Detection of polarization from the E^4Π-A^4Πsystem of FeH in sunspot spectra

A. Asensio Ramos, J. Trujillo Bueno, M. Collados

Here we report the first detection of polarization signals induced by the Zeeman effect in spectral lines of the E^4Π-A^4Πsystem of FeH located around 1.6 $\mu$m. Motivated by the te…
