Rare & notable finds

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

Already known: catalogued variable star nearby: Gaia DR3 4515054996643167616 (L), 43" away. The rare-find check confirms what is on record - still nice, but not a new discovery.

Microlensing (rogue planet?) hint
A one-off, symmetric brightening at BTJD 2795.89 that fits the gravitational-lens shape better than a flare (Einstein time 41.2 h). This length points to a star or brown dwarf as the lens. Very rare in TESS data; scattered light and asteroids can mimic it.
Transits of a giant star notable
Gaia places this star among the giants: planets transiting giants are rare, and a big star makes even a large planet's dip tiny.

Notes

Probably noise or an instrument effect. Rare, already known: Microlensing (rogue planet?); Transits of a giant star (catalogued variable star nearby: Gaia DR3 4515054996643167616 (L), 43" away). Found automatically by hunt.py in TESS sector 14 (flagged in 1 sector(s)). Detection score 150.4. 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.
