Abstract:
We present results of our spectroscopic observations of nine detached
eclipsing binaries (DEBs), selected from the Kepler Eclipsing Binary
Catalog, that only show one set of spectral lines. Radial velocities
(RVs) were calculated from the high-resolution spectra obtained with
the HIgh-Dispersion Echelle Spectrograph (HIDES) instrument, attached
to the 1.88-m telescope at the Okayama Astrophysical Observatory, and
from the public Apache Point Observatory Galactic Evolution Experiment
archive. In our sample, we found five single-lined binaries, with one
component dominating the spectrum. The orbital and light-curve
solutions were found for four of them, and compared with isochrones,
in order to estimate absolute physical parameters and evolutionary
status of the components. For the fifth case, we only update the
orbital parameters, and estimate the properties of the unseen star.
Two other systems show orbital motion with a period known from the
eclipse timing variations (ETVs). For these we obtained parameters of
outer orbits, by translating the ETVs to RVs of the centre of mass of
the eclipsing binary, and combining with the RVs of the outer star. Of
the two remaining ones, one is most likely a blend of a faint
background DEB with a bright foreground star, which lines we see in
the spectra, and the last case is possibly a quadruple bearing a
sub-stellar mass object. Where possible, we compare our results with
literature, especially with results from asteroseismology. We also
report possible detections of solar-like oscillations in our RVs.
Description:
Targets were selected from the Kepler Eclipsing Binaries Catalog
(KEBC; Prsa et al. 2011, Cat. J/AJ/141/83; Slawson et al. 2011, Cat.
J/AJ/142/160; Kirk et al. 2016, Cat. J/AJ/151/68)
(http://keplerebs.villanova.edu/)
The spectroscopic observations were carried out at the 1.88-m
telescope of the Okayama Astrophysical Observatory (OAO) with the
HIgh-Dispersion Echelle Spectrograph (HIDES, R∼50000).
The observations were made between 2014 July and 2016 June.
