Query: Change in the Orbital Period of a Binary System Due to Dynamical Tides
  for Main-Sequence Stars   We investigate the change in the orbital period of a binary system due to
dynamical tides by taking into account the evolution of a main-sequence star.
Three stars with masses of one, one and a half, and two solar masses are
considered. A star of one solar mass at lifetimes $t=4.57\times10^9$ yr closely
corresponds to our Sun. We show that a planet of one Jupiter mass revolving
around a star of one solar mass will fall onto the star in the main-sequence
lifetime of the star due to dynamical tides if the initial orbital period of
the planet is less than $P_{\rm orb}\approx2.8$ days. Planets of one Jupiter
mass with an orbital period$P_{\rm orb}\approx2$ days or shorter will fall onto
a star of one and a half and two solar masses in the mainsequence lifetime of
the star.
