Gaia DR3 156359727521343744

Eclipsing binaryKnown (independent confirmation)

Notes

Detached eclipsing binary, near-equal eclipses (~27% and ~23% deep). Secondary at phase 0.5, so the orbit is likely circular. Already catalogued by ASAS-SN and ATLAS; my TESS period matches Gaia to 0.002%.

✦ Artist's impression

What this picture shows

Artist's impression based on the measured data. Two stars of about 8,200 K and 7,800 K (1.8 and 1.7 times the Sun's radius, ~1.9 and ~1.8 solar masses) orbit each other every 46.2 hours, 7.0 million km apart (the Sun-Mercury distance is 58 million km). We see the orbit at 81 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 14 minutes earlier than half an orbit after the primary, a sign of a slightly oval (eccentric) orbit: e*cos(omega) = -0.0081.
