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…
Estimating magnetic filling factors from Zeeman-Doppler magnetograms
Victor See, Sean P. Matt, Colin P. Folsom +15
Low-mass stars are known to have magnetic fields that are believed to be of dynamo origin. Two complementary techniques are principally used to characterise them. Zeeman-Doppler im…
Observing the simulations: Applying ZDI to 3D non-potential magnetic field simulations
L. T. Lehmann, G. A. J. Hussain, M. M. Jardine +2
The large-scale magnetic fields of stars can be obtained with the Zeeman-Doppler-Imaging (ZDI) technique, but their interpretation is still challenging as the contribution of the s…
Magnetic field measurements of Eridani from Zeeman broadening
L. T. Lehmann, A. Künstler, T. A. Carroll +1
We present new magnetic field measurements of the K2 main-sequence star Eridani based on principal components analysis (PCA) line-profile reconstructions. The aim of this paper…
