Analytic orbit propagation for transiting circumbinary planets
, 2015 The herein presented analytical framework fully describes the motion of coplanar systems consisting of a stellar binary and a planet orbiting both stars on orbital as well as secular timescales.

Combinatorial Screening for Europium Induced Defect Engineering in Titania Anodic Memristors
Advanced Materials Interfaces, EarlyView.A Ti‐Eu thin‐film combinatorial libary (3‐17 at.% Eu) was fabricated by co‐sputtering and anodisation. Systematic screening revealed forming‐free memristors with analog switching, with compositions between 7‐17 at.% Eu showing improved endurance and multilevel resistive states.

Advanced Robotics Research, EarlyView.A novel carbon fiber reinforcement for dielectric elastomer actuators enhances actuation force while decoupling electromechanical performance from the actuator's aspect ratio. Unlike conventional fiber reinforcements, it enables a uniform planar stretch state along the entire actuator.

Kepler-16b: safe in a resonance cell
, 2013 The planet Kepler-16b is known to follow a circumbinary orbit around a system of two main-sequence stars. We construct stability diagrams in the "pericentric distance - eccentricity" plane, which show that Kepler-16b is in a hazardous vicinity to the ...

Kepler-1656b: a Dense Sub-Saturn With an Extreme Eccentricity [PDF]
, 2018 Kepler-1656b is a 5 $R_E$ planet with an orbital period of 32 days initially detected by the prime Kepler mission. We obtained precision radial velocities of Kepler-1656 with Keck/HIRES in order to confirm the planet and to characterize its mass and ...

Constraining the Densities of the Three Kepler-289 Planets with Transit Timing Variations
The Astronomical Journal, 2023 Kepler-289 is a three-planet system containing two sub-Neptunes and one cool giant planet orbiting a young, Sun-like star. All three planets exhibit transit timing variations (TTVs), with both adjacent planet pairs having orbital periods close to the 2:1

Re-examining the light curves of Kepler-6b, Kepler-8b and Kepler-40b
AIP Conference Proceedings, 2018 We present a fresh analysis of the light curves of Kepler-6, Kepler-8 and Kepler-40 star-planet systems using similar to 3 years of observations by the Kepler space telescope. Transit light curves were solved usingWinFitter code. The proximity effects (ellipticity and reflection effects) and Doppler beaming effect were also examined using the Fourier ...

Photochemical Control of Perovskite Crystal Formation at Room Temperature
Advanced Science, EarlyView.The authors demonstrate how ultraviolet (UV) light can enable the crystallization of two‐dimensional (2D) perovskite crystals that are otherwise difficult to grow using conventional thermal methods. These findings are supplemented with a detailed mechanistic description for the interaction of the UV irradiation with the perovskite precursor components.

Multiplicity and properties of Kepler planet candidates: High spatial imaging and RV studies*
EPJ Web of Conferences, 2013 The Kepler space telescope is discovering thousands of new planet candidates. However, a follow up program is needed in order to reject false candidates and to fully characterize the bona-fide exoplanets.
