Exoplanet Confirmation
Fourteen TESS candidates become nine planetary systems
Radial velocities and follow-up imaging validate a super-puff, an extremely eccentric world, and seven other systems while reclassifying five candidates as stars.

Accepted Study · Nine Systems Validated
A 64-author follow-up campaign combined TESS photometry, SOPHIE radial velocities, ground-based light curves, and high-resolution imaging to establish the nature of fourteen TESS Objects of Interest. Nine systems host planets; the other five contain low-mass stellar companions whose larger radial-velocity signals reveal eclipsing binaries rather than planets.
The validated sample includes six warm Jupiters, three hot Jupiters, and an additional outer companion. TOI-6842A b has a reported density of only 0.08 grams per cubic centimeter, placing it among the nine least-dense known planets, while TOI-7025 b follows an unusually eccentric orbit of 0.82 plus or minus 0.02. The paper is accepted in Astronomy & Astrophysics, but atmospheric characterization of the super-puff remains future work.
Why it matters
Candidate vetting is discovery, not housekeeping. The same observations that reject five false positives also uncover rare worlds that are unusually useful for testing planetary inflation and migration.
What the source establishes
Accepted paper posted October 6. Planet status is supported by several observing methods; super-puff density and eccentricity retain the uncertainties reported by the authors.
