A search for possible stellar members of the α-spiral arm


The proper motions of groups of stars, selected according to magnitude and colour, near (l, b.)=(140°, 0°), were analysed in an attempt to identify possible members of the α-spiral arm defined by Verschuur fromHi observations. Other than late type giants the only objects whose distance corresponded to that of this arm were a small group of reddened early type stars.
