I.; Gao, X. D.; Bland-Hawthorn, J.; Silva, G. M. De; Kos, J.; Lewis, G. F.; Martell, S. L.; Sharma, S.; Simpson, J. D.; Zucker, D. B.; Čotar, K.; Horner, J.; collaboration, the GALAH (2020-10-06)
      Massive sets of stellar spectroscopic observations are rapidly becoming available and these can be used to determine the chemical composition and evolution of the Galaxy with unprecedented precision. One of the major ...

    • Non-LTE abundance corrections for late-type stars from 2000Å to 3μm I. Na, Mg, and Al 

      Lind, K.; Nordlander, T.; Wehrhahn, A.; Montelius, M.; Osorio, Y.; Barklem, P. S.; Afsar, M.; Sneden, C.; Kobayashi, C. (2022-09-28)
      It is well known that cool star atmospheres depart from local thermodynamic equilibrium (LTE). Accurate abundance determination requires taking those effects into account, but the necessary non-LTE calculations are often ...
