Neutron star as secondary NOT barycentric with primary

[Straha Yeagar]

How common is having a Neutron Star as a secondary star orbiting say an 0, or a wolf rayet? Not a shared barycentre, but actually orbiting such as this:


WR - NS
O - NS

as opposed to this:

WR
NS

O
NS

It's not very common, but nevertheless it has been observed many times throughout the galaxy - you need an object as a primary star that is far more massive than a neutron star - typically, only an O-type star or a black hole will do.

Search the forum for "ringed neutron star". The only way a neutron star can have rings is if the stellar forge creates it as a "planet", in a planetary orbit. I think there are several dozen ringed neutron stars known.

As Sapyx said,

You basically need something significantly larger in mass than the neutron star such that the orbit doesn't significantly raise the barycentre from the surface of the host star but still be close enough to be considered a planetary orbit. I am not certain what defines this in Elite.

Minimum mass bound for a neutron star is about 1.4 solar masses.

So automatically it means you would look for B or an O class star, Most likely O class?

Id like to find one of these myself to be honest

Here's one:

M PUPPIS 35347

Both B and C are neutron stars. B is in such a tight orbit (10 ls) around A that you run the risk of landing in the jet cone on arrival. Happened to me one jump in and scared the hell out of me.

Yes, I necroed the thread.

Bad necro, that system is not what the OP was looking for.
You got:
BH
NS
NS

Yes, the OP is asking about neutron stars in "planetary" orbits. Neutron stars in planetary orbits are given planet numbers, not star letters.

Do what I suggested three years ago, and run a forum search for "ringed neutron star". Use Google to search the forum for that exact phrase, because the forum's search function is sub-optimal. You'll find threads like this one, for example, where the HD 78344 system is examined. The primary is an O-type star; the seventh "planet" is a ringed neutron star. The neutron star's name is "HD 78344 7", not "HD 78344 B". To steal SpaceMonkeyz' pic:

I'm sure there are plenty of known non-ringed neutron stars in planetary orbits, too. They're just not as easy to find on the forum.
