Some Aspects of the calculation of Balmer lines in the sun and stars

Abstract

We compare the results of Balmer-line calculations using recent theory and improved computational algorithms with those from the widely-used SYNTHE and BALMER9 routines. The resulting profiles are mostly indistinguishable. Good fits to the normalized solar Balmer lines Hα through Hδ are obtained (apart from the cores) using the recent unified-broadening… (More)
