A historical summary of stellar-perturbation analyses is presented, followed by a discussion of the attainable accuracy and the sources of observational errors. A provisional value for the mass-density of astrometric companions is found to be 0.063±0.018 (p.e.) solar masses per cubic parsec.

Resumen

Resumen

Se presenta un resumen histórico de los análisis de perturbaciones estelares y en seguida, una discusión de la precisión alcanzable y las fuentes de los errores observacionales. Se ha encontrado un valor provisional para la densidad de masa de las compañeras astrométricas : 0.063±0.018 (e.p.) masas solares por parsec cúbico.
