Climate hypersensitivity to solar forcing? [PDF]
Annales Geophysicae, 2000 We compare the equilibrium climate responses of a quasi-dynamical energy balance model to radiative forcing by equivalent changes in CO2, solar total irradiance (Stot) and solar UV (SUV).

Interesting Features in the Combined GALEX and Sloan Color Diagrams of Solar-like Galactic Populations [PDF]
, 2014 We report on intriguing photometric properties of Galactic stars observed in the GALEX satellite's far-UV and near-UV bandbasses as well as from the SDSS survey and the Kepler Input Catalog. First, the FUV-NUV color distribution of stars in the Kepler field consists of 2 distinct peaks.

Photo‐Assisted Zn‐Iodine Battery via Bifunctional Cathode with Iodine Host and Solar Response Boost
Advanced Functional Materials, EarlyView.A bifunctional cathode based on BiOI materials is developed for photo‐assisted Zn‐iodine batteries, serving as both an iodine host and a solar‐responsive material. This design enables dual reaction routes involving vacancy‐based iodine storage and reversible two steps iodine redox.

Characteristics of solar UV irradiance
Meteorologische Zeitschrift, 1994 Solar UVB irradiance is measured worldwide with the Robertson-Berger sunburn meter whose spectral sensitivity is adapted to the action spectrum of human erythema. Thus, the Robertson-Berger sunburn meter measures the erythemal effective irradiance.

CO Cameron band and CO2+ UV doublet emissions in the dayglow of Venus: Role of CO in the Cameron band production [PDF]
, 2013 Present study deals with the model calculations of CO Cameron band and CO2+ ultraviolet doublet emissions in the dayglow of Venus. The overhead and limb intensities of CO Cameron band and CO2+ UV doublet emissions are calculated for low, moderate, and high solar activity conditions. Using updated cross sections, the impact of dierent e-CO cross section

UV bright red-sequence galaxies: a comparative study between UV upturn and UV weak systems [PDF]
, 2020 Ultraviolet (UV) emission from galaxies is associated with hot components, whether from stellar sources or not. By making use of colour-colour diagrams, early-type galaxies (ETGs) can be classified in terms of their UV emission in mainly three categories: residual star-formation, UV weak, and UV upturn.

Finding the best proxies for the solar UV irradiance [PDF]
Geophysical Research Letters, 2009 Solar UV emission has a profound impact on the upper terrestrial atmosphere. Because of instrumental constraints, however, solar proxies often need to be used as substitutes for the solar spectral variability. Finding proxies that properly reproduce specific spectral bands or lines is an ongoing problem. Using daily observations from 2003 to 2008 and a
