Abstract:
The large and small-scale (pc) structure of the Galactic interstellar
medium can be investigated by utilising spectra of early- type stellar
probes of known distances in the same region of the sky. This paper
determines the variation in line strength of CaII at 3933.661Å
as a function of probe separation for a large sample of stars,
including a number of sightlines in the Magellanic Clouds.
FLAMES-GIRAFFE data taken with the Very Large Telescope towards
early-type stars in 3 Galactic and 4 Magellanic open clusters in CaII
are used to obtain the velocity, equivalent width, column density, and
line width of interstellar Galactic calcium for a total of 657 stars,
of which 443 are Magellanic Cloud sightlines. In each cluster there
are between 43 and 111 stars observed. Additionally, FEROS and UVES
CaII K and NaI D spectra of 21 Galactic and 154 Magellanic early-type
stars are presented and combined with data from the literature to
study the calcium column density - parallax relationship.
Description:
The data on which the current paper is based were extracted from the
ESO archive and are FLAMES-GIRAFFE observations towards three open
clusters located in the Milky Way, and two in each of the Large and
Small Magellanic Clouds, plus FEROS and UVES observations towards
stars located in the Magellanic system and Milky Way.
