Atomic Transition Probabilities of Neutral Calcium
E. A. Den Hartog, J. E. Lawler, C. Sneden +3
The goals of this study are 1) to test the best theoretical transition probabilities for Ca I (a relatively light alkaline earth spectrum) from a modern ab initio calculation using…
linemake: An Atomic and Molecular Line List Generator
Vinicius M. Placco, Christopher Sneden, Ian U. Roederer +5
In this research note, we present linemake, an open-source atomic and molecular line list generator. Rather than a replacement for a number of well-established atomic and molecular…
Improved Atomic Transition Probabilities for UV and Optical Lines of Hf II and Determination of the Hf Abundance in Two Metal-Poor Stars
E. A. Den Hartog, J. E. Lawler, I. U. Roederer
We report new branching fraction measurements for 199 UV and optical transitions of Hf II. These transitions range in wavelength (wavenumber) from 2068- 6584 A (48322-15183 cm-1) a…
