| Abstract: |
We present our analysis aimed at inferring average magnetic fields in
slowly-rotating solar-like stars.
Using the spectral line inversion code SPINOR, we perform
high-accuracy line profile fitting and investigate whether Zeeman
broadening can be reliably detected in optical data of unprecedented
quality.
We argue that our usage of both high- and low-geff lines
does provide a certain sensitivity to magnetic fields that
may, indeed, be detected.
However, the measurement is subject to a model dependence and prone to
ambiguities, e.g. due to spectral blends.
Hence, while a field may be successfully recovered, the quantification
of this field is subject to large uncertainties, even for the
highest-quality optical data. |
