Catalog Service: ADS 9731: a new sextuple system
Description
Observations with the correlation radial velocity meter of ADS 9731 were carried out during 1996-1997. We established that the components A and D of the visual quadruple system ADS 9731 are spectroscopic binaries with periods of 3.87 and 14.3 days, respectively. Their orbits are computed. New photometry has demonstrated the absence of eclipses in the close pair Aab. The spectral types and luminosities of all six components matching the are found.
