  • 남십자자리 CD 또는 HD 311884는 남십자자리 방향에 있는 쌍성이다. 이 계의 구성원은 태양질량의 48배인 O형 주계열성과 57배 되는 볼프-레이에별이다. 둘은 가까이 붙어 있어서 질량중심을 6일 3시간마다 한 번 돈다. (ko)
  • CD de la Creu del Sud (CD Crucis) és una estrella variable de magnitud aparent mitjana +10,89. S'hi localitza a la constel·lació de la Creu del Sud a 7 minuts d'arc de la variable BZ Crucis. És membre del cúmul Hogg 15 i s'hi troba aproximadament a 3000 parsecs (9.780 anys llum) del sistema solar. L'estel blau és 57 vegades més massiu que el Sol i el seu acompanyant té una massa de 48 masses solars. Igual que altres estels de Wolf-Rayet, aquesta component del sistema perd massa a raó de 3,0 × 10-5 masses solars per any, mentre que l'estel blau ho fa a un ritme trenta vegades menor. (ca)
