Query: A-type Stars, the Destroyers of Worlds: The lives and deaths of Jupiters
  in evolving stellar binaries   Hot Jupiters (HJs), gas giant planets orbiting their host stars with periods
on the order of days, commonly occur in the Galaxy, including relatively
massive ($1.6-2.4$ $M_\odot$, i.e., A-type main sequence stars) and evolved
stars. The majority of A-type main sequence stars have stellar binary
companions, which can strongly affect the dynamical evolution of planets around
either star. In this work, we investigate the effects of gravitational
perturbations by a far away stellar companion on the orbital evolution of gas
giant planets orbiting A-type stars, the so-called Eccentric Kozai-Lidov (EKL)
mechanism, including the effects of general relativity, post-main sequence
stellar evolution, and tides. We find that only $0.15~\%$ of A-type stars will
host HJs during their main sequence lifetime. However, we also find a new class
of planets, Temporary Hot Jupiters (THJs), that form during the post-main
sequence lifetime of about $3.7~\%$ of former A-type main sequence stars. These
THJs 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 temperatures
as `classical' HJs due to the increased stellar luminosities. THJs' spin-orbit
angles will mostly be misaligned. THJ effects on the host stars' evolution
could also be observable for longer than a few $100{,}000$ years. Overall, we
find that approximately $70~\%$ of all gas giant planets orbiting A-type stars
will eventually be destroyed or engulfed by their star, about $25~\%$ during
the main sequence lifetime, about $45~\%$ during post-main sequence evolution.
