Comparing phylogenetic trees of stars with spectral graph distances
Theosamuele Signor, Matias Neto, Paula Jofré +9
Phylogenetic trees offer a hierarchical representation of chemical similarities among stars, from which their evolutionary histories can, in principle, be reconstructed. Simulation…
Towards model-free stellar chemical abundances. Potential applications in the search for chemically peculiar stars in large spectroscopic surveys
Theosamuele Signor, Paula Jofré, Hernan Lira +3
Chemical abundance determinations from stellar spectra are challenged by observational noise, limitations in stellar models, and departures from simplifying assumptions. While trad…
A baseline on the relation between chemical patterns and birth stellar cluster
Theosamuele Signor, Paula Jofré, Luis Martí +1
The chemical composition of a star's atmosphere reflects the chemical composition of its birth environment. Therefore, it should be feasible to recognize stars born together that h…
