Transit candidateProbably noise

Notes

Probably noise or an instrument effect. Found automatically by hunt.py in TESS sector 4 (flagged in 2 sector(s)). Detection score 1114.2. 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.

✦ Artist's impression

AI-painted · made locally

What this picture shows

Artist's impression of an UNCONFIRMED candidate, based on its measured data. Two stars of about 6,100 K and 3,100 K (2.6 and 1.6 times the Sun's radius, ~1.1 and ~0.6 solar masses) orbit each other every 31.2 hours, 4.2 million km apart (the Sun-Mercury distance is 58 million km). We see the orbit at 56 degrees (90 = exactly edge-on), close enough to edge-on that they eclipse each other. Sizes, separation, tilt and colours come from fitting the TESS eclipses (see the model-fit plot) plus Gaia's temperature; masses assume normal main-sequence stars. The painted look, surface detail and background were added by a locally run image AI; the stars' sizes, colours and spacing follow the measured data. The secondary eclipse arrives 94 minutes earlier than half an orbit after the primary, a sign of a slightly oval (eccentric) orbit: e*cos(omega) = -0.0785.

How it was made

Painted by an image AI (DreamShaper XL, a Stable Diffusion XL model) running locally on a home PC, over a 3D layout built from the measured data. No cloud services.

Where it sits among the stars

ESA Gaia colour and true brightness. Grey: every Star Log candidate. Orange: this star.
