Non-detection of previously reported transits of HD 97658b with MOST photometry [PDF]

, 2012
The radial velocity-discovered exoplanet HD 97658b was recently announced to transit, with a derived planetary radius of 2.93 \pm 0.28 R_{Earth}. As a transiting super-Earth orbiting a bright star, this planet would make an attractive candidate for ...

Satellite Data Applications for Sustainable Energy Transitions

Frontiers in Sustainability, 2022
Transitioning to a sustainable energy system poses a massive challenge to communities, nations, and the global economy in the next decade and beyond. A growing portfolio of satellite data products is available to support this transition. Satellite data complement other information sources to provide a more complete picture of the global energy system ...

Investigation of Solid‐Solution Phase Formation in AlCuNiSi Medium Entropy Alloys and its Effect on Microstructural, Thermal, and Microhardness Properties

Advanced Engineering Materials, EarlyView.
This study focuses on synthesizing equiatomic AlCuNiSi medium‐entropy alloys using mechanical alloying for advanced industrial applications. Continuous milling leads to grain refinement and the formation of stable BCC/FCC solid‐solution phases, resulting in enhanced mechanical properties. A unique Si‐rich solid‐solution phase is observed, which did not

CHEOPS: A transit photometry mission for ESA's small mission programme

EPJ Web of Conferences, 2013
Ground based radial velocity (RV) searches continue to discover exoplanets below Neptune mass down to Earth mass. Furthermore, ground based transit searches now reach milli-mag photometric precision and can discover Neptune size planets around bright ...

Microlensing Detections of Moons of Exoplanets

, 2008
We investigate the characteristic of microlensing signals of Earth-like moons orbiting ice-giant planets. From this, we find that non-negligible satellite signals occur when the planet-moon separation is similar to or greater than the Einstein radius of ...

A Simulative Approach for the Prediction of Mesoscale Residual Stress Fields in Solution‐Strengthened Ferritic Ductile Iron

Advanced Engineering Materials, EarlyView.
This study presents a 3D representative volume element‐based simulation approach to predict mesoscopic residual stress and strain fields in silicon solid solution‐strengthened ductile cast iron. By modeling phase transformation kinetics with an enhanced Johnson–Mehl–Avrami–Kolmogorov model, the effects of varying cooling rates on residual stresses are ...

The K2 and TESS Synergy. III. Search and Rescue of the Lost Ephemeris for K2's First Planet

The Astronomical Journal
K2-2 b/HIP 116454 b, the first exoplanet discovery by K2 during its Two-Wheeled Concept Engineering Test, is a sub-Neptune (2.5 ± 0.1 R _⊕ , 9.7 ± 1.2 M _⊕ ) orbiting a relatively bright ( K _S = 8.03) K-dwarf star on a 9.1 day period. Unfortunately, due

How to Weigh a Star Using a Moon

, 2010
We show that for a transiting exoplanet accompanied by a moon which also transits, the absolute masses and radii of the star, planet and moon are determinable. For a planet-star system, it is well known that the density of the star is calculable from the
