Binary star mass function

WebNov 1, 2024 · The photometric variability period of the giant is consistent with the orbital period, indicating star spots and tidal synchronization. Constraints on the giant’s mass and radius imply that the unseen companion is 3.3 + 2.8 − 0.7 solar masses, indicating that it is a noninteracting low-mass black hole or an unexpectedly massive neutron star ... WebAssuming all binary and higher-order stellar systems can be resolved into individual stars in some population such as the solar neighborhood and that only main-sequence stars are selected for, then the number of stars per cubic parsec (pc 3) in the mass interval m tom+dm is dN = Ξ(m)dm, where Ξ(m) is the observed present-day mass function (PDMF).
