The tilt of the bulge is the thing: Poon et al. on “A potential exomoon from the predicted planet obliquity of β Pictoris b” showing that if upcoming JWST observations confirm a suspected obliquity then there may be a massive exomoon to detect! Keep calm and carry on observing…. 🔭🪐 #astrodon

A cartoon of the orbits of the exoplanets Beta Pic b and c around the central star, with a zoom in of Beta Pic b showing the geometry of the spin axis of the planet with respect to the orbital plane of an exomoon orbiting around it. We Like The Mooooooon!
