Motivated by the identification of the very close-in extrasolar giant planetOGLE-TR-56b, we explore the implications of its existence on problems of tidaldissipation, planet migration, and atmospheric stability. The small orbit ofOGLE-TR-56b makes the planet an interesting test particle case for tidaldissipation in stellar convection zones. We show that it favors prescriptionsof suppressed convective eddy viscosity. Precise timing of the transits ofOGLE-TR-56b might place interesting constraints on stellar convection theory,if orbital period change is detected in the near future.Comment: 12 pages, 1 figure, submitted to ApJ
