Inferring stellar metallicity and elemental abundances from kinematic and spectroscopic data using machine learning -- Implications for exoplanet host stars
V. Adibekyan, B. M. T. B. Soares, S. G. Sousa +7
(abridged) Elemental abundances of FGK stars can be derived routinely from high-resolution optical spectra, but this remains considerably more difficult for cooler stars. Machine-l…

Assessing the processes behind planet engulfment and its imprints
B. M. T. B. Soares, V. Adibekyan, C. Mordasini +5
Throughout a planetary system's formation evolution, some of the planetary material may end up falling into the host star and be engulfed by it, leading to a potential variation of…

Linking the primordial composition of planet building disks to the present-day composition of rocky exoplanets
V. Adibekyan, M. Deal, C. Dorn +16
The composition of rocky planets is strongly driven by the primordial materials in the protoplanetary disk, which can be inferred from the abundances of the host star. Understandin…
