The search for roAp stars: null results and new candidates from Stroemgren-Crawford photometry
E. Paunzen, G. Handler, K. Honkova +10
The rapidly oscillating Ap (roAp) stars exhibit pulsational photometric and/or radial velocity variations on time scales of several minutes, which are essential to test current pul…
