    Is LTE a Suitable Approximation for Fe I - based Diagnostics of the Thermal Structure of Sunspots?
    NLTE effects in iron lines are carefully investigated for the sunspot umbral model of Maltby et. al. (1986). Our model atom is realistic: it has hundreds of...

    Polarizing properties of grazing-incidence X-ray mirrors - Comment
    We show that grazing-incidence telescopes, like those used for X-ray imaging, present negligible instrumental polarization. This property does not depend on the...
