Rare & notable finds

Something unusual, worth a look - less certain than a significant find. How these checks work →

Already known: on NASA's TESS list as CTOI 349518145.01 (PC); in the TESS eclipsing-binary catalogue (Prsa et al. 2022) as TIC 0349518145; in SIMBAD as UCAC4 144-009991 (*); catalogued variable star nearby: Gaia DR3 5292230462723681792 (E, P = 1.0283 d), 201" away. The rare-find check confirms what is on record - still nice, but not a new discovery.

Lopsided transit hint
The start of the transit is deeper than the end: a dust tail (disintegrating planet), rings, a fast-spinning star, or a blend.
Dimming beside the transit hint
On average the star is 813 ppm dimmer just before and after the transit (16.4 sigma): what a moon (or ring/dust) travelling with the planet would cause. Instrument trends can do this too.

Checked, nothing found (10)

Notes

Already known to NASA: CTOI 349518145.01 (PC). Rare, already known: Lopsided transit; Dimming beside the transit (on NASA's TESS list as CTOI 349518145.01 (PC); in the TESS eclipsing-binary catalogue (Prsa et al. 2022) as TIC 0349518145). Already on NASA's TESS list as CTOI 349518145.01 (PC). Found automatically by hunt.py in TESS sector 29 (flagged in 18 sector(s)). Detection score 84.0. Not in VSX, ASAS-SN or ZTF variable catalogues at the time of the search; not in Gaia DR3's variable lists. Unchecked by hand yet: verify the period, nearby stars and a wider catalogue search.
