Sketch showing the interaction of ultraviolet light with the different layers of a planet's atmosphere. The ultraviolet spectrum of a star drives photochemical reactions (FUV and NUV photons, 100-320 nm) and atmospheric escape (EUV photons, 10-90 nm) of the orbiting planet. The EUV spectrum is calculated from chromospheric and coronal lines of the FUV spectrum, while the 100-115 nm band provides a unique diagnostic of temperature and abundances. The spectrum of the host star is used to predict the most promising habitable planet candidates and to interpret the atmospheric spectrum. — astro-ph.IM
Here we present the current status of promising ultraviolet technologies in preparation for the Habitable Worlds Observatory.
Working with experts representing the numerous groups working in the ultraviolet field, we summarize some of the key scientific drivers, present the debate around the 100 Angstrom blue wavelength cutoff, and summarize the current status of UV technology.
We present the latest technology in contamination control, a vital part of UV equipment planning.
We explore next steps for each technology and provide a path forward with system-level testing and development.
