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…
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…
Density discrepancy between transit-timing variations and radial velocity: Insights from the host star composition
V. Adibekyan, S. G. Sousa, S. C. C. Barros +5
The determination of planetary densities from the masses derived with the radial velocity (RV) and transit-timing variation (TTV) methods reveals discrepancies. Specifically, plane…
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…
On the stellar clustering and architecture of planetary systems
V. Adibekyan, N. C. Santos, O. D. S. Demangeon +9
Revealing the mechanisms shaping the architecture of planetary systems is crucial for our understanding of their formation and evolution. In this context, it has been recently prop…
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…
