Re-assessment of type material of Plagiothecium novae-seelandiae Broth. and descriptions of four new Plagiothecium taxa (Bryophyta, Plagiotheciaceae) from Australasia [PDF]
PhytoKeysA re-examination of the original collection of Plagiothecium novae-seelandiae described by Brotherus in 1916 indicated that this material is not homogeneous.

Study of Photometric Variability of Selected SU UMa Dwarf Novae
Acta Polytechnica CTU Proceedings, 2015 In this work we present time-resolved photometry of several poorly-studied dwarf novae during recent superoutbursts. Observations were made with a CCD, mounted on 50- and 60-cm telescopes of the Sternberg Astronomical Institute in Crimea in April - May ...

Search for sub-TeV Neutrino Emission from Novae with IceCube-DeepCore
The Astrophysical Journal, 2023 The understanding of novae, the thermonuclear eruptions on the surfaces of white dwarf stars in binaries, has recently undergone a major paradigm shift. Though the bolometric luminosity of novae was long thought to arise directly from photons supplied by

Theoretical Light-curve Models of the Symbiotic Nova CN Cha—Optical Flat Peak for 3 Yr
The Astrophysical Journal, 2023 CN Cha is a slow symbiotic nova characterized by a 3 yr long optical flat peak followed by a rapid decline. We present theoretical light curves for CN Cha, based on hydrostatic approximation, and estimate the white-dwarf (WD) mass to be ∼0.6 M _☉ for a ...

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.

Theory of Nova Outbursts and Type Ia Supernovae
Acta Polytechnica CTU Proceedings, 2015 We briefly review the current theoretical understanding of the light curves of novae. These curves exhibit a homologous nature, dubbed the universal decline law, and when time-normalized, they almost follow a single curve independently of the white dwarf

Novas histórias, novas personagens
Revista de Estudos Literários, 2022 Uma das possiblidades de sobrevida da personagem, na perspectiva de uma teoria da figuração, projetada pelo crítico Carlos Reis, é a sua incorporação a uma narrativa subsequente àquela em que foi originalmente construída. A mulher do médico, por exemplo, é concebida na célebre obra Ensaio sobre a cegueira, de José Saramago, e refigurada como personagem

Odessa Astronomical Publications, 2007 The WZ Sge type stars is a rare subclass of the cataclysmic variables (CVs). It possesses the properties of both dwarf novae and recurrent novae. The WZ Sge stars have the shortest orbital periods (typically 80 - 90 minutes) known among the dwarf novae ...

Two-Color VR CCD Photometry of Old Nova V603 Aquilae [PDF]
Journal of Astronomy and Space Sciences, 2005 Results of 6 nights of CCD VR photometry of the nova-like variable V603 Aquilae (Nova Aquilae 1918) obtained at the Mallorcian 35-cm telescope in July 2004 are reported.
