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…
Lithium in Kepler Red Giants: Defining Normal and Anomalous
Jamie Tayar, Joleen K. Carlberg, Claudia Aguilera-Gómez +1
The orders of magnitude variation in lithium abundances of evolved stars have long been a puzzle. Diluted signals, ambiguous evolutionary states and unknown masses have made it cha…
Cannibals in the thick disk II -- Radial-velocity monitoring of the young alpha-rich stars
P. Jofre, A. Jorissen, C. Aguilera-Gomez +6
Determining ages of stars for reconstructing the history of the Milky Way remains one of the most difficult tasks in astrophysics. This involves knowing when it is possible to rela…
Mass Matters: No Evidence for Ubiquitous Lithium Production in Low-Mass Clump Giants
Julio Chanamé, Marc H. Pinsonneault, Claudia Aguilera-Gómez +1
Known sources of lithium (Li) in the universe include the big bang, novae, asymptotic giant branch stars, and cosmic ray spallation. During their longer-lived evolutionary phases,…
On Lithium-6 as diagnostic of the lithium-enrichment mechanism in red giants
Claudia Aguilera-Gómez, Julio Chanamé, Marc H. Pinsonneault
High lithium-7 () abundances in giants are indicative of non-standard physical processes affecting the star. Mechanisms that could produce this signature include con…
On Lithium-Rich Red Giants. II. Engulfment on the Giant Branch of Trumpler 20
Claudia Aguilera-Gómez, Julio Chanamé, Marc H. Pinsonneault +1
The Gaia-ESO survey recently reported on a large sample of lithium (Li) abundance determinations for evolved stars in the rich open cluster Trumpler 20. They argue for a scenario w…
On Lithium-Rich Red Giants. I. Engulfment of Sub-Stellar Companions
Claudia Aguilera-Gómez, Julio Chanamé, Marc Pinsonneault +1
A small fraction of red giants are known to be lithium (Li) rich, in contradiction with expectations from stellar evolutionary theory. A possible explanation for these atypical gia…
