根据星号的数量及其布局,有三种不同的方法:
\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage{heuristica}
\usepackage{lipsum}
\newcommand{\triast}{\bigskip\par\noindent\parbox{\linewidth}{\centering\large{*}\\[-4pt]{*}\hskip 0.75em{*}}\bigskip\par}%
\newcommand{\threeast}{\bigskip\par\centerline{*\,*\,*}\medskip\par}%
\newcommand{\oneast}{\bigskip\par{\large\centerline{*\medskip}}\par}%
\begin{document}
\lipsum[3]
\oneast
\lipsum[3]
\triast
\lipsum[3]
\threeast
\lipsum[3]
\end{document}
