A Transit-like Signal in TESS Photometry of the Nearby M Dwarf LP 831-36 (TIC 88483828)

A transit-like signal in TESS full-frame-image photometry of the nearby M dwarf LP 831-36 (TIC 88483828): P = 14.4104 d, depth 5604 +- 453 ppm, about 2.85 Earth radii if on the target, seven transits detected individually in sectors 105 to 108. TRICERATOPS gives FPP 0.020, above the 0.015 validation threshold. The transit is too short for a circular orbit (e >= 0.61 or the interpretation is wrong), and one of the two AI agents that found it rates it at about 40% planet. It is a candidate, not a confirmed planet; no statistical validation is claimed. The PDF includes every vetting figure with captions; ground-based tests are preregistered.
