High-speed spectroscopy of two pulsating subdwarf B stars, KPD 210914401 and PB 8783, is presented. Radial motions are detected with the same frequencies as reported from photometric observations and with amplitudes of ,2 km s in two or more independent modes. These represent the first direct observations of surface motion arising from multimode non-radial… CONTINUE READING
