Tidal disruption limits in period-density space for circular orbits (Veras et al. 2014). Vertical dashed lines mark the densities of several secondary bodies spanning a factor of five in bulk density from gas giant planets and rubble-pile asteroids through dense rocky bodies. Red regions of the plot represent regions where only single transit events may be detected in the CHEOPS photometry, nonred regions indicate where several occultations are possible within 24 h of photometry. The curves denote the regions where intact bodies may reside, the middle region marks potentially disrupted bodies, and black denotes bodies that we expect to be tidally disrupted.
