We present ultra-high-resolution (0.35 km s−1 FWHM) observations of the interstellar Ca K line towards eight nearby stars (six of which are closer than 30 pc). The spectral resolution is sufficient to resolve the line profiles fully, thereby enabling us to detect hitherto unresolved velocity components, and to obtain accurate measurements of the velocity… CONTINUE READING
