I'm fairly sure any stars are included in the body count: when you start to scan a system the body count never starts at zero, always at the number of stellar objects (plus any planets close enough to the entry point to be scanned automatically).
This is my current system:

The analysis shows:
6 asteroid clusters (not counted) and 13 HMC + 3 rocky bodies = 16
Adding the two stars to the planets gives 18/18 bodies, 6 clusters and one unknown signal.
I haven't been paying attention either.
One thing I haven't come across in the last recent thousand unmapped systems are any Notable Stellar Phenomena.
Edit: @
varonica - I may have misread your post: the
Analysis strip doesn't show stellar bodies; if I got this wrong, apologies.
