Abstract:
We present spectroscopic and photometric analysis of the quintuple
star HD 86222 with an eclipsing component. Until now three visual
components A, B, and C of this multiple star were known. Four
components in the A/B pair were detected during the examination of the
cross correlation functions obtained from the spectra.
Description:
We used two telescopes to collect spectra of HD 86222. The first data
set was obtained between January and March 2004 and the Coude
spectrograph and the 2m RCC telescope at NAO Rozhen were used. The
spectra, from this observing campaign, covered 200Å region near
Mg Tri(5175Å). Moreover, the continuum was not normalised. We
obtained the second data set in the Borowiec Observatory with the 0.4m
newtonian telescope equiped with the echelle spectrograph.
Observations were made between January 2008 and January 2009. The
collected data covered spectral range 4500-9200Å and the continuum
of the spectra was normalised to 1. The wave length scale was not
corrected to the heliocentric values in the both data sets. The first
11 spectra were listed in Table 1 in our paper. The additional spectra
were not measured because of the strong blending of the CCF peaks.
