Gaia's detection of eclipsing binaries - explained

Показать описание

Published for Gaia Data Release 3 on 13 June 2022.

Top panel: Light curve, i.e. the flux seen by the observer as the sum of
the contributions from each element of the stars' surfaces.
Bottom-left panel: Simulated plane-of-sky view (in "false" colours).
Bottom-right panel: Discrete grids that represent the stars' surfaces.
Colour palettes indicate the temperature differences (with respect to each
star's effective temperature) due to gravity and mutual heating.
