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…

Disentangling chemical evolution histories with phylogenetic trees

Rebeca Canales, Paula Jofré, Claudia Aguilera-Gómez +6

Chemical abundances encode the fossil record of galaxy evolution in a complex and diverse way that requires innovative approaches to reconstruct galactic histories. We investigate…

Reconstructing chemical enrichment pathways in disc galaxies: A phylogenetic approach

Brian Tapia-Contreras, Patricia B. Tissera, Emanuel Sillero +11

Phylogenetic methods, traditionally used in biology to trace the evolutionary relationships among species, are emerging as a powerful framework to reconstruct evolutionary processe…

A North-South Metallicity Asymmetry in the Outer Galactic disk -- Evidence for the Pericentric Passage of the Sagittarius Dwarf Galaxy

Chun Wang, Yang Huang, Timothy C. Beers +4

We present maps of the mean metallicity distributions on the Galactocentric -- plane at different azimuthal angles using red clump stars selected from the LAMOST and APOGEE s…

Studying stellar populations in Omega Centauri with phylogenetics

P. Jofré, C. Aguilera-Gómez, P. Villarreal +14

The nature and formation history of our Galaxy's largest and most enigmatic stellar cluster, known as Omega Centauri (ocen) remains debated. Here, we offer a novel approach to dise…

The accreted Galaxy: An overview of TESS metal-poor accreted stars candidates

Danielle de Brito Silva, Paula Jofré, Clare Worley +2

The Milky Way is a mosaic of stars from different origins. In particular, metal-poor accreted star candidates offer a unique opportunity to better understand the accretion history…

The Chemical Diversity of the Metal-Poor Milky Way

Nicole Buckley, Payel Das, Paula Jofré +2

We present a detailed study of the chemical diversity of the metal-poor Milky Way (MW) using data from the GALAH DR3 survey. Considering 17 chemical abundances relative to iron ([X…

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…
