Abstract
We request the X-ray observations of the two M dwarf flare stars GJ 1243 and CR Dra simultaneously with the HST/COS NUV spectroscopy approved as the HST Treasury program and multi-color optical photometry with TESS and ground-based telescopes. We will investigate the relations among the Neupert/non-Neupert classfications and the optical/NUV spectral properties during flares, which can greatly help to constrain the physics of a unified multi-wavelength stellar flare model. This program provides time-resolved NUV spectra and X-ray flux along with best-fit models on a wider wavelength range from X-ray through red-optical wavelengths. The results will benefit multiple astrophysics communities.
