Rare & notable finds

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

Already known: in SIMBAD as UCAC4 851-014145 (Y*?); catalogued variable star nearby: Gaia DR3 2292116431175622784 (RS), 184" away. The rare-find check confirms what is on record - still nice, but not a new discovery.

Young 'dipper' star notable
6 deep dips at irregular times, depths from 2.4% to 54.8%. Gaia places it above the main sequence (young): dust clumps in its planet-forming disk are the usual cause.
Lopsided transit hint
The end of the transit is deeper than the start: a dust tail (disintegrating planet), rings, a fast-spinning star, or a blend.

Notes

Probably noise or an instrument effect. Rare, already known: Young 'dipper' star; Lopsided transit (in SIMBAD as UCAC4 851-014145 (Y*?); catalogued variable star nearby: Gaia DR3 2292116431175622784 (RS), 184" away). Found automatically by hunt.py in TESS sector 20 (flagged in 6 sector(s)). Detection score 232.4. 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. Updates: 2026-10-11 Planet check: Probably noise or an instrument effect 2026-10-11 Rare-find check: Lopsided transit; Young 'dipper' star 2026-10-11 Found by the automatic search in TESS sector 20
