Planets Around Solar Twins/Analogs (PASTA). I. High-precision Stellar Chemical Abundances for 17 Planet-hosting Stars and the Condensation Temperature Trend

The Astrophysical Journal
The Sun is depleted in refractory elements compared to nearby solar twins, which may be linked to the formation of giant or terrestrial planets. Here we present high-resolution, high signal-to-noise spectroscopic data for 17 solar-like stars hosting ...

On The Effect of Giant Planets on the Scattering of Parent Bodies of Iron Meteorite from the Terrestrial Planet Region into the Asteroid Belt: A Concept Study

, 2012
In their model for the origin of the parent bodies of iron meteorites, Bottke et al proposed differentiated planetesimals that were formed in the region of 1-2 AU during the first 1.5 Myr, as the parent bodies, and suggested that these objects and their ...

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

Advanced 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 ...

THE ELEMENTS OF THE BASIC PHOTOMETRICAL CIRCLES ON THE SURFACE OF THE SPHERICAL PLANET AND DETERMINATION OF THEIR PLANETOCENTRIC POSITIONS

Odessa Astronomical Publications, 2016
Formulae for determination of planetocentric positions of the basic photometrical circles on the surface of the spherical planet (the equator of intensity, an orthographic limb and orthographic terminator) from the elements of these circles specified to ...

Modeling Planetary System Formation with N-Body Simulations: Role of Gas Disk and Statistics Comparing to Observations

, 2011
During the late stage of planet formation when Mars-size cores appear, interactions among planetary cores can excite their orbital eccentricities, speed their merges and thus sculpture the final architecture of planet systems.

Transparent, Sprayable Plastic Films for Luminescent Down‐Shifted‐Assisted Plant Growth

Advanced Materials Technologies, Volume 10, Issue 6, March 18, 2025.
Spreading the light: A modular approach to down‐shifting europium‐containing polyoxotitanium luminescent cages is developed, allowing their incorporation into sprayable plastic coatings on agricultural greenhouses for accelerated plant growth. Abstract The world's steadily growing population and global heating due to climate change are a threat to food

The Sovereignty of Sovereignties: On the Satellitization of Planet Earth

L'Espace Politique
The essay explores the emergence of a new paradigm in biopolitical power which is proper to the Anthropocene. Characteristic of this new form of biopower is that it neither exercises direct control over life nor over territory, but rather derives power ...

Toward a Global Classification of Coastal Anthromes

Land, 2017
Given incontrovertible evidence that humans are the most powerful agents of environmental change on the planet, research has begun to acknowledge and integrate human presence and activity into updated descriptions of the world’s biomes as “anthromes ...
