PHANTOM Candidate TIC 179482603: A 4.34657-Day Transit Signal in TESS Photometry

Status: planet candidate. A periodic transit-like signal on TIC 179482603 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: 179482603 Star: Tmag 13.79, Teff 3597 K, radius 0.582 ± 0.018 R☉, distance 180.4 pc (TIC v8) Period: 4.3465693 ± 0.0000037 d Mid-transit epoch: BJD_TDB 2460071.90329 ± 0.00068 Depth: 18,229 ± 579 ppm Duration: 2.149 ± 0.063 h Radius if on the target: 8.45 +0.28/−0.28 R⊕ (physical fit's Rp/Rs × the TIC stellar radius, both uncertainties); ± 1.3 R⊕ more for the reduction-dependent dilution correction (on the same images the two photometries' depths differ by 34%, 16% in radius, 1.3 R⊕ at this size; see *Detailed review*): a working allowance, not a calibrated 68% interval Transits observed: 41 in TESS sectors 11, 37, 38, 64, 65, 99, 100, 101 Detection S/N: 42.4 (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.
