Recurrent novae: Single degenerate progenitors of Type Ia supernovae
, 2020 Type Ia supernovae are the result of explosive thermonuclear burning in CO white dwarfs. The progenitors of the Ia supernovae are white dwarfs in an interacting binary system.

Novae: An Important Source of Lithium in the Galaxy
The Astrophysical JournalThe source of the Galactic lithium (Li) has long been a puzzle. With the discovery of Li in novae, extensive research has been conducted. However, there still exists a significant disparity between the observed abundance of Li in novae and the existing ...

Effects of Landscape Structure and Roads on Anuran Assemblages in the Brazilian Cerrado
Austral Ecology, Volume 51, Issue 10, October 2026.ABSTRACT The Brazilian Cerrado harbours a highly diverse and well‐represented anuran fauna, yet the effects of anthropogenic factors, such as roads, habitat loss and fragmentation, on these assemblages remain poorly understood. In the present study, we address this knowledge gap by testing the relationship between landscape metrics and anuran assembly (

The Landless Rural Workers Movement (MST) and New Agrarian Questions in Brazil
Journal of Agrarian Change, Volume 26, Issue 4, October 2026.ABSTRACT The Landless Rural Workers Movement of Brazil (MST) primarily organized occupations of large‐scale farms, forcing the redistribution of land for creation of agrarian reform settlements. In the past 20 years, however, land occupations and the establishment of new agrarian reform settlements have consistently declined, while the MST shifted ...

The Rise of Nova V1674 Herculis
The Astrophysical JournalObservational constraints on classical novae are heavily biased to phases near optical peak and later because of the simple fact that novae are not typically discovered until they become bright. The earliest phases of brightening, coming before discovery,
