Using dimers to measure biosignatures and atmospheric pressure for terrestrial exoplanets

open access: yes, 2014
We present a new method to probe atmospheric pressure on Earth-like planets using (O-O) dimers in the near-infrared. We also show that dimer features could be the most readily detectable biosignatures for Earth-like atmospheres and may even be detectable

The Path to Future‐Proof Photovoltaics in Europe: Current Status and Impact of Technological Innovation on Reliable and Bankable Photovoltaics

open access: yesAdvanced Energy and Sustainability Research, Volume 7, Issue 6, June 2026.
This article provides an overview of the current state of the art and future improvements in PV technology and explains how changes in the technology and design of individual PV components—at the module level, the balance‐of‐system (BOS) level, or the PV plant level—can affect the reliability, durability, and energy output of a PV system.

The Evolution of Jupiter and Saturn as a Function of the Rρ Parameter

open access: yesThe Astrophysical Journal
Computed using the APPLE planetary evolution code, we present updated evolutionary models for Jupiter and Saturn that incorporate helium rain, nonadiabatic thermal structures, and “fuzzy” extended heavy-element cores.

Giant Planet Lightning in Nonideal Gases

open access: yesThe Planetary Science Journal, 2023
Lightning has been directly observed or inferred on all giant planets, generally accepted to be occurring in their water clouds. However, much as Earth has both cloud–cloud and cloud–ground lightning, this does not mean all flashes occur in a narrow ...

Terrestrial Analogs to Titan for Geophysical Research

open access: yesReviews of Geophysics, Volume 64, Issue 2, June 2026.
Abstract Saturn's moon Titan exhibits remarkable parallels to the Earth in many geophysical and geological processes not found elsewhere in the solar system at the present day. These include a nitrogen atmosphere with a condensible gas—methane—replacing the Earth's water, leading to an active meteorology with rainfall and surface manifestations ...

What Observations Would an Energetic Neutral Atom Imager Have Made During the Voyager 2 Flyby of Uranus?

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 6, June 2026.
Abstract We present large‐scale simulations of energetic neutral atom (ENA) emissions at Uranus from a spacecraft viewpoint. Models of magnetic field, extended hydrogen exosphere, moon‐sourced neutral tori, and proton radiation belt are implemented into a simulator to evaluate the production of ENAs for L $L$ = 1–15.

Propagation and Transmission of Jupiter’s Internal Waves

open access: yesThe Astrophysical Journal
Observations from the Juno spacecraft show that Jupiter has a large dilute core rather than a compact core. To investigate the effects of different core structures on wave propagation and transmission in Jupiter’s interior, we consider three models: (1 ...

Rotation Reduces Convective Mixing in Jupiter and Other Gas Giants

open access: yesThe Astrophysical Journal Letters, 2023
Recent measurements of Jupiter’s gravitational moments by the Juno spacecraft and seismology of Saturn’s rings suggest that the primordial composition gradients in the deep interior of these planets have persisted since their formation.

The Integration of Fire Ecology and Freshwater Ecosystems in North America: Knowledge Gaps and Research Needs

open access: yesGlobal Change Biology, Volume 32, Issue 6, June 2026.
Illustration of key knowledge gaps and pathways linking fire ecology and freshwater ecosystems. Climate change provides the overarching context, interacting with cumulative and cross‐scale effects to shape local freshwater conditions. Within this context, fire characteristics influence three primary pathways within freshwater ecosystems: species and ...

A Pan-STARRS1 Search for Planet Nine

open access: yesThe Astronomical Journal
We present a search for Planet Nine using the second data release of the Pan-STARRS1 survey. We rule out the existence of a Planet Nine with the characteristics of that predicted in Brown & Batygin to a 50% completion depth of V = 21.5.
