Discrepancies between isochrone fitting and gyrochronology for exoplanet host stars? [PDF]
, 2014 Using a sample of 68 planet-hosting stars, I carry out a comparison of isochrone fitting and gyrochronology to investigate whether tidal interactions between the stars and their planets are leading to underestimated ages using the latter method. I find a

Contact‐Free Human‐Machine Interfaces via Printed Thermopile Infrared Arrays
Advanced Science, EarlyView.Can a printed sheet locate and sense a fingertip without being touched? Fully printed, flexible thermoelectric arrays convert the infrared from a hovering finger directly into voltage, with no external power. Aerosol‐jet‐printed silver mirrors partially shield each pixel, creating a local temperature gradient.

Rotation, activity, and stellar obliquities in a large uniform sample of Kepler solar analogs
Journal of Space Weather and Space Climate, 2016 In this study, we undertook a deep photometric examination of a narrowly-defined sample of solar analogs in the Kepler field, with the goals of producing a uniform and statistically meaningful sample of such stars, comparing the properties of planet ...

Calculating Vsin(i) of Planet-hosting Young Stars [PDF]
, 2017 Constraining the spin-orbit alignment of close-in planets in young systems can provide insight on their migratory history. We can combine Vsin(i) with measurements of the stellar rotation period and radius to determine the star\u27s orbital inclination ...

Beryllium abundances in stars hosting giant planets
, 2002 We have derived beryllium abundances in a wide sample of stars hosting planets, with spectral types in the range F7V-K0V, aimed at studying in detail the effects of the presence of planets on the structure and evolution of the associated stars ...

Advanced Energy Materials, EarlyView.Boron‐oxide‐assisted particle engineering stabilizes O3‐type layered cathodes for sodium‐ion batteries by mitigating phase transitions and lattice strain. Acting as flux and structural modifier, boron forms submicron hexagonal platelets with (003) facets and expanded Na‐layer spacing, enabling rapid Na⁺ diffusion and mechanical resilience.

No Signature of the Birth Environment of Exoplanets from Their Host Stars’ Mahalanobis Phase Space
The Astrophysical JournalThe architectures of extrasolar planetary systems often deviate considerably from the “standard” model for planet formation, which is largely based on our own solar system.
