Abstract

International audienceWe present medium resolution (R 15 km/s) ultraviolet absorption measurements recorded with the HST-Cosmic Origins Spectrograph towards two post-AGB stars located within the M15 globular cluster. By sampling interstellar gas over the 10.4kpc sight-line we have revealed spectral absorption features associated with the foreground g1 Intermediate Vleocity Cloud (IVC), whose distance lies between 1.8 - 3.8 kpc
