Description

Contemporary studies of exoplanet habitability often use white-light measurements to estimate the ultraviolet (UV) effects of stellar flares, often by assuming a 9000K blackbody for the bolometric flare spectrum. We have combined TESS and archival GALEX photometry to test the UV predictions of white-light flare rates using the 9000K model and discuss the background and our methodology in this poster. We have found from our preliminary results that the UV predictions of white-light flare rates do not accurately reflect the NUV or FUV flaring activity of low-mass stars and are working to quantify the scale of this disconnect.
