Recent work has shown that the planets in the $Kepler$ Mission's population of multi-transiting systems show surprising uniformity in both mass and radius. In this brief note, I show that this intra-system mass uniformity extends to multiple-planet systems detected with the Doppler velocity technique, thereby avoiding possible biases associated with masses determined by transit timing. I also show that intra-system mass uniformity breaks down when a system contains one or more giant planets.

  1. Warm Sub-Saturns Orbiting Single Stars Are Spin-Orbit Aligned

    astro-ph.EP 2026-07 conditional novelty 6.0

    Warm sub-Saturns around single cool stars are predominantly aligned whereas hot sub-Saturns are frequently misaligned (3.2σ), a separation-dependent transition the authors attribute to high-eccentricity migration.

  2. Tidal evolution of packed moon systems around an Earth-mass planet

    astro-ph.EP 2026-07 conditional novelty 5.0

    Including tidal migration cuts the maximum stable moon count around an Earth-mass planet to about two Moon-sized, three Pluto-sized, or five Ceres-sized moons, confined to narrow orbital-spacing windows.
