Description

I present a progress report on including all the lines in the line lists, including all the lines in the opacities, and including all the lines in the model atmosphere and spectrum synthesis calculations. The increased opacity will improve stellar atmosphere, pulsation, stellar interior, asteroseismology, nova, supernova, and other radiation-hydrodynamics calculations. At present I have produced atomic line data for computing opacities for 544 million lines for elements up through Zn. Of these, 2.11 million lines are between known energy levels so have good wavelengths for computing spectra. Work is continuing on heavier elements. I also report on using stellar spectra as the laboratory source for extending analyses to higher energy levels. Data for each ion and merged line lists are available on my website kurucz.harvard.edu.
