Ariel stellar characterisation IV. Fundamental parameters of 18 hot stars in the Ariel mission candidate sample

H. Ramler, S. P. D. Borthakur, C. P. Folsom +16

The characterisation of exoplanetary systems depends on the accurate determination of host star parameters. The Ariel mission will probe the atmospheres of a statistically signific…

Portrait of a Galaxy on FIRE: Is the -bimodality a natural consequence of inside-out disc growth in a hierarchical formation scenario?

María Benito, Annaliina Aavik, Giuseppina Battaglia +7

The chemical dichotomy in the [/Fe]-[Fe/H] plane is a consequence of the complex processes underlying the formation and evolution of disc galaxies such as observed in the stell…
