ExoFOP

ExoFOP is an online collaborative platform and database designed to coordinate follow-up observations of transiting exoplanet candidates and to centralize associated data, metadata, and analysis tools. It serves as a nexus connecting mission teams, ground-based observatories, and individual researchers to streamline characterization efforts for targets originating from space missions and surveys. The project operates within a networked ecosystem that includes observatories, survey teams, and archives to accelerate validation, vetting, and publication of exoplanet discoveries.

Overview

ExoFOP was developed to support follow-up activities for missions such as Kepler, K2, TESS, and to interface with legacy efforts from CoRoT and ground surveys like SuperWASP and HATNet. It functions alongside archival initiatives such as MAST and collaborates with institutions including NASA, Caltech, Harvard-Smithsonian CFA, and observatories like Keck Observatory and Palomar Observatory. The platform aggregates photometry, spectroscopy, high-resolution imaging, and target lists used by teams including the TESS Science Team, Kepler Science Team, and community-led consortia such as the Exoplanet Archive.

Data and Tools

The database ingests heterogeneous datasets from instruments on telescopes such as Gemini Observatory, Very Large Telescope, Subaru Telescope, and networks like Las Cumbres Observatory and Apache Point Observatory. Users can upload or query time-series photometry from missions including Spitzer Space Telescope and ground surveys like KELT and NGTS, radial velocity measurements from spectrographs such as HIRES, HARPS, and CARMENES, and high-contrast imaging from systems like NIRC2 and SPHERE. Integrated tools provide vetting diagnostics used by pipelines developed by groups at MIT, Princeton University, University of Cambridge, and University of Chicago, enabling cross-matching with catalogs such as Gaia and 2MASS. ExoFOP supports target prioritization schemes employed by follow-up programs associated with awards and initiatives like the NASA Hubble Fellowship and NSF-funded consortia, and it tracks observational metadata relevant to proposals submitted to facilities including NOIRLab and European Southern Observatory.

Observation and Follow-up Coordination

The platform facilitates coordination among principal investigators, instrument teams, and time allocation committees from facilities like Keck Observatory, Gemini Observatory, and Subaru Telescope by maintaining shared target lists, observation logs, and status flags used in programs led by groups at University of California, Berkeley, Yale University, and University of Oxford. Follow-up activities—photometric validation, centroid analysis, reconnaissance spectroscopy, precision radial velocity monitoring, and adaptive optics imaging—are carried out by consortia with ties to projects such as TESS Follow-up Observing Program (TFOP), the Kepler Follow-up Observation Program, and collaborations involving research centers like NASA Ames Research Center and Space Telescope Science Institute. ExoFOP’s coordination features reduce duplication of effort among teams collaborating on campaigns affiliated with awards like the Goddard Fellowship and international collaborations including the European Research Council projects.

Scientific Impact and Discoveries

By centralizing observations and vetting products, ExoFOP has contributed indirectly to the confirmation and characterization of planets reported by Kepler and TESS teams, aiding publications from laboratories at Caltech, University of Cambridge, MIT, and Pennsylvania State University. The consolidation of high-resolution imaging and radial velocity data has helped rule out false positives in cases tied to notable systems such as multi-planet hosts investigated by groups associated with Harvard-Smithsonian CFA and discoveries followed up at facilities like Keck Observatory and Gemini Observatory. ExoFOP-supported datasets have underpinned analyses published in journals produced by editors at organizations like American Astronomical Society and research presented at conferences such as the American Geophysical Union Fall Meeting and Winter AAS Meeting. Its role in coordinating follow-up has accelerated validation pathways that feed into catalogs maintained by the NASA Exoplanet Archive and influenced target selection strategies for missions including James Webb Space Telescope and proposed missions advised by panels at National Academies.

Access, Policies, and Contributions

Access to ExoFOP is managed to balance open science principles championed by institutions like NASA and data proprietary periods and embargo practices common to teams funded by agencies such as NSF and European Space Agency. Contributors range from mission teams at NASA Ames Research Center and Caltech to individual investigators at universities like University of Arizona and University of Washington, with policies for data sharing, tagging, and attribution aligned with community norms established at gatherings such as the Protostars and Planets conference. The platform accepts data submissions from instrument teams operating spectrographs like HIRES and imagers like NIRC2, and contributors are encouraged to credit co-investigators and institutions including NOIRLab and Space Telescope Science Institute in downstream usage.
