Lithium Enrichment in a Subgiant Star with a Brown Dwarf Companion: A Planetary Engulfment Candidate

Brooke Kotten, Melinda Soares-Furtado, Ricardo Yarza +11

Theoretical models predict that subgiants within a narrow mass regime can retain detectable lithium enrichment signatures from planetary engulfment. We test this prediction using T…

Searching for Exoplanets Born Outside the Milky Way: VOYAGERS Survey Design

Robert Aloisi, Andrew Vanderburg, Melinda Soares-Furtado +44

Observations over the past few decades have found that planets are common around nearby stars in our Galaxy, but little is known about planets that formed outside the Milky Way. We…
