Finding a second Sun - How can we detect solar-like magnetic cycles with Zeeman-Doppler-Imaging (ZDI)?
Abstract
Spectropolarimetric surveys have now been running for long enough to reveal solar-like magnetic activity cycles, e.g., for 61 Cyg A (Boko Saikia et al. 2018). Our work examines if a solar-like cycle can be observed with ZDI, given that this technique only detects the large-scale field for very slowly-rotating and low-activity stars like our Sun. We aim to determine the best strategy to detect stellar cycles, and which parameters are most sensitive to cycle changes.This poster presents our paper: Lehmann, L.
