SUMMARY:It's About Time:  Exploring Planet Evolution with the Zodiacal Exop
 lanets In Time (ZEIT) Project
DESCRIPTION:It's About Time:  Exploring Planet Evolution with the Zodiacal 
 Exoplanets In Time (ZEIT) Project\nProf. Eric Gaidos\n\nTime is one of the
  least explored dimensions of exoplanet research; most stars targeted by l
 arge surveys are middle-aged by  necessity or statistics. Yet the first fe
 w hundred million years of a planetary system are probably the most format
 ive and include  accretion, migration, and escape of atmospheres.  While t
 he Kepler  prime field included a small number of young stars by chance, t
 he K2  mission is deliberately selecting some target stars by age, and  pr
 eviews the potential of TESS and PLATO.  The Zodical Exoplanets in  Time (
 ZEIT) project studies K2 systems in stellar clusters of established ages. 
  Transiting planets as small as Earth-size have been  detected in the Uppe
 r Scorpius, Pleiades, Hyades, and Praesepe clusters.  Mysterious aperiodic
  signals related to circumstellar disks  were found in Upper Scorpius, the
 se may be related to planet  formation. We are also investigating planets 
 around evolved stars and  report a Jupiter-mass planet inflated by irradia
 tion from its host  star. Gaia distances, proper motions, and spectra can 
 identify large numbers of young stars for observation by the TESS and PLAT
 O missions,  enabling robust comparisons across a range of ages to underst
 and  evolutionary trends, and select propitious targets for follow-up by  
 ELTs and space observatories such as JWST.
