Light curve of the week: EB

Many stars are not alone, but instead form part of a multi-stellar system of two or more stars that are gravitationally bound together. Even though the prime science goal of TESS is to find exoplanets, it also observes a plethora of eclipsing binaries that allow us to study these systems in more detail.

LCOTW_8153514

The light curve of TIC 8153514, observed in Sector 21, shows a sharp eclipse superimposed on top of the signal of a variable star.

If you see eclipsing binaries on PHT you can tag it with #EB or #eclipsingbinary to let others known what you have found!
