| Abstract: |
We report on a possible correlation between the masses and periods of the extrasolar planets, manifested as a paucity of massive planets with short orbital periods. Monte-Carlo simulations show that the effect is significant at a confidence level of 99.992%. Additionally, we show that planets found in binary stellar systems may have an opposite correlation. The different trend in the population of planets in binaries is shown to be statistically significant, in spite of the small number of planets in binaries. In the context of disk-driven migration, the paucity of massive planets with short periods may be explained by the gap opened in the disk by very massive planets, which prevents them from migrating far enough to populate the close-in orbits. |
