Detection of CaI and CH absorption at the velocity of the variable interstellar component towards κ Velorum.

CRAWFORD I.A.

Abstract (from CDS):

I report the detection of interstellar Cai and CH at the velocity of the previously reported variable absorption component towards κ Velorum (HD 81188). The very high spectral resolution (R ~ 900 000) has resolved the intrinsic line profiles, yielding a kinetic temperature of Tk=190+170–150K, and a line-of-sight tubulent velocity of vt=0.26+0.08–0.13km.s–1, for the densest material. The Cai/Caii ratio implies a spatial density of nH≳103 cm–3, although this may considerably underestimate the density in the variable region itself. The CH column density suggests a path-length of ∼102 to 103 au, supporting suggestions that variable interstellar components such as this are formed in extended structures (sheets or filaments) aligned with the line of sight.
