Magnetic Field of Gas Giant Exoplanets and Its Influence on the Retention of Their Exomoons
The Astrophysical JournalWe study the magnetic and tidal interactions of a gas-giant exoplanet with its host star and with its exomoons, and focus on their retention. We briefly revisit the scaling law for planetary dynamo in terms of its mass, radius, and luminosity.

Searching for star-planet interactions within the magnetosphere of HD189733
, 2010 International audienceHD189733 is a K2 dwarf, orbited by a giant planet at 8.8 stellar radii. In order to study magnetospheric interactions between the star and the planet, we explore the large-scale magnetic field and activity of the host ...

Investigating the Low‐Temperature Phase Stability of the Binary Ta–W System
Advanced Engineering Materials, EarlyView.Atomistic simulations show that the binary Ta–W system forms ordered intermetallic phases, B2‐TaW and D03‐TaW3, as 0 K ground states. Configurational entropy, however, lowers the free energy of the disordered bcc solid solution, which becomes the stable phase above about 400 K.

Radio Prospects of Extrasolar Aurorae Polaris as a Probe of Planetary Magnetism
The Astrophysical JournalMagnetized exoplanets are expected to emit auroral cyclotron radiation in the radio regime due to the interactions between their magnetospheres, the interplanetary magnetic field, and the stellar wind.

Magnetic inclination e ects in star-planet magnetic interactions [PDF]
, 2017 A large fraction of the exoplanets discovered today are in a close-in orbit around their host star. This proximity allows them to be magnetically connected to their host, which lead to e cient energy and angular momentum exchanges between the star and ...

Advanced Engineering Materials, EarlyView.To enhance through‐thickness conductivity without sacrificing impregnation, large spherical graphite particles are intentionally employed in a low‐viscosity resin. Unlike finer conductive fillers, these particles remain outside the fiber bundles and accumulate in resin‐rich interlaminar regions during molding.

Tilted Circumbinary Planetary Systems as Efficient Progenitors of Free-floating Planets
The Astrophysical Journal LettersThe dominant mechanism for generating free-floating planets has so far remained elusive. One suggested mechanism is that planets are ejected from planetary systems due to planet–planet interactions.

Disentangling Bulk and Surface Contributions to Charge and Discharge Fading in High‐Voltage LiCoO2
Advanced Functional Materials, EarlyView.High‐voltage operation of LiCoO2 accelerates capacity fading through bulk and surface degradation. By introducing a LiTaO3 coating to selectively suppress surface degradation, bulk and surface contributions to charge and discharge fading are decoupled.

Chitin‐Derived Carbon‐Metal Functional Materials
Advanced Functional Materials, EarlyView.Functional carbon materials are synthesized from combination of biopolymer (chitin) and iron precursors. The resultant material exhibits superior surface area and adsorptive properties compared to carbon materials synthesized directly from pure chitin.

Planet–star plasma interactions
, 2008 Planet–star plasma interactions can be described as the interaction of a plasma flow with an obstacle, each being possibly magnetized. Examples of the 4 possible situations are found in our solar system, with intense radio emissions produced in 3 ...
