Many stars harbour multi-planet systems. As these stars expand late in their evolution, the innermost planet may be engulfed, leading to a common envelope (CE) event. Even if this CE interaction is insufficient to eject the envelope, it may cause the star to expand further, leading to additional CE events, with the last one unbinding what remains of the envelope. This multi-planet CE scenario may have broad implications for stellar and planetary evolution across a range of systems. We develop a…
