Using Pulsar Timing to Detect Exoplanets Around Pulsars

[@DGPPhysics]

Interesting videos! Great Channel! There is a recent paper talk about a possible circum-Ternary planet around a pulsar+WD+WD PSR J0337+1715 if confirmed, far as I read the paper the planet hypothesis is more likely. The planet candidate got half of Moon mass, they stated the another likely possibility would be a “Achromatic red noise” could please explain us, I didn’t get it, the paper name is: “Explanation of the exceptionally strong timing noise of PSR J0337+1715 by a circum-ternary planet and consequences for gravity tests”
