The gravitational-wave signal generated by a galactic population of double neutron-star binaries
Shenghua Yu, C. Simon Jeffery
We investigate the gravitational wave (GW) signal generated by a population of double neutron-star binaries (DNS) with eccentric orbits caused by kicks during supernova collapse an…
Subaru and Swift observations of V652 Herculis: resolving the photospheric pulsation
C. S. Jeffery, D. Kurtz, H. Shibahashi +4
High resolution spectroscopy with the Subaru High Dispersion Spectrograph, and Swift ultraviolet photometry are presented for the pulsating extreme helium star V652\,Her. Swift pro…
Radial velocity measurements of the pulsating zirconium star: LS IV -14 116
C. Simon Jeffery, Amir Ahmad, Naslim Neelamkodan +1
The helium-rich hot subdwarf LS IV -14 116 shows remarkably high surface abundances of zirconium, yttrium, strontium, and germanium, indicative of strong chemical stratification in…
White paper: Gaia and the end states of stellar evolution
M. A Barstow, S. L. Casewell, S. Catalan +18
This is the product of a Gaia GREAT workshop on "Gaia and the end states of stellar evolution" held at the University of Leicester in April 2011.
KIC 1718290: A Helium-rich V1093-Her-like Pulsator on the Blue Horizontal Branch
Roy H. Østensen, Pieter Degroote, John H. Telting +6
We introduce the first g-mode pulsator found to reside on the classical blue horizontal branch. One year of Kepler observations of KIC 1718290 reveals a rich spectrum of low-amplit…
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.…
