Identifying solar-like magnetic cycles with Zeeman-Doppler-Imaging (ZDI)
Lisa T. Lehmann, Gaitee A. J. Hussain, Aline A. Vidotto +2
We are reaching the point where spectropolarimetric surveys have run for long enough to reveal solar-like magnetic activity cycles. In this paper we investigate what would be the b…
How much do underestimated field strengths from Zeeman-Doppler imaging affect spin-down torque estimates?
Victor See, Lisa Lehmann, Sean P. Matt +1
Numerous attempts to estimate the rate at which low-mass stars lose angular momentum over their lifetimes exist in the literature. One approach is to use magnetic maps derived from…
Measuring stellar magnetic helicity density
K. Lund, M. Jardine, L. T. Lehmann +10
Helicity is a fundamental property of a magnetic field but to date it has only been possible to observe its evolution in one star - the Sun. In this paper we provide a simple techn…
