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 260756218.01 (PC); in the TESS eclipsing-binary catalogue (Prsa et al. 2022) as TIC 0260756218; in SIMBAD as UCAC4 112-127948 (*). The rare-find check confirms what is on record - still nice, but not a new discovery.

Superflare notable
A flare releasing roughly 3.2e+35 erg (rough, from TESS's band) on a Sun-like star - a 'superflare', more than 10x the biggest flare ever seen on the Sun.
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.
Planet around a young star notable
The star spins once every 1.0 days - fast for a 5800 K star, so it is probably young (a few hundred million years). Young planets show how planets change in their first years - few are known.

Checked, nothing found (10)

Notes

Already known to NASA: CTOI 260756218.01 (PC). Rare, already known: Superflare; Lopsided transit; Planet around a young star (on NASA's TESS list as CTOI 260756218.01 (PC); in the TESS eclipsing-binary catalogue (Prsa et al. 2022) as TIC 0260756218). Already on NASA's TESS list as CTOI 260756218.01 (PC). Found automatically by hunt.py in TESS sector 28 (flagged in 3 sector(s)). Detection score 99.0. 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.
