SUMMARY:Watch Giant Worlds Form and Grow — A Direct Imaging Perspect
 ive\, Astronomy Colloquium\, Yifan Zhou\, University of Virginia
DESCRIPTION:Recent advances have greatly enhanced our understanding of
  gas giant planet formation and evolution\, with discoveries spanning 
 the onset of formation in protoplanetary disks\, direct detections of 
 gas accretion\, and constraints on the thermal\, dynamical\, and atmos
 pheric evolution of gas giants. These findings provide crucial insight
 s into the mechanisms underlying the formation of giant planets and th
 e ways these planets impact the formation environment and the broader 
 planetary systems.<br>
\n<br>
\nThis talk will review key direct imagi
 ng observations of young gas giant systems\, focusing on the identific
 ation of protoplanets\, the monitoring of accretion onto young planets
 \, and the empirical constraints of the thermal and angular momentum p
 roperties of giant planets. Using the PDS 70 system\, the only known p
 lanetary systems with two actively accreting planets\, as a case study
 \, I will illustrate how time-domain\, high-contrast imaging can revea
 l critical details of gas giant formation. I will also highlight ongoi
 ng and upcoming James Webb Space Telescope programs that promise trans
 formative insights into the mass growth and early evolution of giant p
 lanets.
