LTE or non-LTE, that is the question: The NLTE chemical evolution of strontium in extremely metal-poor stars
Context. Strontium has proven itself to be one of the most important neutron-capture elements in the study of metal-poor stars. Thanks to the strong absorption lines of Sr, they can be detected even in the most metal-poor stars and also in low-resolution
