The Roche limit for close-orbiting planets: Minimum density, composition constraints, and application to the 4.2-hour planet KOI 1843.03

Kavli Affiliate: Alan Levine | First 5 Authors: Saul Rappaport, Roberto Sanchis-Ojeda, Leslie A. Rogers, Alan Levine, Joshua N. Winn | Summary: The requirement that a planet must orbit outside of its Roche limit gives a lower limit on the planet’s mean density. The minimum density depends almost entirely on the orbital period and is […]
