PHANTOM Candidate TIC 466277979: A 2.34506-Day Transit Signal in TESS Photometry

Status: planet candidate. A periodic transit-like signal on TIC 466277979 found by PHANTOM (Planet Hunting Across Noisy TESS Observations and Measurements), an independent search of NASA TESS photometry. It has not been confirmed as a planet: its source star and nature are not yet established by follow-up observations (see Unresolved). Version 1.0 of this record. TIC: 466277979 Star: Tmag 15.01, Teff 3209 K, radius 0.312 ± 0.010 R☉, distance 125.8 pc (TIC v8) Period: 2.3450599 ± 0.0000026 d Mid-transit epoch: BJD_TDB 2461104.5427 ± 0.0011 Depth: 12,427 ± 814 ppm Duration: 1.441 ± 0.094 h Radius if on the target: 3.52 +0.15/−0.16 R⊕ (the detailed review's physical fit with the star's density as a prior: its Rp/Rs × the TIC stellar radius, both uncertainties) Transits meeting the fit's coverage criterion: 76 in TESS sectors 13, 27, 67, 94, 101, 102, 103, 104 Detection S/N: 17.8 (PHANTOM's search) The full record, with the evidence, uncertainties, data sources, cross-matches, unresolved questions and publication history, is README.md in this deposit.
