Wide angle search for extrasolar planets by the transit method [PDF]

, 2008
The transit method is considered to be one of the most promising for discovering extrasolar planets. However, the method requires photometric precision of better than ∼ 1%.

Hybrid Additive Manufacturing of Highly Stretchable Bottlebrush Polymer Nanocomposites by Decoupled Extrusion and Photopatterning

Advanced Materials Technologies, EarlyView.
A Hybrid Direct Ink Writing–Digital Light Processing (HDD) strategy decouples material extrusion from shape definition, enabling high‐fidelity additive manufacturing of highly viscous, yield‐stress polymer nanocomposites. Excess ink acts as a removable, self‐supporting scaffold, allowing fabrication of unsupported and embedded complex architectures ...

Aerosol Jet Printing of Benzocyclobutene as a Thermally Stable, Low‐Loss Dielectric for Multilayer Microwave Electronics

Advanced Materials Technologies, EarlyView.
Multilayer aerosol jet printed components with a low‐loss, thermally stable dielectric are demonstrated using benzocyclobutene. Ink formulation and in‐line droplet evaporation control support high‐quality, versatile, and stable printing performance. A specialized measurement for low‐loss materials reveals promising microwave properties, which, combined

Occurrence Rates of Exosatellites Orbiting 3–30 M Jup Hosts from 44 Spitzer Light Curves

The Astronomical Journal
We conduct a comprehensive search for transiting exomoons and exosatellites within 44 archival Spitzer light curves of 32 substellar worlds with estimated masses ranging between 3 and 30 M _Jup . This sample’s median host mass is 16 M _Jup , inclusive of

Detectability of Free Floating Planets in Open Clusters with JWST

, 2013
Recent observations have shown the presence of extra-solar planets in Galactic open stellar clusters, as in the Praesepe (M44). These systems provide a favorable environment for planetary formation due to the high heavy-element content exhibited by the majority of their population. The large stellar density, and corresponding high close-encounter event

Coordination‐Actuated Photonic Microparticles for Recyclable, High‐Resolution Heavy Metal Sensing Via Structural Color

Advanced Optical Materials, EarlyView.
A colloidal photonic sensing platform converts heavy metal coordination into vivid structural color changes. PS‐b‐P2VP microparticles with an interpenetrating polypyrrole/P2VP network exhibit cooperative metal ion binding that contracts lamellar microdomains and blue‐shifts Bragg reflections.

A Deep Search for Exomoons around WISE 0855 with JWST

The Astronomical Journal
The James Webb Space Telescope (JWST) is collecting time-series observations of many free-floating planets (FFPs) to study their weather, but these light curves provide ideal datasets for locating exomoons that transit FFPs during observations.

Micromachined Double‐Membrane Mechanically Tunable Metamaterial for Thermal Infrared Filtering

Advanced Photonics Research, Volume 6, Issue 5, May 2025.
Herein, a mechanically tunable double‐layer plasmonic metamaterial leveraging the extraordinary optical transmission effect observed in subwavelength arrays of openings within thin metal layers is presented. The concept is experimentally validated by integrating the proposed metamaterial structure into an electrostatic parallel‐plate actuator to create

Dynamical evolution of massless particles in star clusters with NBODY6++GPU-MASSLESS

Astronomy & Astrophysics
Context. Comets, asteroids, planetesimals, free-floating planets, and brown dwarfs are continuously injected into the intracluster environment after expulsion from their host-planetary systems or binary system.

Free-floating planets: a viable option for panspermia

, 2010
Genomic complexity can be used as a clock with which the moment in which life originated can be measured. Some authors who have studied this problem have come to the conclusion that it is not possible that terrestrial life originated here and that, in reality, life originated giga-years ago, before the solar system existed. If we accept this conclusion
