Earth as an Exoplanet. III. Using Empirical Thermal Emission Spectra as an Input for Atmospheric Retrieval of an Earth-twin Exoplanet

open access: yesThe Astrophysical Journal
In this study, we treat Earth as an exoplanet and investigate our home planet by means of a potential future mid-infrared space mission called the Large Interferometer For Exoplanets (LIFE).

Uni‐Axial Densification of Slurry‐Casted Li₆PS₅Cl Tapes: The Role of Particle Size Distribution and Densification Pressure

open access: yesAdvanced Materials, EarlyView.
Solid‐state batteries promise high energy density and safety for electric vehicles. This study examines the densification of slurry‐casted Li₆PS₅Cl separator tapes, highlighting the role of particle size distribution and uni‐axial pressure. Wet milling refines particles while preserving conductivity, and a critical compaction threshold leads to ...

Minor planet 1566 Icarus: Asteroid or comet? [PDF]

open access: yes
By employing a cometary nongravitational force model, based on the outgassing of a water ice nucleus, the orbital fits to the optical and radar astrometric data are improved for both Apollo and Icarus.

Disc-planet interactions in sub-keplerian discs

open access: yes, 2009
One class of protoplanetary disc models, the X-wind model, predicts strongly subkeplerian orbital gas velocities, a configuration that can be sustained by magnetic tension.

The PTF Orion Project: a Possible Planet Transiting a T-Tauri Star [PDF]

open access: yes, 2012
We report observations of a possible young transiting planet orbiting a previously known weak-lined T-Tauri star in the 7-10 Myr old Orion-OB1a/25-Ori region. The candidate was found as part of the Palomar Transient Factory (PTF) Orion project.

Molecular Fragmentation of Acetylene by VUV Double Photoionization

open access: yesProceedings, 2017
Acetylene is a simple molecule of interest for interstellar medium (ISM) and planetary atmospheres. The presence of C2H2 was detected by IR spectroscopic measurements. Acetylene was also found as a minor component in the atmosphere of gas giants like the

Disordered Rocksalts as High‐Energy and Earth‐Abundant Li‐Ion Cathodes

open access: yesAdvanced Materials, EarlyView.
Disordered rocksalts with lithium excess (DRX) offer a new direction in Li‐ion cathode design beyond conventional Ni‐ and Co‐based materials. This review highlights the design principles, synthesis strategies, and performance optimization of DRX oxides and oxyfluorides for energy‐dense, sustainable batteries using Earth‐abundant transition metals and ...

Kepler-432: a red giant interacting with one of its two long period giant planets [PDF]

open access: yes, 2015
We report the discovery of Kepler-432b, a giant planet ($M_b = 5.41^{+0.32}_{-0.18} M_{\rm Jup}, R_b = 1.145^{+0.036}_{-0.039} R_{\rm Jup}$) transiting an evolved star $(M_\star = 1.32^{+0.10}_{-0.07} M_\odot, R_\star = 4.06^{+0.12}_{-0.08} R_\odot ...

Bimodal Spin Switch Emerging from Hybridized 2D MoS2/Ferromagnet Interfaces

open access: yesAdvanced Materials, EarlyView.
This study demonstrates a novel integration of 2D semiconductors with ferromagnets using pulsed laser deposition, revealing hybridization‐driven spin manipulation. Vertical spin valves with MoS2 and Ni(111) show exotic bimodal spin signals and strong deviations from Jullière's model. These results highlight the « 2D spinterfaces » key role in unlocking
