I led a paper on “Upper limits on exosatellites around Beta Pictoris b” where we searched for exomoons/satellites around the closest known directly imaged exoplanet. We combined CRIRES+ radial velocity and astrometry showing nothing >150 Earth mass in the Hill sphere #astrodon #exoplanets 🔭 /1

A plot showing the Hill sphere around Beta Pictoris b, and two diagonal lines representing upper limits on detections by radial valocity (sensitive at small orbital periods) and astrometry (sensitive at long orbital periods).
