Recent progress in understanding the eruptions of classical novae [PDF]

open access: yes
Dramatic progress has occurred in the last two decades in understanding the physical processes and events leading up to, and transpiring during the eruption of a classical nova.

Remarkable changes in the near-infrared spectrum of the nova-like variable V4332 Sgr

open access: yes, 2003
We report on recent near-IR observations of V4332 Sgr - the nova-like variable that erupted in 1994. Its rapid, post-outburst evolution to a cool M type giant/supergiant, soon after its outburst, had showed that it was an unusual object differing from ...

Discovery and Initial Investigation of a New Low Surface Brightness Planetary Nebula Candidate at High Galactic Latitude

open access: yesAstronomische Nachrichten, EarlyView.
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 ...

The unreasonable effectiveness of experiments in constraining nova nucleosynthesis

open access: yesEPJ Web of Conferences, 2014
Classical nova explosions arise from thermonuclear ignition in the envelopes of accreting white dwarfs in close binary star systems. Detailed observations of novae have stimulated numerous studies in theoretical astrophysics and experimental nuclear ...

Exosome as bioactive nanovesicle for diagnostic and therapeutic applications in periodontitis

open access: yesBMEMat, EarlyView.
This review introduces the mechanism that exosomes participate in the pathogenesis of periodontitis and their potential as biomarkers for early diagnosis and summarizes the application of cell‐ or plant‐derived exosomes or engineered exosomes in periodontitis or periodontal regeneration while proposing the perspective of translational application of ...

Pulmonalis or Pulmonaris? It's Elementarius, My Dear Watson

open access: yesClinical Anatomy, EarlyView.
ABSTRACT The adjectival suffix ‐alis and its allomorph ‐aris are very common in the anatomical nomenclature; however, rules governing differential usage, such as ‐aris substituting for ‐alis following an ‐l‐, leave many exceptions. Here, we report an empirical study of 985 adjectives with ‐alis and ‐aris suffixes used in Terminologia Anatomica (2nd ed.)

A Multiwavelength Light-curve Analysis of the Classical Nova KT Eri: Optical Contribution from a Large Irradiated Accretion Disk

open access: yesThe Astrophysical Journal
KT Eri is a classical nova that went into outburst in 2009. Recent photometric analysis in quiescence indicates a relatively longer orbital period of 2.6 days, so that KT Eri could host a very bright accretion disk during the outburst like in the ...

Fascia, Eh. What Is It? What Is It Good for?

open access: yesClinical Anatomy, EarlyView.
ABSTRACT Opinions on the meaning of the term fascia appear to have been diverging for the past quarter century. In 1998, the definition of fascia in the international standard anatomical nomenclature was narrowed by removing the term fascia superficialis.

Optical Detection of the X-Ray Flash in the Very Fast Nova V1674 Her: Optical Contribution of the Irradiated Accretion Disk

open access: yesThe Astrophysical Journal
V1674 Her is one of the fastest and brightest novae, characterized by dense optical photometry in the premaximum phase—a rise from g = 17 to 7 mag, over one-quarter of a day.

Classical novae and type I X-ray bursts: Challenges for the 21st century

open access: yesAIP Advances, 2014
Classical nova explosions and type I X-ray bursts are the most frequent types of thermonuclear stellar explosions in the Galaxy. Both phenomena arise from thermonuclear ignition in the envelopes of accreting compact objects in close binary star systems ...
