Unfolding the ramps that will guide the ExoMars Rosalind Franklin rover onto the martian surface requires a few engineering tricks. This close-up image of the hinge shows a part of the mechanism that will swing the ramps open on the Red Planet. -- CREDIT Astronika, ESA (Larger image )

Homöller plots of the time- and horizontal-mean vertical profiles of equivalent potential temperature (colors) in each constant-𝛽 simulation. Values from within the model sponge layer are not shown. The black vertical line denotes the start of the 20-day steady-state period that we analyze for each simulation. -- eartharxiv.org

Simulated stellar wind of TOI-1860, DS Tuc A, and HD 63433 in the x⋆ −y⋆ plane. The rotation axis lies along the positive z⋆. The Alfvén surface is shown as a translucent surface and its intersection on the x⋆ −y⋆ plane is shown as a white curve. The colour bar indicates the total wind velocity. The orbits of the hosted exoplanets are also included as coloured ellipses. For HD 63433, we also show the simulations from the 2023 data analysed in Bellotti et al. (2024). -- astro-ph.SR

Weighted mean abundance differences (large–small planet hosts) as a function of the chosen radius cutoff. Colored curves trace the various composite indices, with shaded bands showing uncertainties. The apparent volatile enhancement should be regarded as tentative given the limited reliability of C and N measurements. -- astro-ph.EP

Simulated light curves for triple-lens systems where at least one planet lies in the resonant regime, as defined by the massratio-dependent boundaries (Equations 7) These configurations generally show strong central caustic perturbations and yield the highest detection efficiencies in our sample. For each case, the two smaller panels show the triple-lens magnification map and the map of the relative difference between the triple- and binary-lens models near the central caustic. -- astro-ph.EP
