Low-metallicity Nova Explosions: A Site for Weak rp-process Nucleosynthesis

open access: yesThe Astrophysical Journal
Classical 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 ...

Planting date and seeding rate effect on winter malting barley grain yield and quality in northwest Ohio

open access: yesCrop, Forage &Turfgrass Management, Volume 12, Issue 1, June 2026.
Abstract With the growth in the craft brewing industry, farmers are interested in producing winter malting barley (Hordeum vulgare L.). Timely barley planting is important; however, wet weather often results in delays. The objective of this experiment was to identify the agronomic optimum seeding rate (the seeding rate at which yield is maximized) for ...

Comprehensive Listing of 208 Nova White Dwarf Masses as the Primary Determinant of Spectral Class and Light-curve Class

open access: yesThe Astrophysical Journal
For Galactic novae, I calculate and collect a comprehensive catalog of 208 measures of white dwarf (WD) masses ( M _WD ) and 232 measures of average V magnitudes in quiescence ( V _q ). These are collected into a comprehensive catalog of most fundamental

Mammal Community Responses to Increasing Puma Activity in a Suburban Preserve

open access: yesEcology and Evolution, Volume 16, Issue 6, June 2026.
Using nine years of camera‐trap data from a suburban preserve, we found preliminary, convergent evidence that increasing puma activity coincided with changes in black‐tailed deer, bobcat and coyote activity. Evidence for changes in brush rabbit and grey fox activity, as well as woody plant density, is more tentative and warrants further study, but ...

Spectroscopic analysis of the dwarf nova SS Cygni

open access: yes, 2010
Dwarf novae are a type of cataclysmic variable in which one of the components is a white dwarf. Their outbursts can range in brightness from two to five magnitudes at intervals that can vary from days to decades. The purpose of this study is to analyze

Recurrent novae [PDF]

open access: yes, 1993
Recurrent novae seem to be a rather inhomogeneous group: T CrB is a binary with a M III companion; U Sco probably has a late dwarf as companion. Three are fast novae; two are slow novae. Some of them appear to have normal chemical composition; others may

OUTBURST CYCLICITY OF DWARF NOVA VZ AQUARII

open access: yesOdessa 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 ...
