Parameters of four multiple systems from
speckle interferometry
Astronomy Letters 25 (1999) 797-801
Abstract.
New or refined visual orbital elements are presented for four double
stars
(HR 266 AP, 88 Tau AP=CHARA 18, Ori AB=McA 18, ADS 16904 AP=CHARA 149)
that
are members of multiple systems. Relative photometry and positional
speckle
measurements with the 6-m telescope and published
radial-velocity data for the stars are used. Photometric data and
parallaxes
from the Hipparcos catalogs are also taken into account. New physical
models
are proposed for multiple systems.
