“…However, only a very small bow shock has been identified in New Horizons data (McComas et al, ). In fact, all results point to an atmosphere much more compact than expected (e.g., Bagenal et al, ; Cravens & Strobel, ; Gladstone et al, ; Hinson et al, ; Krasnopolsky, ; Pérez‐De‐Tejada et al, ; Young et al, ), and that any bow shock would have to be very close to Pluto or even attached to the exobase (Bagenal et al, ; McComas et al, ). More recent simulations, with a compact atmosphere, reproduce the close boundary identified as a bow shock (Feyerabend et al, ; Hale & Paty, ).…”
