Hydrodynamic Simulations of Oxygen–Neon Classical Novae as Galactic 7Li Producers and Potential Accretion-induced Collapse Progenitors

open access: yesThe Astrophysical Journal
We report on studies of classical nova (CN) explosions where we follow the evolution of thermonuclear runaways (TNRs) on oxygen–neon (ONe) white dwarfs (WDs).

Faith Seeking Prompting: Reimagining Theological Education in the Era of Generative AI

open access: yesTeaching Theology &Religion, Volume 29, Issue 1, Page 61-68, June 2026.
ABSTRACT By juxtaposing Gutenberg's invention of movable type with today's generative‐AI “Gutenberg moment,” this article reimagines theological education in the age of AI. It surveys pioneering implementations of AI in theological education, most notably at Acadia Divinity College, and highlights a growing landscape of AI‐driven courses, chatbots, and

The Powerful Shocks in RS Oph: NuSTAR X-Ray Data and a Complete Review

open access: yesThe Astrophysical Journal
In the 2021 outburst of RS Ophiuchi, the gamma-ray and the X-ray flux were measured quasi-simultaneously from day 1 after the optical peak, offering the first comprehensive view of shocks in a nova occurring in a symbiotic system. We present a previously

Revisiting atmospheric Roche-lobe overflow in symbiotic binaries

open access: yesAstronomy & Astrophysics
Context. Classical binary evolution models predict dynamically unstable mass transfer in symbiotic stars with high mass ratios (qcrit > 1.6), leading to a common envelope (CE).

A Composite Light Curve Model of the Symbiotic Nova PU Vul (1979)

open access: yesOpen Astronomy, 2012
PU Vul (1979) is a symbiotic nova that shows a long-lasting flat optical peak followed by a slow decline. We made a quasi-evolution model for outbursts on a 0.6 M⊙ white dwarf consisting of a series of static solutions with optically-thin winds.

Circumstellar Dust in Symbiotic Novae

open access: yes, 2015
We present a model of inner dust regions around the cool Mira component of the two symbiotic novae, RR Tel and HM Sge, based on the near-IR photometry, ISO spectra and mid-IR interferometry. The dust properties were determined using the DUSTY code.

Morphology, Ultrastructure, and Classification of Barthelonids (Metamonada Incertae Sedis): With Descriptions of Microbarthelona Gen. Nov., and Parabarthelona Gen. Nov.

open access: yesJournal of Eukaryotic Microbiology, Volume 73, Issue 3, May/June 2026.
ABSTRACT Barthelona is a genus of anaerobic flagellates that forms a sister lineage to Fornicata along with Skoliomonas. Although “Barthelona spp.” are known to separate into three distinct lineages, their detailed morphology has not been examined, and their taxonomic classification is incomplete.

Biological Individuality and Fallacies of Composition

open access: yesPhilosophy and Phenomenological Research, Volume 112, Issue 3, Page 628-640, May 2026.
ABSTRACT Within the philosophy of biology, there is widespread acceptance of pluralism about biological individuality, according to which there are (at least) two theoretically important but distinct properties with a claim to the label “biological individuality”: evolutionary individuality and physiological individuality.
