In this paper, we analyze the asymptotic profiles of zero points with respect
to the spatial variable of the solutions to the heat equation in
one-dimensional space. By giving suitable conditions of the initial data, we
prove the existence of a zero point such that the asymptotic behavior is O(t)
as tβ+β and its coefficient is characterized by a zero point of the
bilateral Laplace transform of the initial data. Furthermore, we reveal the
second and third-order asymptotic profiles of the zero point
