Constraining Roche-Lobe Overflow Models Using the Hot-Subdwarf Wide Binary Population
Joris Vos, Maja Vučković
One of the important issues regarding the final evolution of stars is the impact of binarity. A rich zoo of peculiar, evolved objects are born from the interaction between the loos…
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…
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…
Testing eccentricity pumping mechanisms to model eccentric long period sdB binaries with MESA
Joris Vos, Roy Østensen, Pablo Marchant +1
Hot subdwarf-B stars in long-period binaries are found to be on eccentric orbits, even though current binary-evolution theory predicts those objects to be circularised before the o…
The orbits of subdwarf B + main-sequence binaries. I: The sdB+G0 system PG 1104+243
J. Vos, R. H. Östensen, P. Degroote +18
The predicted orbital period histogram of an sdB population is bimodal with a peak at short (< 10 days) and long (> 250 days) periods. Observationally, there are many short-period…
