PHANTOM Candidate TIC 372318262: A 1.31851-Day Transit Signal in TESS Photometry

Status: planet candidate. A periodic transit-like signal on TIC 372318262 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: 372318262 Star: Tmag 14.07, Teff 3275 K, radius 0.186 ± 0.006 R☉, distance 46.5 pc (TIC v8) Period: 1.3185098 ± 0.0000013 d Mid-transit epoch: BJD_TDB 2461111.441 ± 0.0011 Depth: 4,917 ± 636 ppm Duration: 0.699 ± 0.088 h Radius if on the target: 1.27 +0.13/−0.10 R⊕ (the detailed review's physical fit with the star's density as a prior: its Rp/Rs × the TIC stellar radius, both uncertainties); ± 0.2 R⊕ more for the reduction-dependent depth: about half the difference between the radii the two reductions' depths on the same images imply (6,444 ± 1,155 and 4,104 ± 850 ppm in sectors 13 and 27, 1.63 and 1.30 R⊕ by the simple depth relation, a half-difference of 0.16 rounded up; see *Detailed review*): a working allowance, not a calibrated 68% interval. It assumes the dip is on the target with no dilution beyond the photometry's own and does not cover grazing configurations, another host or unresolved dilution Transits meeting the fit's coverage criterion: 88 in TESS sectors 27, 94, 101, 102, 104 Detection S/N: 11.8 (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.
