FAINT OB STARS BEHIND THE COALSACK

FAINT OB STARS BEHIND THE COALSACK

An investigation of OB stars in the Coalsack region is done by means of UBV photographic photometry. The study includes previously known OB stars within a 1° radius circle centered at l = 302̣4, b = — 0.°̣, and newly discovered faint OB stars in five small areas (80 square arc minutes each) within t...

Zusammenfassung:An investigation of OB stars in the Coalsack region is done by means of UBV photographic photometry. The study includes previously known OB stars within a 1° radius circle centered at l = 302̣4, b = — 0.°̣, and newly discovered faint OB stars in five small areas (80 square arc minutes each) within the same circle. Total visual absorption values and minimum distance moduli are derived for all the stars, and the absorption vs. distance modulus diagram is presented. A possible distant OB association is noted in the region sur rounding the compact cluster Hogg 15.
