The Astrophysical JournalThe rising phase toward the optical maximum of a classical nova is one of the last frontiers of nova study. Constructing free–free emission model light curves based on our fully self-consistent nova explosion models, we present several theoretical light ...

Parasitic Plant–Host Interactions: Molecular Mechanisms and Agricultural Resistance Strategies
Advanced Science, Volume 13, Issue 16, 18 March 2026.Parasitic plants devastate global agriculture through sophisticated molecular interactions with host crops. This review synthesizes current understanding of parasitic plant‐host interactions, from strigolactone‐mediated germination and haustorium formation to host defense mechanisms.

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,

Phylogenetic systematics of Juncaceae
American Journal of Botany, Volume 113, Issue 3, March 2026.Abstract Premise Juncaceae has needed taxonomic revision for some time. Specifically, the genus Juncus s.l. is known to be paraphyletic because five small southern‐hemisphere genera have been shown repeatedly to be nested within it. In 2022, a new classification was proposed, based on phylogenies built from one nuclear and three plastid regions ...

EVIDENCE OF A BROWN DWARF IN THE ECLIPSING DWARF NOVA Z CHAMAELEONIS
The Astrophysical Journal, 2009 We presented three new CCD observations of light minima of Z Chamaeleonis. All 187 available times of light minimum including 37 photographic data are compiled, and a new orbital period analysis is made by means of the standard O - C technique. The O - C diagram of Z Chamaeleonis presents a cyclical periodic change of similar to 32.57 yr with a high ...

Astronomische Nachrichten, Volume 347, Issue 3, March 2026.ABSTRACT Planetary nebulae represent a late evolutionary phase of low‐ to intermediate‐mass stars. In this article, we present the serendipitous discovery of a previously unknown, faint potential Galactic planetary nebula (PN) in the constellation Camelopardalis, identified during a survey‐inspection, aiming at the detection of dwarf companions of the ...

Low-metallicity Nova Explosions: A Site for Weak rp-process Nucleosynthesis
The Astrophysical JournalClassical novae are common cataclysmic events involving a binary system of a white dwarf and a main-sequence or red giant companion star. In metal-poor environments, these explosions produce ejecta differently from their solar counterparts due to the ...

OUTBURST CYCLICITY OF DWARF NOVA VZ AQUARII
Odessa Astronomical Publications, 2017 New linear elements for outbursts of VZ Aqr from 1904 to 1987 were obtained with P0 = 50.4053d. Two states of outburst activity are distinguished with cycle lengths 47.128d and 55.041d, replacing each other during Π = 13.2yr and accompanied by a maximum ...
