Recent exoplanet surveys from the ground have discovered myriad nearby systems that are non-transiting. Currently, the number of known non-transiting systems dominate by a factor of two compared to transiting ones within 20 pc, and by a factor of 9x within 10 pc. It is expected that the number of detected non-transiting planets will continue to grow in the coming years with more high-precision radial velocity surveys, next-generation direct imaging capabilities, Gaia astrometry, and the launch of flagship space missions like the Roman Space Telescope. This interdisciplinary symposium will focus on exploring pathways to characterize non-transiting planets - in particular, the regions of planetary parameter space that are not well represented in transiting planet characterization studies. The goal will be to engage communities working with ground- and space-based observational methods as well as contextualizing theoretical models to prepare for the characterization of these planets in the next decade.

Focus Topics:

• Observations of Nearby Non-Transiting Planets: Phase Curves, Radial Velocity, Astrometry, Direct Imaging
• Demographics of Non-Transiting Planet Population: Microlensing, Radial Velocity, Astrometry
• Characterization: Planetary Parameters, Atmospheres, and System Architectures Using Space-based
  and Ground-based Approaches
• Theory and Modeling of Non-Transiting Planets
• Science Priorities, Technology Gaps, Instruments and Missions

Due to space limitations, the symposium attendance will be limited to 160 attendees.

This symposium is a hybrid meeting. Remote participation is available.
