Evolution of sunspots seen in molecular lines. I

Abstract

With a view to asses the role of changing magnetic field strengths on line intensities, the results of equivalent width calculations of some lines of C₂, MgH and TiO molecules are presented here for standard photospheric and sunspot model atmospheres. Such an approach is expected to throw some light on evolution of sunspots and on a better structuring of semi-empirical sunspot models by way of correct evalution of scattered photospheric light.
