Planet formation around stars of various masses: the snow line and the frequency of giant planets

Kennedy, Grant; Kenyon, Scott J


We use a semianalytic circumstellar disk model that considers movement of the snow line through evolution of accretion and the central star to investigate how gas giant frequency changes with stellar mass. The snow line distance changes weakly with stellar mass; thus, giant planets form over a wide range of spectral types. The probability that a given star has at least one gas giant increases linearly with stellar mass from 0.4 to 3 M⊙. Stars more massive than 3 M⊙ evolve quickly to the main...[Show more]
