The destruction of inner planetary systems during high-eccentricity migration of gas giants

open access: yes, 2015
Hot Jupiters are giant planets on orbits a few hundredths of an AU. They do not share their system with low-mass close-in planets, despite these latter being exceedingly common.

Tetrahedral Tilting and Lithium‐Ion Transport in Halide Argyrodites Prepared by Rapid, Microwave‐Assisted Synthesis

open access: yesAdvanced Functional Materials, EarlyView.
This study introduces a rapid, microwave‐assisted synthetic method for halide argyrodite solid‐state electrolytes Li6PS5X${\rm Li}_6 {\rm PS}_5X$ (X=$X =$ Cl−${\rm Cl}^-$, Br−${\rm Br}^-$, I−${\rm I}^-$). Microwave synthesis increases S2−${\rm S}^{2-}$/X−$X^-$ site disorder and rotational disorder of the isolated PS43−${{\mathrm{PS}}_{4}}^{3 ...

Giant planet effects on terrestrial planet formation and system architecture [PDF]

open access: yes, 2018
The giant planets of the solar system likely played a large role in shaping the architecture of the terrestrial planets. Using an updated collision model, we conduct a suite of high resolution N-body integrations to probe the relationship between giant planet mass, and terrestrial planet formation and system architecture.

Search for Low-Mass Exoplanets by Gravitational Microlensing at High Magnification

open access: yes, 2004
Observations of the gravitational microlensing event MOA 2003-BLG-32/OGLE 2003-BLG-219 are presented for which the peak magnification was over 500, the highest yet reported.

Cu‐Based MOF/TiO2 Composite Nanomaterials for Photocatalytic Hydrogen Generation and the Role of Copper

open access: yesAdvanced Functional Materials, EarlyView.
HKUST‐1/TiO2 composite materials show a very high photocatalytic hydrogen evolution rate which increases as a function of the irradiation time until reaching a plateau and even surpasses the performance of the 1%Pt/TiO2 material after three photocatalytic cycles.

On the Love Numbers of an Andrade Planet

open access: yesEarth and Space Science
The Andrade rheological model is often employed to describe the response of solar system or extra‐solar planets to tidal perturbations, especially when their properties are still poorly constrained.

Future Direct Spectroscopic Detection of Hot Jupiters with IGRINS [PDF]

open access: yes, 2013
With about 700 confirmed extrasolar planets, it is time to move beyond discovery and towards characterization. Perhaps the most basic parameter of an extrasolar planet is its mass; however, this is very difficult to determine if the planet does not transit the star. The radial velocity technique, still the most fruitful method of discovering planets in

Optical Control of Ferroelectric Imprint in BiFeO3

open access: yesAdvanced Functional Materials, EarlyView.
Above‐bandgap irradiation at room temperature enables on‐demand optical control of defect‐driven built‐in electric fields in BiFeO₃ thin films, fabricated via scalable, chemical spray pyrolysis. These fields, otherwise “frozen‐in,” can cause severe device degradation, including non‐switchable polarization, dead layers near interfaces, and polarization ...

Survival of Terrestrial Planets in the Presence of Giant Planet Migration

open access: yes, 2003
The presence of ``Hot Jupiters'', Jovian mass planets with very short orbital periods orbiting nearby main sequence stars, has been proposed to be primarily due to the orbital migration of planets formed in orbits initially much further from the parent ...

ECCENTRICITY FROM TRANSIT PHOTOMETRY: SMALL PLANETS IN KEPLER MULTI-PLANET SYSTEMS HAVE LOW ECCENTRICITIES [PDF]

open access: yes, 2015
Solar system planets move on almost circular orbits. In strong contrast, many massive gas giant exoplanets travel on highly elliptical orbits, whereas the shape of the orbits of smaller, more terrestrial, exoplanets remained largely elusive.
