The disk transport rates range up to 1e - 7 solar mass per year and scales with planet mass to the power of 3/2.
They developed the model to report how the total number of planets (detected or not) is dependent on planet mass and orbital distance.
Multiple planets transiting the same star reveal more: period ratios determine stability and dynamics, mutual gravitational interactions reflect planet masses and orbital shapes, and the fraction of transiting planets obs... ▽ More When an extrasolar planet passes in front of its star (transits), its radius can be measured from the decrease in starlight and its orbital period from the time between transits.
By surveying the whole sky, we will find systems that orbit stars 10 times closer and 100 times brighter than those found by Kepler — opening up new possibilities for measuring planet masses and densities, studying their atmospheres, characterizing their host stars, and establishing the full nature of the systems in which the planets reside.
The power law model population is dependent on four key parameters: How fast the number of planets changes with planet mass, how fast the number of planets changes with orbital distance, the outer-most orbital distance at which a planet can be detected, and the combination of mass and orbital distance that produces the most planets (the «pivot point»).
Multiple planets transiting the same star reveal more: period ratios determine stability and dynamics, mutual gravitational interactions reflect planet masses and orbital shapes, and the fraction of transiting planets observed as multiples has implications for the planarity of planetary systems.
The planet mass (derived mostly from the radial velocity data) is comparable, 3.47 ± 0.15 Jupiter masses in the KELT paper, and 3.69 ± 0.18 in ours.
Studying the archi - tectures of these systems, measuring planet masses and radii, and observing these planets» atmospheres during transit directly informs theories of planet assembly, migration, and evolution.
Continued Kepler observations will dramatically improve the constraints on the planet masses and orbits and provide sensitivity for detecting additional non-transiting planets.
We estimate the planet mass and radius to be 24.5 + / - 3.8 Earth masses and 3.99 + / - 0.21 Earth radii.
