A study of Kapteyns star

Kotoneva, E; Innanen, K; Dawson, P C; Wood, Peter R; De Robertis, M M

Description

We present a review of the current knowledge of Kapteyn's Star (KS) - a nearby, low-metallicity M-dwarf, with an eccentric and retrograde Galactic orbit. A brief survey of its spectroscopic properties is provided, together with an analysis of its Galactic orbit in a Galaxy model that incorporates resonances. We propose that KS may have once belonged to a dwarf spheroidal galaxy that merged with the Galaxy, and whose present remnant, if it still exists, is a globular cluster similar to ω Cen.
