Abstract: |
HD 4539 is a bright subdwarf-B (sdB) star not known to be variable
photometrically, but showing line profile variations which may be
interpreted as g-mode pulsation. In the present paper, I report
photometry obtained as part of a search for evidence of HD 4539 being
a photometric variable. While the photometric time-series obtained
and the radial velocity time-series from the literature were found to
have a frequency in common at 9.28 cycles/day, a meticulous
examination of errors is needed to confirm the photometric variability
of HD 4539. |
