Investigated
The TESS Follow-up Observing Program (TFOP) is an international astronomy collaboration supporting TESS by confirming planet candidates, rejecting false positives, refining stellar and planetary properties, and measuring masses. Its formal network is organized into five areas: seeing-limited photometry, reconnaissance spectroscopy, high-resolution imaging, precise radial velocities, and space-based photometry, with observations from many facilities. Citizen-science networks such as Unistellar add distributed observations that can improve transit timing and help identify false positives, especially for planets with long or difficult-to-predict transits. The main distinction is between the centrally coordinated TFOP structure and broader community networks that contribute observations through citizen-science or other participation routes.

Lens adapted to this topic: The official coordination model and its scientific functions
The mainstream account treats TESS follow-up as a mission-linked, internationally coordinated observing program. TFOP organizes complementary observations to vet TESS Objects of Interest, establish reliable stellar parameters, confirm planets, refine radii, and obtain masses. Its structure is designed to coordinate professional facilities and reduce redundant work while supporting TESS’s primary science requirements.

Lens adapted to this topic: Community networks extending formal TESS follow-up
A broader account emphasizes that TESS follow-up is not limited to the formal TFOP hierarchy. Citizen-science networks such as Unistellar distribute observations across geographically separated observers, helping capture additional transits and improve orbital predictions. These networks can complement professional follow-up, particularly when transits are long, infrequent, or difficult to schedule, while their contributions remain focused on defined scientific tasks such as timing and false-positive checks.
