Abstract
The subdwarf B star PG1336-018 (=NY Vir) is a pulsating star in a very short-period (0.101 d) eclipsing binary system [4]. The secondary is thought to be a late-type dwarf of type ∼M5. The star pulsates with principal periods of 141 and 184 s and has been the subject of intensive photometric campaigns [5] in efforts to use pulsations as an asteroseismological probe of the stellar interior. As part of our efforts to identify the binary companions of subdwaf B stars spectroscopically [1], and to measure the radial-velocity amplitudes of the non-radial oscillations in pulsating subdwarf B stars [2], [7] we have obtained several observations of PG1336-018.
