1. Revealing the Spatial Distribution of Dust and Plasma Solitary Waves in Jupiter's Innermost Magnetosphere Using Juno Waves Observations astro-ph.EP · 14 Oct · 1 hit

   Jupiter's faint ring system contains micron- and submicron-sized dust whose dynamics are influenced by the planet's rapidly rotating magnetic field. Optical observations have established the morphology of the main…

2. Probing Planet Formation within 10 au: Dust Substructures in Extremely Compact Protoplanetary Disks astro-ph.EP · 14 Oct · 3 hits

   …a still substantial $\sim$50% between 3 and 30 au, with the lower rate likely affected by optical depth. The planet masses required to open gaps within 5 au fall in the super-Earth to mini-Neptune regime. These results…

3. HD 152384: A 5 Myr old debris disk system showing a gaseous ring of refractory elements at the dust sublimation radius astro-ph.SR · 14 Oct · 1 hit

   Context: Circumstellar gas around young stars provides key insights into planet formation and disk evolution. HD 152384, a young (5 Myr) A0 V star in Sco-Cen, shows hybrid-disk…

4. ExoEcho: Exoplanet Ephemerides Change Observations. III. A JWST Survey for Transit Timing Variations of 37 Exoplanets astro-ph.EP · 14 Oct · 2 hits

   …observations and analyze 84 light curves of 37 exoplanets, including 20 hot Jupiters, 11 Neptune-like planets, and 6 super-Earths. We derive updated transit ephemerides and conduct a systematic search for…

5. The Limits of Tidal Circularization and Atmospheric Escape for Mini-Neptunes and Super-Earths: The Case of TOI-2257 b astro-ph.EP · 13 Oct · 3 hits

   …because their radii are large enough to generate significant torques. In the super-Earth scenario, the planet could lose $\sim$10 Earth ocean masses of surface water during the $\sim$75 Myr pre-main sequence and…

6. Chandra-JWST Probing the Effects of Moderate X-Ray Superflares on Protoplanetary Disks astro-ph.SR · 13 Oct · 2 hits

   Powerful X-ray flares from young stars may rapidly alter the physical and chemical conditions of their planet-forming disks, but direct observational tests remain scarce. We present a Chandra-JWST/NIRSpec study…

7. Science-Driven Performance Requirements for UV Coronagraph Design: Implications for O$_3$ Detection in Earth-like Atmospheres astro-ph.EP · 13 Oct · 1 hit

   …from sulfur dioxide (\ce{SO2}). Our analysis demonstrates the \ce{O3} abundances for Proterozoic Earth-like planets with \ce{O2} as low as 0.1\% the present atmospheric level, can be constrained to within an order of…

8. Thermodynamically consistent equation of state tables for use in giant planet and brown dwarf interior modeling astro-ph.EP · 13 Oct · 5 hits

   Equation of state (EOS) tables used in giant planet modeling exhibit regions of strong thermodynamic inconsistency, or disobedience to the first law of…
