Abstract: |
We present preliminary results from an ongoing spectroscopic survey
for binarity in a sample of 15 pulsating and a few non-pulsating sdB
stars observed with the Kepler spacecraft. We used the INT, NOT,
KP4m, and WHT telescopes to obtain low-resolution spectroscopy of our
sample stars, and applied a standard cross-correlation technique to derive
radial-velocities. We find clear evidence for binarity in several of
the pulsators, some of which were not previously known to be binaries. |
