Rare & notable finds

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

Already known: in SIMBAD as Gaia DR3 3711312340332547456 (PM*); the catalogued variable LINEAR 9227092 (EA, 67" away) has the same period - its light leaks into TESS's big pixels; same period as the known variable LINEAR 9227092. 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 3799.29 that fits the gravitational-lens shape better than a flare (Einstein time 29.5 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 10.1 hours - ultra-short-period planets are found around only ~0.5% of stars (if the signal is a real planet - it hasn't passed the planet check).
  • Hot Neptune desert notable
    A 4.6 Earth-radius planet on a 0.42-day orbit sits in the 'hot Neptune desert', where very few planets are known (if the signal is a real planet - it hasn't passed the planet check).
  • 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: Microlensing (rogue planet?); Ultra-short-period planet; Hot Neptune desert (in SIMBAD as Gaia DR3 3711312340332547456 (PM*); the catalogued variable LINEAR 9227092 (EA, 67" away) has the same period - its light leaks into TESS's big pixels). WARNING: same period as the known variable LINEAR 9227092 67" away; the signal is probably its light leaking in. Found automatically by hunt.py in TESS sector 23 (flagged in 1 sector(s)). Detection score 58.5. 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.
