Infrared spectrum of LHS 3844 b’s hot dayside derived from the brightness contrast to its host star (IMAGE)
Caption
Infrared spectrum of LHS 3844 b’s hot dayside derived from the brightness contrast to its host star in ppm (parts per million = 0.0001%) at different wavelengths. The observational data obtained from the James Webb and Spitzer Space Telescopes (circles and squares) are consistent with mantle (solid orange line) or lava rock (dashed blue line), whereas they rule out an Earth-like crust (dash-dotted green line).
