Thermal Emission and Confirmation of the Frigid White Dwarf Exoplanet WD 1856+534 b

Thermal Emission and Confirmation of the Frigid White Dwarf Exoplanet WD 1856+534 b

We report the detection of thermal emission from and confirm the planetary nature of WD 1856+534 b, the first transiting planet known to orbit a white dwarf (WD) star. Observations with JWST’s Mid-Infrared Instrument reveal excess mid-infrared emission from the WD, consistent with a closely orbiting...
