Reply to comment by PlaidBastard in Is the percentage of mass in the parent star, comparable between different systems? by bizzehdee

There's one big caveat to add on to this as well: a lot of current conjecture is that more stars are in multi-star systems than not. //Don't have a reputable source for this, am armchair at best with any of this.

I don't know how widely accepted it is that more stars are in binaries+ than not; regardless, in those systems you'd have a large variation in planetary creation and a non-trivial percentage mass in the partner star.

Oh, yeah, it's actually pretty widely agreed that most stars are in multiple systems, although I have no idea how many of those are on the scale of thousands or more AUs. Close-in binaries and trinaries churn everything up in such a way as to ensure planet formation doesn't really happen, according to lots of simulations and some pretty solid first principles physics justifying all of that.
