I see sometimes star symbol (*) in the hex editor, like ...00001d0 0000 0000 0000 0000 0000 0000 0000 0000*00001f0 0000 0000 0000 0000 0008 0000 0000 0000...It is probably some sort of separator. However, there are many other separators too. What is the meaning of this star symbol in hex data?

It means that one or more lines were suppressed, because they are identical to the previous line; in this case, it means that the line starting at 00001e0 is all zeroes, same as that starting at 00001d0.To determine the number of deleted lines, you need to look at the addresses involved and the length of each line; in this case, a single line was deleted.If you're using od, this is controlled by the -v flag. By default od will suppress duplicate lines, -v tells it not to.
