Multi-Cycle HST Treasury Program for STIS: Mapping the Galactic Environment of the Sun
Abstract
Description
Interstellar clouds form the cosmic "ecosystem" through which the Sun moves. Understanding the physical properties of nearby interstellar material, in sufficient detail to evaluate historical variations in the solar galactic environment, requires a survey of ultraviolet interstellar absorption lines towards stars within 20 pc with the STIS spectrometer. A complete survey would yield ionization, temperature, density and velocity for nearby interstellar clouds, and would require a large number of Hubble Space Telescope orbits spaced over several cycles. This note was submitted as a "white paper" to the Space Telescope Science Institute in support of multi-cycle treasury programs.
This note was submitted Nov. 30, 2007 to the Space Telescope Science Institute in response to a solicitation for white papers commenting on the possibility of instituting multi-cycle treasury programs
