Diagram of TOI-5800 system. The star is shown to scale with the planet’s orbit. — astro-ph.EP Though missions such as Kepler, K2, and TESS have discovered >2,000 sub-Neptune and Neptunian

Peak Δ14C regional response (colour code is shown on the right) over land to the ESPE of 12350 BC (model experiment GW). The central panel depicts the geographical distribution, while

(Top Left) Heatmap of the mean seasonal variations for the very near surface of Europa (x 1 µm) as function of albedo and latitude. (Bottom) Interpolation of the seasonal variations

Keith’s note: this just came out of my head as a stream of inter-related events. Some times I feel like Forrest Gump. Other times I am in Luke Skywalker mode.

Overview of the chemical elements detected in the transmission spectra of Ultra-Hot Jupiters (UHJ). Planets are ordered by decreasing equilibrium temperature. WASP-33 b is a more challenging target due to

The HPF-SpecMatch spectra fit results for order index 5. Top: two plots showing the five best-fit stars (red) selected to compose the spectra. The size and transparency of these five

Displaying the sudden change in spectral features for oxygen-rich atmospheric spectra. Type B atmospheres spectra do not show any CH4 features, as do type C which are extremely oxygen-rich. Both

Phosphorus abundances as a function of fundamental stellar parameters for all sample stars. Upper panel: Phosphorus abundance as a function of Teff. Lower panel: Phosphorus abundance as a function of

Transformations between the ORF (blue), SRF (orange), and BRF (green), with Euler angles. The SRF and the BRF are both rotating frames, with ZS the spin axis of Venus and
