Analysis of Three Fast Oxygen‐Neon‐Magnesium Novae

Publications of the Astronomical Society of the Pacific, 1998
Since astronomers have only known about the existence of oxygen-neon-magnesium (ONeMg) novae for the last decade, little work has been done on them as a group. The purpose of this work was to study three fast ONeMg novae: V838 Nova Herculis 1991 (Her 91), V693 Nova Coronae Australis 1981 (CrA 81), and Nova LMC 1990 No. 1 (LMC 90a).

An extremely fast fading population II dwarf nova candidate: caught spectroscopically on the rise [PDF]

Monthly Notices of the Royal Astronomical Society
In the first observational run of the Kilonova and Transients Programme (KNTraP), a rapidly evolving optical transient, KNTraP2022-02a (TNS name: AT2022kak), was discovered.

A Multiwavelength Light-curve Analysis of the Very Fast Nova V1723 Sco

The Astrophysical Journal
We have analyzed multiwavelength light curves of the very fast nova V1723 Sco, based on our fully self-consistent nova explosion models. The time-stretching method gives a distance modulus in the V band of ( m  −  M ) _V  = 15.3 ± 0.2. Then, the absolute

A search for extragalactic fast optical transients in the Tomo-e Gozen high-cadence survey [PDF]

Monthly notices of the Royal Astronomical Society, 2023
The population of optical transients evolving within a time-scale of a few hours or a day (so-called fast optical transients, FOTs) has recently been debated extensively. In particular, our understanding of extragalactic FOTs and their rates is limited.

Fast Food and Deprivation in Nova Scotia [PDF]

Canadian Journal of Public Health, 2009
To examine the relationship between density of fast food restaurants and measures of social and material deprivation at the community level in Nova Scotia, Canada.Census information on population and key variables required for the calculation of deprivation indices were obtained for 266 communities in Nova Scotia.

A 9 Month Hubble Space Telescope Near-UV Survey of M87. I. Light and Color Curves of 94 Novae, and a Redetermination of the Nova Rate

The Astrophysical Journal Supplement Series, 2023
M87 has been monitored with a cadence of 5 days over a span of 9 months through the near-ultraviolet (NUV; F275W) and optical (F606W) filters of the Wide Field Camera 3 (WFC3) of the Hubble Space Telescope.

Near-infrared and optical studies of the fast nova V4643 Sgr (Nova Sagittarii 2001) [PDF]

Monthly Notices of the Royal Astronomical Society, 2006
V4643 Sagittarii or Nova Sagittarii 2001 was discovered in outburst at 7.7 mag. on 2001 February 24. Here, we present near-infrared results of this fast classical nova obtained in the early decline phase in 2001 March followed by optical observations about one month later.

BRAT-nova: fast and accurate mapping of bisulfite-treated reads [PDF]

Bioinformatics, 2016
Abstract Summary: In response to increasing amounts of sequencing data, faster and faster aligners need to become available. Here, we introduce BRAT-nova, a completely rewritten and improved implementation of the mapping tool BRAT-BW for bisulfite-treated reads (BS-Seq). BRAT-nova is very fast and accurate. On the human genome, BRAT-nova
