For a given peak intensity of radiation of a star that occurs at a wavelength of 2 nanometers, this is located at the spectral band of an X-ray. An X-ray's wavelength typically goes from 0.1 nano meters to 10 nano meters. Given that, the wavelength of the star fits perfectly into the range of an X-ray
