    On the Component Masses of Visual Binaries by Ninkovic, S., Cvetkovic, Z.

    Published 2010-06-01
    “…Their total masses were obtained dynamically, i.e. they were calculated using the orbital elements and the new Hipparcos parallaxes. For the same pairs the total mass was also found astrophysically - by applying the mass-luminosity relation. …”

    The abundance of brown dwarfs by Binney, J

    Published 1998
    “…If these power-law mass functions are truncated at 0.001Msun, the contribution to the local density of stars lies between 0.016 and 0.039 Msun pc^-3, in conformity with the density measured dynamically from Hipparcos stars. If the mass function is generalized from a power law to a low-order polynomial in log(M), the mass in stars with M&lt;0.1Msun is either negligible or strongly divergent, depending on the order of the polynomial adopted.…”
