3 newly discovered worlds risk dying too close to dying stars

Astronomers have discovered three new exoplanets orbiting dangerously close to their parent stars, on the verge of extinction.

the three outer planets, named TOI-2337b, TOI-4329b and TOI-2669b, were discovered using NASA’s Transiting Exoplanet Survey Satellite (he-goat) and the High Resolution Equation Spectrometer (HIRES) of the WM Keck Observatory in Hawaii.
