5. Abstract

A cool-star UV spectral catalog---CoolCAT--- will improve dramatically the
accessibility and utility of the rich stellar archive of STIS E140M/H and E230M/H
exposures. CoolCAT will contain digital spectral atlases---echellograms processed to
the same uniform standard, multiple observations graded and coadded, and adjacent
wavelength regions concatenated---and a supporting catalog of line identifications,
wavelengths, widths, and fluxes. Semiautonomous line fitting procedures will ensure
a homogeneous and uniform treatment of the diverse spectral material. Valuable
experience already has been gained with cycle 8 project 8280, which obtained full UV
echelle coverage (1150--3000 Angstrom) of 13 representative late-type stars. My
personal interest in these data involves studies of gas dynamics in stellar outer
atmospheres, traced by emission line Doppler widths and shifts. However, a wide
range of other investigations---from the photochemical evolution of primitive
planetary atmospheres to galactic population synthesis---will be enabled by CoolCAT.
