Formation and Evolution of Planetary Systems in Presence of Highly Inclined Stellar Perturbers [PDF]

open access: yes, 2011
The presence of highly eccentric extrasolar planets in binary stellar systems suggests that the Kozai effect has played an important role in shaping their dynamical architectures.

Element sets for high-order Poincar\'e mapping of perturbed Keplerian motion [PDF]

open access: yes, 2018
The propagation and Poincar\'e mapping of perturbed Keplerian motion is a key topic in celestial mechanics and astrodynamics, e.g. to study the stability of orbits or design bounded relative trajectories. The high-order transfer map (HOTM) method enables

Platinum Group Element Traces of CAMP Volcanism Associated With Low‐Latitude Environmental and Biological Disruptions

open access: yesGeophysical Monograph Series, Page 263-304., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

On the nature of an ejection event in the jet of 3C111

open access: yes, 2008
We present a possible scenario for the ejection of a superluminal component in the jet of the Broad Line Radio Galaxy 3C111 in early 1996. VLBI observations at 15 GHz discovered the presence of two jet features on scales smaller than one parsec.

Low‐Energy, Ultrafast Spin Reorientation at Competing Hybrid Interfaces with Tunable Operating Temperature

open access: yesAdvanced Materials, EarlyView.
A spin reorientation transition is generated at hybrid interfaces of Pt‐Co‐organic molecules in the vicinity of room temperature. This spin reorientation transition happens at an ultrafast scale and is controlled either through electrical current or fs laser pulse, introducing perpendicular magnetic anisotropy in formerly planar magnetised samples ...

Higher Order Approximation to the Hill Problem Dynamics about the Libration Points

open access: yes, 2018
An analytical solution to the Hill problem Hamiltonian expanded about the libration points has been obtained by means of perturbation techniques. In order to compute the higher orders of the perturbation solution that are needed to capture all the ...

Properties of Central Caustics in Planetary Microlensing [PDF]

open access: yes, 2005
To maximize the number of planet detections, current microlensing follow-up observations are focusing on high-magnification events which have a higher chance of being perturbed by central caustics.

HZO/HSO Superlattice ReFET Array Integrating Optical Sensing for Neuromorphic Vision Computing

open access: yesAdvanced Materials, EarlyView.
A photonic ReFET array with an engineered HZO–HSO superlattice enables monolithic integration of optical sensing, nonvolatile memory, and synaptic computation. It exhibits forming‐free, >8‐bit analog states, >1010 endurance cycles, and light‐tunable conductance.

The Solar Neighborhood XXXI: Discovery of an Unusual Red+White Dwarf Binary at ~25 Parsecs via Astrometry and UV Imaging

open access: yes, 2013
We report the discovery of a nearby M5.0V dwarf at 24.6 pc, SCR 1848-6855, that is orbited by an unusual companion causing an astrometric perturbation of more than 200 milli-arcseconds.

Transition‐Metal Azo Schiff Base Complexes: Nonlinear Optics Across Solutions, Thin Films and Nanocomposites

open access: yesAdvanced Optical Materials, EarlyView.
The excitation of a transition‐metal azo Schiff‐base complex with a 1064 nm laser induces a series of nonlinear optical effects. These effects include the second harmonic generation at 532 nm and third harmonic generation at 355 nm. This process demonstrates the potential of the complex for high‐order nonlinear optical applications. Abstract This paper
