inferred Galaxy Properties
Gareth T. Jones, Conor M. Byrne, Elizabeth R. Stanway
Interpreting galaxy properties from astronomical surveys relies heavily on spectral energy distribution (SED) modelling, yet uncertainties in key model ingredients are often overlo…
What do we mean by stellar mass? The impact of the pre-main sequence on the mass to light ratio of young and intermediate age stellar populations
Elizabeth R. Stanway, Conor M. Byrne, Ankur Upadhyaya
Stellar population synthesis models are an essential tool with which galaxy physical parameters are extracted from observations. However they are built on assumptions designed for…
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…
BPASS stellar evolution models incorporating -enhanced composition -- I. Single star models from 0.1 to 316 M
Conor M Byrne, Jan J Eldridge, Elizabeth R Stanway
Stellar evolution modelling is fundamental to many areas of astrophysics including stellar populations in both nearby and distant galaxies. It is heavily influenced by chemical com…
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…
First Light And Reionisation Epoch Simulations (FLARES) XIII: The Lyman-continuum emission of high-redshift galaxies
Louise T. C. Seeyave, Stephen M. Wilkins, Jussi K. Kuusisto +10
The history of reionisation is highly dependent on the ionising properties of high-redshift galaxies. It is therefore important to have a solid understanding of how the ionising pr…
On the impact of spectral template uncertainties in synthetic stellar populations
C. M. Byrne, E. R. Stanway
Uncertainties in stellar population models, both in terms of stellar evolution and stellar spectra, translate into uncertainties in our interpretation of stellar populations in gal…
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…
