An extremely peculiar hot subdwarf with a ten-thousand-fold excess of zirconium, yttrium, and strontium
Naslim N., C. S. Jeffery, N. T. Behara +1
Helium-rich subdwarf B (He-sdB) stars represent a small group of low-mass hot stars with luminosities greater than those of conventional subdwarf B stars, and effective temperature…
Abundance analyses of helium-rich subluminous B stars
N. Naslim, C. S. Jeffery, A. Ahmad +2
The connection between helium-rich hot subdwarfs of spectral types O and B (He-sdB) has been relatively unexplored since the latter were found in significant numbers in the 1980's.…
The gravitational wave signal from diverse populations of double white dwarf binaries in the Galaxy
Shenghua Yu, C. Simon Jeffery
Using a detailed Galactic model in which we consider distinct contributions from the bulge, thin disc, thick disc, and halo, and a population synthesis approach, we determined the…
Multi-wavelength observations of the helium dwarf nova KL Dra through its outburst cycle
Gavin Ramsay, Iwona Kotko, Tom Barclay +6
We present multi-wavelength observations of the helium-dominated accreting binary KL Dra which has an orbital period of 25 mins. Our ground-based optical monitoring programme using…
Stellar Winds and Mass Loss from Extreme Helium Stars
C. S. Jeffery W. -R. Hamann
Extreme helium stars are very rare low-mass supergiants in a late stage of evolution. They are probably contracting to become white dwarfs following a violent phase of evolution wh…
