Abstract

The result of a survey of H-alpha emission objects in an area of approximately 25 square degrees centered on the star CD -24°12765 (R.A.=16h38.m5; Dec.=-24°22';1950), is presented. Only 33% of H-alpha emission stars discovered by Dolidze and Arakelyan (1959) which are located in  the present survey region, are redetected in our plates. A total number of 32 new H-alpha emission objects are found. Their position and finding charts are given.

Abstract

Tudjuh puluh delapan buah bintang Hα-emisi jang baru dan dua buah kabut-planit telah diketemukan pada suatu survey dalam daerah kabut gelap dan bertjahaja pada lingkungan bintang m Cen. Pusat daerah ini terletak pada Î±=13h04m; δ=-63°30'(1875). Posisi kira-kira magnitudo V dan warna V-R telah ditentukan. Peta-peta jang menundjukkan letak benda-benda itu dilampirkan.Di antara bintang-bintang emisi ternjata ada 12 buah jang mungkin merupakan bintang berubah. Hal ini menjokong kesimpulan bahwa sebagian daripada bintang emisi jang lemah tjahajanya mungkin membentuk asosiasi-asosiasi T jang mempunjai hubungan dengan kabut-kabut  tersebut di atas dan mungkin djuga mempunyai hubungan dengan asosiasi OB jang dinamakan I-Cru.
