متن کاملRadial velocities of pulsating subdwarf B stars : KPD 2109 + 4401 and PB 8783 ⋆
High-speed spectroscopy of two pulsating subdwarf B stars, KPD2109+4401 and PB8783, is presented. Radial motions are detected with the same frequencies as reported from photometric observations and with amplitudes of ∼ 2 kms in two or more independent modes. These represent the first direct observations of surface motion due to multimode non-radial oscillations in subdwarf B stars. In the case ...
متن کاملRadial velocities of pulsating subdwarf B stars : KPD 2109 1 4401 and PB 8783
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 oscillations in subdwarf B stars. In t...
