ATLAS9 Stellar Atmosphere Programs and 2 km/s grid.
Model atmospheres for G, F, A, B, and O stars
A grid of LTE model atmospheres is presented for effective temperatures ranging from 5500 to 50,000 K, for gravities from the main sequence down to the radiation pressure limit, for abundances solar,
New Grids of ATLAS9 Model Atmospheres
New opacity distribution functions (ODFs) for several metallicities have been computed. The main improvements upon previous ODFs computed by Kurucz (1990) are: (1) the replacement of the solar
Model Atmospheres for Population Synthesis
I have used my newly calculated iron group line list together with my earlier atomic and molecular line data, 58,000,000 lines total, to compute new opacities for the temperature range 2000K to
A new sunspot umbral model and its variation with the solar cycle
Semiempirical model atmospheres are presented for the darkest parts of large sunspot umbrae, regions have called umbral cores. The approach is based on general-purpose computational procedures that
A major upgrade of the VALD database
Vienna atomic line database (VALD) is a collection of critically evaluated laboratory parameters for individual atomic transitions, complemented by theoretical calculations. VALD is actively used by
The nonsolar abundance ratios of Arcturus deduced from spectrum synthesis
Using opacity distribution functions based on a newly expanded atomic and molecular line list, we have calculated a model atmosphere for Arcturus that reproduces the observed flux distribution.

The disclosure relates to a method of bending elongated materials such as pipe by applying a compressive primary bending force to the material at locations on either end of the portion of the
