SUMMARY:High Fidelity Spectroscopy of Exoplanet and Protoplanetary Dis
 k Atmospheres\, Astronomy Colloquium\, Geoffrey A. Blake\, California 
 Institute of Technology
DESCRIPTION:The extraordinary range of conditions in protoplanetary di
 sks drives complex patterns of atomic\, molecular\, and dust abundance
 s - especially for abundant 'volatile' species such as water\, carbon 
 monoxide\, and small organics that condense at different spatial locat
 ions\, or 'snowlines' in the disk. The bulk composition of planets can
  thus vary\, compared to that of their host star\, depending on their 
 origin and migration history.  The latest generation of Adaptive Optic
 s (AO)-fed infrared spectrographs now provide sufficiently high dynami
 c range capabilities to robustly characterize exoplanetary and protopl
 anetary disk atmospheres. This talk will present an overview of recent
  results from Keck Planet Imager and Characterizer (KPIC)-NIRSPEC stud
 ies of exoplanet/brown dwarf atmospheres and those from the JWST Infra
 red Spectroscopic Chemistry Survey (JDISCS) conducted with Mid-InfraRe
 d Instrument (MIRI) IFU.
