A constant dip period near 1.81644 days fits Gaia DR3 and TESS sector 91 data for Gaia-TROI-005
We test the dip times and source location of Gaia-TROI-005, a known Gaia candidate also called TIC 435052739. We use 36 accepted Gaia DR3 G measurements, TESS sector 91 images, and the QLP light curve. A constant period model near 1.81644 days connects the Gaia and TESS dips. The catalog period predicts the TESS reference dip about 10.54 hours late after 1,821 cycles. This is a revised prediction of dip times, not evidence of a physical period change. The direct pixel sum contains 11 primary dips with a fitted depth of 1.485% and a duration of about 3.20 hours. The QLP detrended flux gives a depth of 1.029%, about 34% below the QLP aperture depth. The tested local baselines give direct depths from 1.37% to 1.53%. A weak half-phase feature depends on the baseline and does not establish a secondary eclipse. The primary difference image puts the lost light near a source group that includes a star 3.31 arcseconds away. The TESS data do not resolve these stars. We report a revised dip period and a measured dependence of depth on data reduction. We do not confirm a planet or identify the host star. The package contains the exact public input files, source queries, hashes, code, event measurements, sensitivity checks, and figures for an offline repeat.
