Dear PF Forum,
Sorry for asking two questions in a row. Because I think my next question belongs to a new thread. After all it's Sunday here.
My friend told me about Kelt - 4A. Orbitting 3 stars.
So, in this galaxy (and universe) if let alone to the law of gravity and chance.
1: Can there be a system where there's no a single star in it? Every object in the system orbits the most massive object in the middle, where the most massive object mass in only, say 10 Jupiter mass?
2: Can there be a system where all of its "planet" are stars, because all of their mass is higher than the lowest possible star mass?
It's just out of curiousity.
And if those 2 questions are impossible, are there any law that govern that for a system, its orbit center must have at least 1 solar mass.
Such as the law that for the minimum natural black hole is 3 solar mass (Chandrasekar? Paully Exception Principle?)
Or the law that the lowest possible mass for a neutron star (always natural, right ) is 1.4 solar mass
