PHANTOM Candidate TIC 160075227: A 4.17973-Day Transit Signal in TESS Photometry

Status: planet candidate. A periodic transit-like signal on TIC 160075227 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: 160075227 Star: Tmag 13.51, Teff 3766 K, radius 0.641 ± 0.019 R☉, distance 203.8 pc (TIC v8) Period: 4.1797319 ± 0.0000066 d Mid-transit epoch: BJD_TDB 2460162.44791 ± 0.00092 Depth: 3,909 ± 336 ppm Duration: 1.94 ± 0.10 h Radius if on the target: 4.34 +0.21/−0.21 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: 23 in TESS sectors 2, 28, 68, 69, 96 Detection S/N: 13.5 (PHANTOM's search) Open questions (README.md, Unresolved): Which star the signal comes from; No radial-velocity measurement precise enough for the planet; Not statistically validated. Earlier detections: DTARPS-S I (Melton+ 2024): DTARPS-S analysis-list signal, not in its candidate catalog, random-forest classifier score 0.57 (README.md, Prior detections).
