How to show * as superscript in a formula ?

I am using libreoffice 4.4.5.2. I was writing a document and had to insert a formula. In the formula I had to show w* for complex conjugate of. I wrote the command
w^{*}
in the formula editor, but unfortunately it did not worked (it took it as multilication). So please someone give me a command to represent the asterisks or * as superscript.

Thank you

You can use the asterix as character: w^"*"

‘(U+002A) Asterix’ is the standard character used to indicate multiplication. However, there are quite a few homologues, and I bet that one of the following will work:

  • *(U+002A) ASTERIX
  • ٭(U+066D) ARABIC FIVE POINTED STAR
  • ⁎(U+204E) LOW ASTERIX
  • ∗(U+2217) ASTERIX OPERATOR
  • ⚹(U+26B9) SEXTILE
  • ✱(U+2731) HEAVY ASTERIX
  • ﹡(U+FE61) SMALL ASTERIX
  • *(U+FF0A) FULLWIDTH ASTERIX

And then, because I like showing off, there is:-

  • ℂ(U+2102) DOUBLE-STRUCK CAPITAL C (the set of complex numbers)
  • ⊹(U+22B9) HERMITIAN CONJUGATE MATRIX

PS
I found ٭(U+066D) to be ridiculously difficult to delete. Neither [Delete] (U+007F) DELETE nor [←] (U+0008) BACKSPACE would remove it. Only selection+[Delete] did it.

If this helps then please tick the answer (:heavy_check_mark:)

Well that’s natural. That character is “ARABIC FIVE POINTED STAR” (as correctly mentioned in the answer); it uses RTL script. As such, it needs “reversed” (from LTR point of view) handling: Del removes it when cursor is to the right of it, and Backspace works for it when cursor is to the left of it.

{{}*{}} also works

I think the accepted answer (^ " * ") will have the * too far and too small.
and the answer with {{}*{}} resulting * that seems too big, it is more like multiplication.
In order to get the result that i think is compatible with other math (for example with your plot),
I found that this seems to be the best, for example, ^%Ux2217.
but in my case i have to add the symbol to the list first, using the method here.
