TESS transit candidates and other TESS results, 2026

Transit timing, light-curve tables, false-positive checks, TRICERATOPS runs and predicted transit times for five transit candidates found in TESS full-frame images: TIC 402710280 (Gaia DR3 5828441289812582400; P = 36.34005 d, depth about 1680 ppm, 5.3 h, transit-timing variations up to 29 min; two archival HARPS epochs), TIC 324429952 (Gaia DR3 6416596855786566528; P = 42.37574 d, depth about 1500 ppm), TIC 89247735 (Gaia DR3 6708071581514074368, SCR J1820-4533; P = 18.32317 d, dilution-corrected depth 1.13-1.22 %, 4.5 h, Rp about 8.7 Earth radii with the stellar radius from an SED fit) and TIC 455017950 (HD 134147, HIP 74344, Gaia DR3 5825217968423162752; P = 40.60565 d, dilution-corrected depth about 1310 ppm, 4.7 h, Rp about 3.2 Earth radii; SOAR speckle limits from the literature) and TIC 311179599 (Gaia DR3 5801882036668103680, UCAC4 072-033588; M0 dwarf at 47.5 pc; P = 24.82684 d, dilution-corrected depth about 1435 ppm, 3.1 h, Rp about 2.5 Earth radii; eight transits, of which the sector-39 transit lies 2.2 h before the linear ephemeris of the other seven; a transit-timing variation is not established; three further events form a candidate second transit signal, about 880 ppm, 5.4 h, Rp about 2.0 Earth radii, P = 73.8672 d or 36.9336 d, TRICERATOPS FPP 0.047 and 0.038). Three further results: the eclipsing binary TIC 11613676 (CD-30 448, Gaia DR3 5029330944688623360; P = 12.1158 d), whose eclipses were absent in TESS sector 3 (2018), present in sector 30 (2020), 5.4 % and 2.2 % deep in sector 97 (2025) and shallower in sectors 104 and 106 (2026), with eclipse-timing variations; and TOI-540 b (TIC 200322593), whose transits, present in TESS sectors 4-32, are not detected in TESS sector 98 (2025-2026), with the checks made and the ground-based transit windows that would test the observation. The eclipsing binary TIC 124751008 (2MASS J06162084-3509125, Gaia DR3 2885572716963709952; P = 12.6118 d), an M-dwarf multiple at 57 pc, whose primary eclipses were 2.25 % deep in 2018, 0.28 % in sector 87 (2024-2025) and 0.77 % in sector 109 (2026), whose 2019 secondary eclipse has not been detected since 2021, and whose eclipse times change by up to 43 min between consecutive cycles; the geometric models require a change of the orbital inclination with a minimum near 2024.3. Nine eclipsing binaries without a previous eclipse report in the catalogues checked: TIC 13957664 (TYC 7587-159-1, Gaia DR3 4823456527782443392), a single 2.0 % eclipse at the conjunction predicted by its Gaia DR3 astrometric+spectroscopic orbit (P = 245.66 d, i = 91.1 +- 0.8 deg); TIC 304936165 (TYC 8385-1304-1), an eccentric 61.7-d Gaia SB1 with one eclipse per orbit near periastron; the eclipsing Gaia SB1s TIC 120522352 (8.517 d), TIC 382523691 (4.915 d), TIC 261702897 (6.934 d) and TIC 265436769 (15.475 d), whose eclipse periods match the spectroscopic periods; CPD-62 2890 (TIC 433642561) in the open cluster NGC 4609, with 17-27 % eclipses and P = 356.18/n d; and the 1.7075-d eclipsing binary TIC 245068282, which shares the parallax and proper motion of a G dwarf 13.2 arcsec away (hierarchical triple); and TIC 342194997 (TYC 9251-1375-1, Gaia DR3 5840649029966569088), a known Gaia DR3 astrometric+spectroscopic binary (P = 550.75 d, e = 0.837) at 46.7 pc, with a single 17 % eclipse by its M-dwarf companion at the conjunction predicted by the orbit. The values of these nine come from the vetting record, exported to data/notable_ebs_2026.csv; no spectroscopy was obtained. The tables of the other results are recomputed from public MAST, Gaia and ESO archive products by the scripts in the repository. AI-produced, not peer reviewed; the candidates are not confirmed.
