Evolutionary Constraints on the Long-period Subdwarf B Binary PG 1018-047
J. Deca, J. Vos, P. Németh +4
We have revisited the sdB+K-star long-period binary PG 1018-047 based on 20 new high-resolution VLT/UVES spectra that provided regular coverage over a period of more than 26 months…
Composite hot-subdwarf binaries -- I. The spectroscopically confirmed sdB sample
Joris Vos, Péter Németh, Maja Vučković +2
Hot subdwarf-B (sdB) stars in long-period binaries are found to be on eccentric orbits, even though current binary-evolution theory predicts these objects to be circularised before…
Radon Transforms over Lower-Dimensional Horospheres in Real Hyperbolic Space
W. O. Bray, B. Rubin
We study horospherical Radon transforms that integrate functions on the -dimensional real hyperbolic space over horospheres of arbitrary fixed dimension . Exact e…
The orbits of subdwarf-B + main-sequence binaries: III. The period - eccentricity distribution
Joris Vos, Roy H. Østensen, Maja Vuckovic +1
The predicted orbital-period distribution of the subdwarf-B (sdB) population is bi-modal with a peak at short (< 10 days) and long (> 500 days) periods. Observationally, many short…
Three new pulsating sdB stars discovered with SuperWASP
Daniel L. Holdsworth, Roy H. Østensen, Barry Smalley +1
We present an analysis of three new pulsating subdwarf B stars discovered in the SuperWASP archive. Two of the stars, J1938+5609 and J0902-0720, are p-mode pulsators; J1938+5609 sh…
