Observations Of Exocomets

by Keith CowingMarch 24, 2026March 24, 2026

Input spectra generated with PSG from simulations of modern Earth. The spectra were generated at nine times of day, showing different surface features as the planet rotates (Kofman et al. 2024). A wide diversity in the spectra can be seen, demonstrating the wavelength dependence of the surface features. The black line is an average of all the spectra, representing a longer integration time observation. The data for all of these spectra can be found in the supplementary material. -- astro-ph.EP

Retrieving the Red Edge on Earth-like Planets with Heterogeneous Clouds and Surfaces

Artistic scheme of the VLA 4A/4B binary system, not in scale. Methanol and water absorption features originate from gas located in front of the dust photosphere at 26 µm, which is likely driven by VLA 4B (see text). The photosphere size and location is not certain, but the absorption selectively probes only a layer of sublimated ice, rather than the full bulk envelope, in a location where methanol may desorb more efficiently than water. -- astro-ph.EP

High-resolution mid-IR Spectroscopy of SVS 13-A with EXES/SOFIA: The Surprisingly High CH3OH/H2O Ratio In The Planet-forming Zone Of A Solar Mass Protostar

The left panel shows the relative astrometric orbit of 70 Oph B around 70 Oph A. Red points denote archival visual and micrometric measurements from the WDS/ORB6 catalog, while the solid black curve shows the maximum-likelihood joint orbital solution. 50 orbits color-coded by companion mass are randomly drawn from the posterior and plotted, but they are indistinguishable from the black curve because of the tight constraint on the orbit. The dashed line marks the line of nodes, and the star indicates the primary’s position. The right panel shows the RV variation of 70 Oph A measured by eight instruments. Colors correspond to individual RV datasets as indicated in the legend. Residuals relative to the best-fit model are shown. -- astro-ph.EP

The network of important reactions for the carbon, sulfur, and coupled organosulfur chemistry in the atmosphere of K2-18b. Pathway B (following R. Hu et al. (2025)) dominates the DMS and DMDS production and is highlighted in green. Reaction steps in pathway A (following N. W. Reed et al. (2024)) that are not in pathway B are highlighted in grey. Destruction pathways of DMS and DMDS are highlighted in red. Unimolecular reactions are denoted with dashed lines, bimolecular reactions with solid single lines, and termolecular reactions with solid double lines. -- astro-ph.EP
