The headstone (https://de.wikipedia.org/wiki/Carl_Friedrich_Gau%C3%9F#/medi...) does not (it does feature the star of David, but I couldn't find any notion that Gauß was jewish).
But there's a statue with that star (https://de.wikipedia.org/wiki/Carl_Friedrich_Gau%C3%9F#/medi...)
Gauß wasn’t jewish and it was a Christian cemetery. The gravestone insinuates the form of a cross and the David star just symbolizes the Old Testament.
