TL;DR: In this article, the authors describe version 90 (C90) of the code, paying particular attention to changes in the atomic database and numerical methods that have affected predictions since the last publicly available version, C84.

TL;DR: The Dartmouth Stellar Evolution Database as mentioned in this paper is a collection of stellar evolution tracks and isochrones that spans a range of [Fe/H] from 2.5 to +0.5, [α/Fe] from 0.245 to 0.40, and initial He mass fractions from Y = 0.1 and 4 M

TL;DR: In this paper, the authors presented a new table for low-temperature Rosseland and Planck mean opacities from Alexander & Ferguson, which includes more grain species and updated optical constants.

TL;DR: In this paper, a new set of low-temperature opacity data has been assembled, and from this basic data set, Rosseland and Planck mean opacities have been computed for temperatures between 12,500 and 700 K. In addition to the usual continuous absorbers, atomic line absorption, molecular line absorption and grain absorption and scattering (by silicates, iron, carbon, and SiC) have been accounted for.

TL;DR: In this article, the authors present the extension of the NextGen model atmosphere grid to the regime of giant stars and discuss the effects of spherical geometry on the structure of the atmospheres and the emitted spectra.
