Transit light curves and fits for HD 60779 b. The transit models were all fit simultaneously with the RVs, details listed in Table 2. The upper left panel shows the flattened 120 s cadence data from TESS Sector 34. This is the original transit detection. The lower left panel shows the flattened 20 s cadence data from TESS Sector 88. The upper right panel shows the CHEOPS light curve, with the detrending model plotted. The lower right panel shows the detrended CHEOPS transit light curve, fit with the transit model. In all panels, the black points show the data in bins of 0.025 d. -- astro-ph.EP

Absorption spectrum corresponding roughly to the surface Earth gas mixture (N2, H2O and CO2). Here we assume 1 bar of total pressure, including 370 ppm of CO2 and 0.01 bar of H2O at 285 K. The CO2 content corresponds to the Earth’s atmosphere conditions in 2000. -- astro-ph.EP

Mass-radius diagram of the well-characterized small planet population (Mp < 40M⊕,Rp < 4R⊕, mass error better than 25%, radius error better than 8%) from the PlanetS catalogue (Otegi et al. 2020; Parc et al. 2024) (semi-transparent circles), coloured by insolation. TOI-2322 b and c are shown as a pentagon and a hexagon respectively. The composition models of Zeng et al. (2019) are shown by the coloured curves. -- astro-ph.EP

TOI-2322: Two Transiting Rocky Planets Close To The Stellar Rotation Period And Its First Harmonic

Known exoplanets from the NASA Exoplanet Archive in terms of their mass and orbital period. Triangle and circle point markers represent minimum and true masses, respectively. The larger green markers correspond to HD 190360’s three planets. All single-planet systems are made transparent, while all multi-planet systems are connected with a thin black line in order from shortest to longest period. Named period-bins are provided for reference according to rough temperature scales for planets orbiting main sequence FGK stars, and correspond to 0 < P [d] ≤ 1 (ultra-hot), 1 < P [d] ≤ 10 (hot), 10 < P [d] ≤ 100 (warm), 100 < P [d] ≤ 1000 (temperate), 1000 < P [d] ≤ 104 (cold), and 104 < P [d] ≤ 105 (ultra-cold). The gray histograms at the top and right correspond to the underlying distributions of orbital periods and masses. -- astro-ph.EP

Image of a dusty disk around a young star. Among the multiple concentric rings we see a small dot of light (indicated by a white circle). This is an image of a new-born planet, likely a gas giant similar to Jupiter in our own solar system but about 5 times more massive. These observations were taken with the ESO Very Large Telescope in near-infrared light. Credit: C. Ginski/R. van Capelleveen et al.

Observational data on the relative surface temperatures of the Earth and Mars Ts/Ts0 (upper left panel) vs. the theoretical predictions by a few cosmological models at various values of the Hubble parameter normalized to h = 100 km/s/Mpc (dotted curves in three other panels). Solid curves correspond to the standard intergalactic value of the Hubble parameter; and the long-dashed curves, to the original Kˇr´ıˇzek–Somer model [16, 21]. -- astro-ph.EP
