L98-59d: A Molten Exoplanet with a Sulfur-Rich Atmosphere—Hinting at a New Class of Worlds
To the point
L98-59d, a planet about 35 light-years away around a small red dwarf, appears almost completely molten with a surface near 1,900 C and a molten core, gravity from neighboring planets driving magma waves, a sulfur-rich atmosphere that would smell rotten eggs, and, as Harrison Nicholls notes, a mushy molten surface, with Rihem Akkouche saying Webb data support a molten world and habitable conditions are extremely unlikely.
