TY - JOUR ID - 1412238 AU - Paunzen, Ernst - Bernhard, Klaus - Hümmerich, Stefan PY - 2018 TI - Stellar activity and stellar pulsations in ground- and space-based observations JF - Contributions of the Astronomical Observatory Skalnaté Pleso VL - 48 IS - 1 SP - 66-72 EP - 66-72 PB - The Institute SN - 13351842 KW - stars: chemically peculiar KW - stars: variables: general KW - surveys KW - techniques: photometric N2 - The research on variable stars has significantly benefited from the availability of long-term photometric time series data from ground- and space-based surveys. Precise and long-term stable data allow the investigation of variable stars with small amplitudes and long periods, and the research on multi-periodic objects has profited greatly from the availability of quasi-uninterrupted time series data from space-based mission. To illustrate this situation, we have chosen to present our efforts to investigate the photometric variability of magnetic chemically peculiar stars using data from six different survey sources (ASAS-3, CoRoT, KELT, Kepler, Kepler-K2 and SuperWASP). Due to their range of periods (0.5 days to several years) and photometric amplitudes (sub-mmag range to about 0.1 mag), these objects constitute a challenge to observers. Long-term instrumental stability and a sufficient phase coverage are needed to detect and investigate this kind of variability. ER -
