However, recent numerical simulations suggest that the disk may evolve to a configuration perpendicular to the binary orbit (\"polar alignment\") if the binary is eccentric and the initial disk-binary inclination is sufficiently large. We carry out a theoretical study on the long-term evolution of inclined disks around eccentric binaries, calculating the disk warp profile and dissipative torque acting on the disk.
