Composition of the Innermost Core‐Collapse Supernova Ejecta [PDF]

The Astrophysical Journal, 2006
With presently known input physics and computer simulations in 1D, a self-consistent treatment of core collapse supernovae does not yet lead to successful explosions, while 2D models show some promise. Thus, there are strong indications that the delayed neutrino mechanism works combined with a multi-D convection treatment for unstable layers.

First Detection of [SI] in Near‐IR JWST Observations of Io in Eclipse, and Comparison With SO Emissions, Evolving Volcanic Eruptions, and Prior UV HST‐STIS [SI] Emissions

Journal of Geophysical Research: Planets, Volume 130, Issue 11, November 2025.
Abstract We observed Io with the James Webb Space Telescope (JWST) NIRSpec/Integral Field Unit (1.0–5.3 μm, R∼2700 $R\sim 2700$) in August 2023 while the satellite was in eclipse. Thermal emission from Kanehekili Fluctus is consistent with the cooling of lava flows after a vigorous eruption in November 2022.

Near-infrared Spectroscopy of Dense Ejecta Knots in the Outer Eastern Area of the Cassiopeia A Supernova Remnant

The Astrophysical Journal, 2023
The Cassiopeia A supernova remnant has a complex structure, manifesting the multidimensional nature of core-collapse supernova explosions. To further understand this, we carried out near-infrared multiobject spectroscopy on the ejecta knots located in ...

Long gamma-ray bursts and core-collapse supernovae have differentenvironments [PDF]

, 2006
When massive stars exhaust their fuel they collapse andoften produce the extraordinarily bright explosions known ascore-collapse supernovae. On occasion, this stellar collapse also powersan even more brilliant relativistic explosion known as a long ...

A Flight Back to Ground: Jung’s Recalcitrant Fourth as Rape into Consciousness. Symbolic Rape and Literal Rape in Persephone’s Myth

Journal of Analytical Psychology, Volume 70, Issue 4, Page 616-639, September 2025.
Abstract Patricia Berry’s interpretation of the Demeter/Persephone myth, and her concept of rape into consciousness, illuminate intrapsychic dynamics. However, this symbolic lens may inadvertently distance us from the devastating nature of literal rape—a reality the Homeric Hymn encapsulates.

Assembling genomes of non‐model plants: A case study with evolutionary insights from Ranunculus (Ranunculaceae)

The Plant Journal, Volume 123, Issue 6, September 2025.
SUMMARY Whereas genome sequencing and assembly technologies are improving, cost can still be prohibitive for plant species with large, complex genomes. As a consequence, genomics work on some taxa in evolutionarily pivotal positions in the vascular plant tree of life has been hampered.
