J/A+A/343/806       The trapezium system BD+00 1617               (Munari+ 1999)

Kinematics and binaries in young stellar aggregates. I. The trapezium system BD+00 1617 in Bochum 2 Munari U., Tomasella L. <Astron. Astrophys. 343, 806 (1999)> =1999A&A...343..806M (SIMBAD/NED BibCode)
ADC_Keywords: Binaries, spectroscopic ; Radial velocities ; Spectroscopy Keywords: binaries: spectroscopic - stars: early type - stars: fundamental parameters - stars: kinematics - Galaxy: open clusters and associations: individual: Bochum 2 - stars: individual: BD +00 1617 Description: Internal kinematics, spectroscopic binaries and galactic motion are investigated for the trapezium system BD+00 1617 (which lies at the heart of the young open cluster Bochum 2) by means on 73 high resolution Echelle+CCD spectra secured over the period 1994-98. Two of the three O-type member stars are found to be binaries on close and highly eccentric orbits of 6.8 and 11.0 day period. Tables 2 and 3, that are available only in electronic form, give the journal of the observations and the individual radial velocities.
