Galactic structure based on young southern open star clusters.
Abstract
Summary. New observations of 43 southern young open star clusters out to 8 kpc are briefly discussed in relation to galactic structure. The main new results are: (I) extension of the outer arm + II from ...I80o to 2150 and possibly to ; (2) a probable elongation of the local arm (0) out to at least 4 kpc in the direction 1 2450; (3) definition of the Carina Arm out to d 8 kpc. Key words: open star clusters galactic structure
