Discovery of a Long-Period Photometric Variation in the V361 Hya Star HS 0702+6043
S. Schuh, J. Huber, E. M. Green +4
We report the discovery of a long-period g-mode oscillation in the previously known short-period p-mode sdB pulsator HS 0702+6043. This makes this star an extraordinary object, uni…

Discovery of magnetic fields in CPNs
S. Jordan, K. Werner, S. J. O'Toole
For the first time we have directly detected magnetic fields in central stars of planetary nebulae by means of spectro-polarimetry with FORS1 at the VLT. In all four objects of our…

Discovery of magnetic fields in hot subdwarfs
S. J. O'Toole, S. Jordan, S. Friedrich +1
We present initial results of a project to measure mean longitudinal magnetic fields in a group of sdB/OB/O stars. The project was inspired by the discovery of three super-metal-ri…
