The Cepheus Flare contains many objects and a large number of dense dark nebulas, or dark clouds, and supernova remnants. 8 major cloud complexes and 208 dark clouds have been identified within the flare, major ones including LDN 1147, LDN 1148, LDN 1152, LDN 1155, LDN 1157, LBN 468, and Barnard 175.[1] It also contains many regions of star formation, including Herbig–Haro (HH) objects, bright patches of nebulosity associated with new born stars.[3] Star formation in the complexes produce various shock fronts, with may account for the wide range of velocities within the Cepheus Flare.[1][2]
The Cepheus cloud has a complex structure with many molecular filaments, low-density cavities, dense areas of gas, expanding shells and other features.[2] There is an infrared loop named GIRL G109+10 that triggers star formation.[4]
The flare has several low-mass star forming centres, but no high-mass star formation regions. As there are five A-type and B-type stars in the Cepheus R2 association, the complex probably had intermediate-mass star formation in the recent past. A list of some of the more notable stars on the Cepheus Flare can be found below.[5]
Other less notable stars in the Cepheus Flare complex include SAO 19953, HD 212826, HD 216486, BD +69°1231, CV Cepheus and BO Cepheus.[5] There have been 98 Young Stellar Objects (YSO) canadites identified.[7] Spatially linked to the Cepheus Flare complex is ASCC 127, a young moving group with around 3,179 identified members that seems to have carved out shells within the flare.[2]
