Thermal Emission and Confirmation of the Frigid White Dwarf Exoplanet WD 1856+534b - Astrobiology
We report the detection of thermal emission from and confirm the planetary nature of WD 1856+534b, the first transiting planet known to orbit a white dwarf star. Observations with JWST’s Mid-Infrared Instrument (MIRI) reveal excess mid-infrared emission from the white dwarf, consistent with a closely-orbiting Jupiter-sized planet with a temperature of 186+6−7 K. We attribute […] The post Thermal Emission and Confirmation of the Frigid White Dwar…
