A Threshold-level Transit-like Signal in TESS Photometry of the Nearby M Dwarf TIC 71150324

Year: 2026

Type: preprint

Abstract: A weak, threshold-level transit-like signal in TESS photometry of the M dwarf TIC 71150324: P = 8.42216 d, depth about 1.6 ppt (2.2 ppt crowding-corrected), about 2.1 to 2.5 Earth radii if on the target, seen in three observing seasons. SNR 6.3 to 8; TRICERATOPS FPP 0.17; an unexplained 2.4 to 2.9 sigma dip at phase 0.5. It is a weak candidate, not a confirmed planet; no statistical validation is claimed. The PDF includes every vetting figure with captions; ground-based tests are preregistered.
