Which command is used for the \thanks-command star?

Question

I am looking for the command to produce the star which generates the \thanks command used within the \author command in the article class with libertine fonts. Minimal example:

\documentclass{article}
\usepackage[tt=false, type1=true]{libertine}
\usepackage[utf8]{inputenc}
\author{Testauthor$^{*\star\ast}$\thanks{test}}
\title{Testtitle}
\date{}
\begin{document}
\maketitle
\end{document}

Here the relevant part of the pdf:

I am interested in star number four, so the star with five tips. Neither *, nor \star, nor \ast produces it.

Answer 1

You can get this symbol with \textasteriskcentered.

\documentclass{article}
\usepackage[tt=false, type1=true]{libertine}
\usepackage[utf8]{inputenc}
\author{Testauthor\textsuperscript{\textasteriskcentered}\thanks{test}}
\title{Testtitle}
\date{}
\begin{document}
\maketitle

\end{document}
