Diffuse Ionized Gas in the beta CMa Tunnel

Gry, C.; Dupin, O.

We present HST observations of the interstellar medium toward the star beta CMa known to be located in a low density extension of the Local Bubble. Most of the matter in the sight-line is ionized and clumped in two main components. One of them, as well as one of the components detected toward epsilon CMa, is mostly ionized and only slightly deplet…
