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 ...

A very luminous, highly extinguished, very fast nova - V1721 Aquilae [PDF]

Astronomy & Astrophysics, 2011
Fast novae are primarily located within the plane of the Galaxy, slow novae are found within its bulge. Because of high interstellar extinction along the line of sight many novae lying close to the plane are missed and only the brightest seen.

Low- and Medium-Dispersion Spectropolarimetry of Nova V475 Sct (Nova Scuti 2003): Discovery of an Asymmetric High-Velocity Wind in a Moderately Fast Nova [PDF]

The Astronomical Journal, 2006
We present low-resolution ($R\sim 90$) and medium-resolution ($R\sim 2500$) spectropolarimetry of Nova V475 Sct with the HBS instrument, mounted on the 0.91-m telescope at the Okayama Astrophysical Observatory, and with FOCAS, mounted on the 8.2-m Subaru

The first orbital period of a very bright and fast Nova in M31: M31N 2013-01b [PDF]

The Astrophysical Journal, 2018
We present the first X-ray and UV/optical observations of a very bright and fast nova in the disc of M31, M31N 2013-01b. The nova reached a peak magnitude $R\sim$15 mag and decayed by 2 magnitudes in only 3 days, making it one of the brightest and ...

A Comprehensive Light-curve Model of the Very Fast Nova V1674 Herculis

The Astrophysical Journal
V1674 Her is one of the fastest novae, of which the very early phase is well observed, including optical rise to the peak over 10 mag. We present a full theoretical light-curve model of V1674 Her.

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.

Nova remnants … the fast siblings of planetary nebulae

Proceedings of the International Astronomical Union, 2023
AbstractClassical and recurrent novae are luminous eruptions taking place in binary star systems in which a white dwarf accretes material from a non-degenerate stellar companion. After the nova event, a shell of gas is expelled and expands into the surrounding environment at hundreds to thousands of km s−1.

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

Nova KT Eri 2009: infrared studies of a very fast and small amplitude He/N nova [PDF]

Monthly Notices of the Royal Astronomical Society, 2013
We present near-infrared spectroscopic and photometric observations of the nova KT Eridani taken during the first 100 days following its discovery in 2009 November. The JHK spectra of the object have been taken from the Mount Abu Infrared Observatory using the Near-Infrared Imager/Spectrometer.
