SUMMARY:Moons\, Planets\, and Suns in Context: Environments & Evolutio
 nary Pathways\, Astronomy Talk: Melinda Soares-Furtado\, Melinda Soare
 s-Furtado\, University of Wisconsin-Madison
DESCRIPTION:The growing population of exoplanets and the expanding rep
 ertoire of instruments and analysis techniques make it possible to exa
 mine moons\, planets\, and suns within the context of their environmen
 ts and evolutionary history. In this talk\, I discuss how my team leve
 rages stellar evolutionary models\, observational survey data\, and st
 atistical methods to probe the interactions and evolution of moons\, p
 lanets\, and suns. More specifically\, I present the effects of planet
 ary collision\, accretion\, and engulfment on stellar hosts\, identify
 ing the ingestion-derived signatures that make it possible to detect s
 uch events. In the second part of my talk\, I focus on my team’s inv
 estigations of young stars in co-moving groups and clusters. Since ste
 llar systems are more dynamically active at early times\, these enviro
 nments offer important test beds to explore star-planet interactions. 
 I present the results of my team’s efforts to characterize star-plan
 et systems at early stages of evolution (< 500 Myr) and the value thes
 e data offer to the broader scientific community. Looking forward\, in
 frared space-based missions will soon make it possible to detect trans
 iting exomoons orbiting young (<5 Myr)\, free-floating planets. Such o
 bservations will help to constrain the formation pathways and dynamica
 l histories of these extraordinary systems. In the last part of my tal
 k\, I discuss my team’s efforts to identify and characterize exosate
 llite populations and the broader implications of our anticipated resu
 lts.
