SUMMARY:Investigating the Signatures of Substellar Ingestion\, Astrono
 my Colloquium\, Melinda Soares-Furtado\, UW Astronomy Department
DESCRIPTION:What are the observable effects induced by substellar inge
 stion? Do we have any hope of unambiguously detecting such signatures?
  In this talk\, I address these open questions\, describing my efforts
  to unveil stellar hosts that have ingested their substellar companion
 s within open cluster environments. Such sources will offer valuable c
 onstraints to test stellar evolutionary models. Moreover\, they will p
 rovide a rare opportunity to directly measure the bulk composition of 
 substellar companions. I will describe the challenges of modeling the 
 substellar disassociation process\, particularly as it pertains to den
 se brown dwarf companions. I will review promising engulfment-derived 
 chemical and rotational tracers. Lastly\, to detect these cannibal sta
 rs\, I will emphasize a need for targeted photometric and spectroscopi
 c surveys among stars in open clusters.<br>
