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 144284873.01 (PC); in SIMBAD as TYC 8020-98-1 (*). 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 4177.45 that fits the gravitational-lens shape better than a flare (Einstein time 101.1 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.
Ultra-short-period planet notable
One orbit takes 21.4 hours - ultra-short-period planets are found around only ~0.5% of stars.

Notes

Already known to NASA: CTOI 144284873.01 (PC). Rare, already known: Microlensing (rogue planet?); Ultra-short-period planet (on NASA's TESS list as CTOI 144284873.01 (PC); in SIMBAD as TYC 8020-98-1 (*)). Already on NASA's TESS list as CTOI 144284873.01 (PC). Found automatically by hunt.py in TESS sector 29 (flagged in 3 sector(s)). Detection score 81.1. 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.
