The Dynamical Properties of Stellar Systems in the Galactic Disc K2

We postulate that stars in the Galactic field are born in aggregates of binary stars with half mass radii R 0.5 and number of binaries N bin which are dynamically equivalent to the dominant mode cluster (N bin , R 0.5) ≈ (200, 0.8 pc). Binary orbits are distributed according to an initial period distribution which is consistent with pre-main sequence data… CONTINUE READING
