Abstract:
We propose to carry out studies on the properties of inter-
stellar dust using TAUVEX. Through the multi-band TAUVEX observations,
particularly with the use of filters optimized for extinction observations of the
2175 Å feature, combined with optical observations and 2MASS archived data,
we can derive the extinction curve from UV to near-IR for stars located in different regions and environments. The extinction curve is a sensitive indicator
of the properties of the interstellar dust and, as such, will allow us to trace the
properties and evolution of the interstellar dust as a function of environment.
