Hot Jupiters (HJs), gas giant planets orbiting their host stars with periodson the order of days, commonly occur in the Galaxy, including relativelymassive ($1.6-2.4$ $M_\odot$, i.e., A-type main sequence stars) and evolvedstars. The majority of A-type main sequence stars have stellar binarycompanions, which can strongly affect the dynamical evolution of planets aroundeither star. In this work, we investigate the effects of gravitationalperturbations by a far away stellar companion on the orbital evolution of gasgiant planets orbiting A-type stars, the so-called Eccentric Kozai-Lidov (EKL)mechanism, including the effects of general relativity, post-main sequencestellar evolution, and tides. We find that only $0.15~\%$ of A-type stars willhost HJs during their main sequence lifetime. However, we also find a new classof planets, Temporary Hot Jupiters (THJs), that form during the post-mainsequence lifetime of about $3.7~\%$ of former A-type main sequence stars. TheseTHJs orbit on periods of tens to a hundred days and only exist for a few$100{,}000$ years before they are engulfed, but they reach similar temperaturesas `classical' HJs due to the increased stellar luminosities. THJs' spin-orbitangles will mostly be misaligned. THJ effects on the host stars' evolutioncould also be observable for longer than a few $100{,}000$ years. Overall, wefind that approximately $70~\%$ of all gas giant planets orbiting A-type starswill eventually be destroyed or engulfed by their star, about $25~\%$ duringthe main sequence lifetime, about $45~\%$ during post-main sequence evolution.
