2 Figure 1. Positions of the major star forming regions of Cepheus, overplotted on a schematic drawing of the constellation. adopted from Yonekura et al. (1997), were defined on the basis of their positions, radial velocities, and distances, where distance data were available. Table 1 lists the dark clouds identified in the Cepheus region from Barnard (1927) to the Tokyo Gakugei University (TGU) Survey (Dobashi et al. 2005), and the molecular clouds, mostly revealed by the millimeter emission by various isotopes of the carbon monoxide (Dobashi et al. 1994; Yonekura et al. 1997). The cloud name in the first column is the LDN (Lynds 1962) name where it exists, otherwise the first appearance of the cloud in the literature. Equatorial (J2000) and Galactic coordinates are listed in columns (2)–(5), and the area of the cloud in square degrees in column (6). Column (7) shows the radial velocity of the cloud with respect to the Local Standard of Rest. The number of associated young stellar objects is given in column (8), and the alternative names, following the system of designations by SIMBAD, are listed in column (9). We
note that the LDN coordinates, derived from visual examination of the POSS plates, may be uncertain in several cases. Figure 3 shows the distribution of the pre-main sequence stars and candidates over the whole Cepheus region. 3 Cepheus Flare Shell 20 Cep OB4 Shell Cepheus Flare clouds 15 NGC 7023 Galactic latitude ( o ) 10 5 Cep OB4 Be 59 S171 Cep OB3 S155 Cep OB2 NGC 7129 Cepheus Bubble NGC 7160 S140 IC 1396 0 Cep OB6 120 115 110 105 100 95 Galactic longitude ( o ) Figure 2. Distribution of the visual extinction in the Cepheus region in the [l,b] plane (Dobashi et al. 2005) with outlines of the major star forming regions, discussed in this chapter, overplotted. Solid rectangles indicate the nominal boundaries of the OB associations (Humphreys 1978; de Zeeuw et al. 1999), and the dashed rectangle shows the Cepheus Flare cloud complex; giant HII regions are marked by solid grey circles, and star symbols indicate young open clusters. Three large circles, drawn by radial dashes, show giant shell-like structures in the interstellar medium. The Cepheus Flare Shell (Olano et al. 2006) belongs to the nearby Cepheus Flare complex, and the Cepheus Bubble (Kun et al. 1987) is associated with the association Cep OB2, and the Cepheus OB4 Shell (Olano et al. 2006) is associated with Cep OB4.
