Orbits that make the Box/Peanut X in the Milky Way bar

Our paper on the orbits that make up the X-shape in the Milky Way’s bar by my former undergraduate Caleb Abbott has just been accepted for publication in MNRAS. We show that box orbits and ¬†their resonant cousins make the X-shape. Over 20% of the mass of the bar is associated with the X and most of the orbits (>70%) in the bar contribute to the Box/Peanut/X.
