How do you build presently your headers? Do they result from field insertion so that they are automatically set to the current heading? This implies that your headings are styled with Heaging n.
Fields offer several possibilities: complete heading with number and text, number only, text only.
If this is not what you want/need, describe more precisely your goal. I assume this is related to “* *” in your question. If this is the case, I’m thinking of “fake numbering” with “separators”. This may be a solution but needs more consideration if you create a TOC.
Don’t forget to mention OS name, LO version and save format (my first-thought idea will work only in .odt).

Solution
Your star prefix is a “decorator” which is not part of heading significance. Then, don’t type it on every heading. Add it through Tools
>Heading Numbering
In Numbering
tab (for each relevant level), enter your prefix either in Separator Before or After (it does not matter since you have Number None; in case you have a number, play with Before and After to achieve your preferred visual effect).
The prefix is then automatically added whenever you style Heading 1.
You can discard the decorative prefix in the TOC. In the TOC creation or edit dialog, go to Entries
tab and remove the N# descriptor. N#
is a request to insert the heading number with its separators.
