Moving underset text closer to main text

Moving underset text closer to main text

I have an arrow with some text directly underneath, using the command
\newcommand*{\tautrans}%
  {\underset{\scriptstyle \tau^*}{\longrightarrow}}%
Since \tau^* is not close enough to \longrightarrow, I changed to
\newcommand*{\tautrans}%
  {\underset{\scriptstyle \raisebox{.2em}{\ensuremath{\tau^*}}}{\longrightarrow}}%
Unfortunately, this changes the distance between lines, but not between \tau^* and \longrightarrow.
So how can I move \tau^* a little bit up without moving anything else, so that \tau^* comes closer to \longrightarrow?
