TOI-1468 b Archives

Emission spectra for different atmospheric scenarios. The curves show the planetary flux to stellar flux ratio in ppm as a function of wavelength in µm. In all cases we considered a surface albedo of 0.1, heat redistribution factor based on Koll (2022) and colour-coded in the legend, ordered by the corresponding location of the model in the 15 µm bandpass. Only the no atmosphere cases have an albedo of 0 and 0.1 and zero heat redistribution. The grey dashed line and the shaded area is the blackbody emission at 1024 K and 1σ confidence interval. The black dot is the measured joint occultation depth with its 1σ uncertainty, while the pink diamond is the measured value from the independent analysis using Frida. The blue curve and light blue shaded area at the bottom is the response function of the F1500W filter. -- astro-ph.EP

Terrestrial exoplanets orbiting nearby small, cool stars known as M dwarfs are well suited for atmospheric characterisation. Given the strong XUV irradiation from M dwarf host stars, orbiting exoplanets are […]
