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…
The Twentieth Data Release of the Sloan Digital Sky Survey: First All-Sky BOSS Spectra, eROSITA-SDSS-V Mapper Coordinated Observations, and a Preview of the Local Volume Mapper
SDSS Collaboration, Mojgan Aghakhanloo, David Aguilar +273
This paper presents the twentieth data release (DR20) from the Sloan Digital Sky Survey, the third data release of its fifth generation (SDSS-V). SDSS-V is a panoptic spectroscopy…
On the evolutionary history of a simulated disc galaxy as seen by phylogenetic trees
Danielle de Brito Silva, Paula Jofré, Patricia B. Tissera +12
Phylogenetic methods have long been used in biology, and more recently have been extended to other fields - for example, linguistics and technology - to study evolutionary historie…
Assembling a high-precision abundance catalogue of solar twins in GALAH for phylogenetic studies
Kurt Walsen, Paula Jofré, Sven Buder +13
Stellar chemical abundances have proved themselves a key source of information for understanding the evolution of the Milky Way, and the scale of major stellar surveys such as GALA…
Two sequences in the age-metallicity relation as seen from [C/N] abundances in APOGEE
Paula Jofre
The age-metallicity relation is fundamental to study the formation and evolution of the disk. Observations have shown that this relation has a large scatter which can not be explai…
Using heritability of stellar chemistry to reveal the history of the Milky Way
Holly Jackson, Paula Jofre, Keaghan Yaxley +3
Since chemical abundances are inherited between generations of stars, we use them to trace the evolutionary history of our Galaxy. We present a robust methodology for creating a ph…
Galactic Phylogenetics
P. Jofre, P. Das
Phylogenetics is a widely used concept in evolutionary biology. It is the reconstruction of evolutionary history by building trees that represent branching patterns and sequences.…
Cosmic phylogeny: reconstructing the chemical history of the solar neighbourhood with an evolutionary tree
Paula Jofre, Payel Das, Jaume Bertranpetit +1
Using 17 chemical elements as a proxy for stellar DNA, we present a full phylogenetic study of stars in the solar neighbourhood. This entails applying a clustering technique that i…
Gaia FGK Benchmark Stars - Metallicity
Paula Jofre, U. Heiter, C. Soubiran +22
To calibrate automatic pipelines that determine atmospheric parameters of stars, one needs a sample of stars -- ``benchmark stars'' -- with well defined parameters to be used as a…
