Revisiting atmospheric Roche-lobe overflow in symbiotic binaries
Astronomy & AstrophysicsContext. 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).

Automation and Augmentation in Theological Perspective
Modern Theology, Volume 42, Issue 3, Page 612-628, July 2026.Abstract AI enables forms of automation that threaten unemployment and deskilling, eliminating important opportunities for the development of virtue. The concomitant loss of virtue and meaningful employment makes it a theological problem from the perspective of Catholic social teaching and theological anthropology.

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

The Astrophysical JournalA popular solution to the Type Ia supernova (SN Ia) progenitor problem is that the immediate progenitors are symbiotic star systems. This solution requires that the companion star of the exploding white dwarf must be a red giant star with a heavy stellar

Gamma rays from Nebulae around Recurrent Novae [PDF]
, 2023 Novae were discovered to emit transient gamma rays during the period of several days to a few weeks after initial explosion, indicating presence of acceleration processes of particles in their expanding shells.

V1047 Cen: The First Z And-type Outburst Observed in the Classical Nova Binary
The Astrophysical JournalIn 2019, the classical nova V1047 Cen experienced an unusual outburst, the nature of which has not yet been clearly determined. In this paper, we show that the 2019 V1047 Cen outburst is of Z And-type—a type that is characteristic of and has so far been ...

Exploring Mass Transfer Mechanisms in Symbiotic Systems
The Astrophysical JournalWe define two regimes of the parameter space of symbiotic systems based on the dominant mass transfer mechanism. A wide range of white dwarf (WD) mass, donor mass, and donor radius combinations are explored to determine the separation for each parameter ...

CHARA Array Observations of the Evolved Components in Symbiotic Star Systems
The Astrophysical JournalThe nature of the mechanisms that drive mass transfer in symbiotic stars remains an area of active research in stellar astronomy. Constraining the role that both stellar winds and Roche-lobe overflow play in this process is crucial to improving our ...
