SUMMARY:Moons\, Planets\, and Suns in Context: Environments & Evolutio
 nary Pathways\, Physics Department Colloquium\, Melinda Soares-Furtado
 \, UW Madison
DESCRIPTION:In early December we will be interviewing our very own Mel
 inda Soares-Furtado for a tenure-track faculty position in the Departm
 ents of Astronomy and Physics. As part of the interview process\, we h
 ave scheduled a special talk by Melinda as follows:<br>
\nMoons\, Plan
 ets\, and Suns in Context: Environments & Evolutionary Pathways<br>
\n
 <br>
\nThe growing population of exoplanets and the expanding repertoi
 re of instruments and analysis techniques make it possible to examine 
 moons\, planets\, and suns within the context of their environments an
 d evolutionary history. In this talk\, I discuss how my team leverages
  stellar evolutionary models\, observational survey data\, and statist
 ical methods to probe the interactions and evolution of moons\, planet
 s\, and suns. More specifically\, I present the effects of planetary c
 ollision\, accretion\, and engulfment on stellar hosts\, identifying t
 he ingestion-derived signatures that make it possible to detect such e
 vents. In the second part of my talk\, I focus on my team’s investig
 ations of young stars in co-moving groups and clusters. Since stellar 
 systems are more dynamically active at early times\, these environment
 s offer important test beds to explore star-planet interactions. I pre
 sent the results of my team’s efforts to characterize star-planet sy
 stems at early stages of evolution (< 500 Myr) and the value these dat
 a offer to the broader scientific community. Looking forward\, infrare
 d space-based missions will soon make it possible to detect transiting
  exomoons orbiting young (<5 Myr)\, free-floating planets. Such observ
 ations will help to constrain the formation pathways and dynamical his
 tories of these extraordinary systems. In the last part of my talk\, I
  discuss my team’s efforts to identify and characterize exosatellite
  populations and the broader implications of our anticipated results.<

\nThe talk will be at 2pm on Wednesday December 7th\, in St
 erling 4421. <br>
\nCoffee and cookies will be served at 1:45pm.
