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…
SWEET-Cat: A view on the planetary mass-radius relation
S. G. Sousa, V. Adibekyan, E. Delgado-Mena +9
SWEET-Cat (Stars With ExoplanETs Catalogue) was originally introduced in 2013, and since then, the number of confirmed exoplanets has increased significantly. A crucial step for a…
Composition of super-Earths, super-Mercuries, and their host stars
V. Adibekyan, N. C. Santos, C. Dorn +11
Because of their common origin, it was assumed that the composition of planet building blocks should, to a first order, correlate with stellar atmospheric composition, especially f…
SWEET-Cat 2.0: The Cat just got SWEETer; Higher quality spectra and precise parallaxes from GAIA eDR3
S. G. Sousa, V. Adibekyan, E. Delgado-Mena +13
Aims. The catalog of Stars With ExoplanETs (SWEET-Cat) was originally introduced in 2013. Since then many more exoplanets have been confirmed, increasing significantly the number o…
A compositional link between rocky exoplanets and their host stars
Vardan Adibekyan, Caroline Dorn, Sérgio G. Sousa +17
Stars and planets both form by accreting material from a surrounding disk. Because they grow from the same material, theory predicts that there should be a relationship between the…
