VizieR Online Data Catalog: Gaia view of Cygnus OB2 and Carina OB1 associations (Lim+, 2019)

The census of high-mass stars (O-, B-type stars, and Wolf-Rayet stars) in Cyg OB2 and Car OB1 associations is more complete than those of the low-mass star population. Such high-mass stars are brighter than G~16mag, and the Gaia DR2 provides very high-precision astrometric data in that magnitude range (Gaia Collaboration, 2018A&A...616A...1G, Cat. I/345). Therefore, we considered only the high-mass star population of the associations in this study.

For Cyg OB2, a list of high-mass stars compiled by Wright et al. (2015MNRAS.449..741W, Cat. J/MNRAS/449/741) was used. This catalogue contains the spectral types, the stellar parameters, and the photometric data of 167 stars earlier than B5 taken from a number of references (Table 1). For Car OB1, Naze et al. (2011ApJS..194....7N, Cat. J/ApJS/194/7) studied 200 OB stars [70 O-type and 130 B-type, compiled from Skiff (2009yCat....1.2023S, Cat. B/mk)]. In addition, we added 106 OB stars from recent photometric or spectroscopic studies (Hur, Sung & Bessell 2012AJ....143...41H, Cat. J/AJ/143/41; Sota et al. 2014ApJS..211...10S, Cat. III/274; Alexander et al. 2016AJ....152..190A; Damiani et al. 2017A&A...603A..81D, Cat. J/A+A/603/A81); Hanes, McSwain & Povich 2018AJ....155..190H, Cat. J/AJ/155/190). A total of 306 high-mass stars in Car OB1 were included in the final list (Table 2).
