Additive Manufacturing Provides Infinite Possibilities for Self‐Sensing Technology

open access: yesAdvanced Science, Volume 11, Issue 28, July 24, 2024.
Proprioception embedded in biological bodies can be migrated to smart devices, depending on the right configuration of materials and structures in the right place. Additive manufacturing technology can meet this very well, which provides unlimited possibilities for the preparation of self‐sensing intelligent devices.

Coupled Planetary Interior and Tidal Evolution

open access: yesThe Astrophysical Journal
We present a new planetary structure/thermal evolution model, designed for use in problems that couple orbital dynamics with planetary structure. We first benchmark our structural/thermal evolution calculations against the MESA stellar evolution code ...

Constraining stellar tidal quality factors from planet‐induced stellar spin‐up

open access: yesAstronomische Nachrichten, Volume 345, Issue 5, June 2024.
Abstract The dynamical evolution of tight star‐planet systems is influenced by tidal interactions between the star and the planet, as was shown recently. The rate at which spins and orbits in such a system evolve depends on the stellar and planetary tidal dissipation efficiency. Here, we present a method to constrain the modified tidal quality factor Q*

Resonant and Ultra-short-period Planet Systems Are at Opposite Ends of the Exoplanet Age Distribution

open access: yesThe Astronomical Journal
Exoplanet systems are thought to evolve on secular timescales over billions of years. This evolution is impossible to directly observe on human timescales in most individual systems.

Die Suche nach kalten, fremden Welten

open access: yesPhysik in unserer Zeit, Volume 55, Issue 3, Page 140-147, May 2024.
Die meisten der heute bekannten extrasolaren Planeten umkreisen ihren Mutterstern auf engen Umlaufbahnen in weniger als 100 Tagen. Gesteinsplaneten mit größeren Bahnradien sind von herausragender Bedeutung für Theorien der Planetenentstehung. Die Mikrogravitationslinsenmethode bietet eine hervorragende Möglichkeit, solche Planeten zu finden – und das ...

The Radius Cliff is a Waterfall: Explaining Sub-Neptune Exoplanets with Steam Worlds

open access: yesThe Astrophysical Journal
The demographics of Kepler planets provide a key testbed for models of planet formation and evolution, particularly for explaining the radius valley separating super-Earths and sub-Neptunes.

Obliquity Constraints for the Extremely Eccentric Sub-Saturn Kepler-1656 b

open access: yesThe Astrophysical Journal Letters
The orbits of close-in exoplanets provide clues to their formation and evolutionary history. Many close-in exoplanets likely formed far out in their protoplanetary disks and migrated to their current orbits, perhaps via high-eccentricity migration (HEM),
