Transiting Exoplanet Meetings

Linking Exoplanet and Disk Compositions

This workshop will gather scientists working on the compositional characterization of planets and planet-forming regions in protoplanetary disks. Recent and upcoming advancements make it timely to have a round-table conversation among the several communities involved, to join forces in tackling our most compelling questions on the origins of exoplanet diversity. Do exoplanet compositions retain the imprint of large-scale disk processes? Do disks include compositional trends that imprint on planets? What do we learn in this context from observations of Solar System bodies? And what can we test with observations of disks and exoplanets in the near future? We intend to identify long-lasting and observable links between exoplanet and disk compositions, to help the community in shaping the essential parameter space to cover with existing and upcoming observatories for exoplanet and disk characterization.

Enabling Transiting Exoplanet Science with JWST

This workshop provided a forum for the transiting exoplanet community to learn about and discuss the capabilities of JWST to characterize transiting exoplanets. Talks informed potential observers about the cutting edge science that JWST will enable. Discussion sessions allowed for community dialog on how best to enable transiting exoplanet science with JWST. As JWST proposal opportunities approach, this workshop served as an important opportunity to understand how JWST will impact the field of transiting exoplanet science.

NASA's flagship observatories have provided many successes in transiting exoplanet exploration. These missions, like Hubble and Spitzer, have directly led to new discoveries of transiting exoplanets, their properties and has enhanced knowledge of exoplanetary atmospheres. Among the many discoveries are:

  • Confirmation of secondary eclipses
  • Identification of molecules and atoms
  • Primary eclipse detection
  • Day-Night temperature gradients
  • Atmospheric escape

Spitzer IRAC High Precision Photometry

The New Capabilities Provided by JWST

JWST is ~ 100 times more powerful than the Hubble and Spitzer observatories. It has greater sensitivity, higher spatial resolution in the infrared, and significantly higher spectral resolution in the mid infrared.
