Descripción
The photospheric Mn I 539.4 nm line in the solar spectrum shows unusual
variability with the solar cycle in that its depth decreases with
increasing activity. citet{nv-2001A&A...369L..13D} claimed that this
phenomenon is due to interlocking between the chromospheric Mg II h
& k lines and an overlapping Mn I multiplet. In this contribution we
test this hypothesis by synthesizing Mn I 539.4 nm line including these
interlocking lines for a range of standard solar models and then
combining resulting profiles without and with interlocking to emulate
the full-disk profile variation. We find that the interlocking gives
only a minor contribution; the largest one comes from different
temperature stratifications in the photospheric layers of the various
models.
