Many hot Jupiter (HJ) systems have been observed to have their stellar spinaxis misaligned with the planet's orbital angular momentum axis. The origin ofthis spin-orbit misalignment and the formation mechanism of HJs remain poorlyunderstood. A number of recent works have suggested that gravitationalinteractions between host stars, protoplanetary disks, and inclined binarycompanions may tilt the stellar spin axis with respect to the disk's angularangular momentum axis, producing planetary systems with misaligned orbits.These previous works considered idealized disk evolution models and neglectedthe gravitational influence of newly formed planets. In this paper, we explorehow disk photoevaporation and planet formation and migration affect theinclination evolution of planet-star-disk-binary systems. We take into accountplanet-disk interactions and the gravitational spin-orbit coupling between thehost star and the planet. We find that the rapid depletion of the inner diskvia photoevaporation reduces the excitation of stellar obliquities. Dependingon the formation and migration history of HJs, the spin-orbit coupling betweenthe star and the planet may reduces and even completely suppress the excitationof stellar obliquities. Our work constrains the formation/migration history ofHJs. On the other hand, planetary systems with "cold" Jupiters or close-insuper-earths may experience excitation of stellar obliquities in the presenceof distant inclined companions.
