THE SLOW DEATHS FROM CLIMATE CHANGE: A Planetary View from Papua New Guinea

Cultural Anthropology, Volume 41, Issue 1, Page 57-81, February 2026.
ABSTRACT How do we tell the stories of climate change? This essay explores the slow violence and death experienced by marginalized, racialized, indigenous bodies as climate change differentially impacts communities across the globe. Paying attention to locations beyond the spectacular events that have come to be associated with climate change, the ...

Review of Analytical Lithium Detection and Quantification Methods Along the Lithium Value Chain

Applied Research, Volume 4, Issue 6, December 2025.
This article reviews a selection of suitable state‐of‐the‐art analytical methods for different scales of spatial resolution and detection of lithium for a variety of lithium‐bearing materials along the lithium value chain. The various materials differ greatly in terms of their lithium content by more than 5 orders of magnitude and also vary in their ...

The Impact of Initial Composition on Massive Star Evolution and Nucleosynthesis

The Astrophysical Journal
We study the sensitivity of presupernova evolution and supernova nucleosynthesis yields of massive stars to variations of the initial composition. We use the solar abundances from Lodders, and compute two different sets of initial stellar compositions ...

Predicted gamma-ray line emission from the Cygnus complex

, 2010
The Cygnus region harbours a huge complex of massive stars at a distance of 1.0-2.0kpc from us. About 170 O stars are distributed over several OB associations, among which the Cyg OB2 cluster is by far the most important with about 100-120 O stars. These

Two Micron‐Size Dark Dimensions

Fortschritte der Physik, Volume 73, Issue 8, August 2025.
Abstract Two extra dimensions of micron scale might simultaneously address the gauge and cosmological hierarchy problems. In this paper various observational bounds in scenarios with one and two large extra dimensions are examined, to see if they are compatible with the micron scale.

Observation of interstellar lithium in the low-metallicity Small Magellanic Cloud

, 2012
The primordial abundances of light elements produced in the standard theory of Big Bang nucleosynthesis (BBN) depend only on the cosmic ratio of baryons to photons, a quantity inferred from observations of the microwave background.

Code dependencies of pre-supernova evolution and nucleosynthesis in massive stars: Evolution to the end of core helium burning [PDF]

, 2014
Massive stars are key sources of radiative, kinetic and chemical feedback in the Universe. Grids of massive star models computed by different groups each using their own codes, input physics choices and numerical approximations, however, lead to ...

Nucleosynthesis from massive stars 50 years after B2FH

, 2007
We review some important observed properties of massive stars. Then we discuss how mass loss and rotation affect their evolution and help in giving better fits to observational constraints.
