Is there another massive exoplanet in the Beta Pic system? Lacquement+ on “Dynamics of the Beta Pictoris planetary system and possibility of an additional planet” show that the two known planets cannot sculpt the current circumstellar disk, but an additional one (or two) planets can! #astrodon 🔭🪐

Two fuzzy grey circles represent the simulation of the disk around beta pictoris. Two small circles indicete the known exoplanets, and two additional larger circles the orbits of two hypothetical planets. The other figure shows the position of the four planets and the inner edge of the disk that is sculpted by them.
