[astro-ph.EP] The Habitable Worlds Observatory (HWO) will directly image and characterize planets potentially similar to Earth orbiting nearby stars.
![Representative spectral energy distribution fits for four HWO ExEP target stars: HD 2151 (upper left), HD 3651 A (upper right), HD 4813 (lower left), and HD 10700 (lower right). In each panel, the solid curve represents the best-fitting Pickles (1998) template spectrum, and the filled circles show the broadband photometry with associated uncertainties. Photometric error bars are shown in the y-direction, and filter widths in the x-direction. Fractional residuals between the template flux averaged over each bandpass and the literature photometry are shown in the lower sub-panels. -- [astro-ph.EP]](https://i0.wp.com/astrobiology.com/wp-content/uploads/2026/08/Spectral-Energy.png?resize=1200%2C716&ssl=1)
