Ancient Nova Shells of RX Pup Indicate Evolution of Mass Transfer Rate
The Astrophysical Journal LettersRX Pup is a symbiotic binary that experienced a nova outburst in the 1970s. Here we report a discovery of a ∼1300 yr old nova shell around the system and a possible detection of a ∼7000 yr old nova shell. Together with the nova shell ejected in the 1970s,

Thermonuclear Runaway Models for Symbiotic Novae [PDF]
International Astronomical Union Colloquium, 1988 AbstractThis paper reviews the basic physics of thermonuclear runaways on the surfaces of accreting white dwarf stars, with a special emphasis on understanding the evolution of symbiotic novae.

International Journal of Urban and Regional Research, EarlyView.Abstract Africa is recognized as the final frontier for urbanization and capitalism. Following a long wave of massive loans to promote state‐led developments, small private foreign and local developers are transforming the urban landscape on the outskirts of Luanda, forging partnerships with Angola's national and local governments and developing an ...

CHEMICAL ABUNDANCES OF THE SYMBIOTIC NOVA AG PEGASI [PDF]
Journal of The Korean Astronomical Society, 2008 The high-resolution optical region spectroscopic data of the symbiotic nova AG Peg secured with the Hamilton Echelle Spectrograph at the Lick Observatory, have been analyzed along with the International Ultraviolet Explorer UV archive data. We measure about 700 line intensities in the wavelengths of 3859 to 9230˚ and identify about 300 lines.

The Frontiersmen as an Object of Czech Nationalism 1918–1935
Studies in Ethnicity and Nationalism, EarlyView.ABSTRACT This study investigates the phenomenon of the frontiersmen, that is, the Czech minority border communities, as a part of the discourse of the Czech nationalist movement. Via the example of the Czechoslovak National Democracy party, it traces the frontiersmen on two levels.

Aphid Resistance in Pulse Crops: Sources, Mechanisms, Genetics and Breeding
Legume Science, Volume 8, Issue 4, December 2026.ABSTRACT Aphids are major pests of pulse crops, causing damage through phloem sap feeding and virus transmission. In this context, resistant varieties are central components of sustainable aphid management. This review synthesizes current knowledge on resistance sources, phenotyping strategies, resistance mechanisms, genetic control and breeding ...

Molecular Ecology Resources, Volume 26, Issue 8, November 2026.ABSTRACT The spruce bark beetle Dendroctonus rufipennis (Family: Curculionidae; Subfamily Scolytinae) is a major forest insect pest throughout the transcontinental range of spruce species (Picea spp.) in North America. Here, we present an annotated, near chromosome‐level, genome assembly of 271 Mb, with 86% of the assembly contained in 16 ...

Ultraviolet spectroscopy of old novae and symbiotic stars [PDF]
, 1981 The IUE spectra are presented for two old novae and for two of the symbiotic variables. Prominent emission line spectra are revealed as a continuum whose appearance is effected by the system inclination.
