Models for the soft X-ray emission of post-outburst classical novae

, 2005
A hydrostatic and stationary white dwarf envelope model has been developed for the study of the post-outburst phases of classical novae and their soft X-ray emission.

Characterization and Antimicrobial Activity of Hafnium Nanostructures Fabricated by Physical Vapor Deposition Through a Colloidal Mask

Advanced Materials Interfaces, EarlyView.
We generate hafnium nanostructures by first depositing polystyrene particles of varying diameter followed by physical vapour deposition of hafnium thin films. The resultant structure shows a kill‐on‐contact effect against both Gram‐negative Escherichia coli and Gram‐positive Staphylococcus aureus.

The UBV Color Evolution of Classical and Symbiotic Novae

Acta Polytechnica CTU Proceedings, 2015
We identified a general course of classical nova outbursts in the B − V vs. U − B diagram. It has been reported that novae show spectra similar to A–F supergiants near optical light maximum.

Recurrent Nova IM Normae

, 2002
We detected the second historical outburst of the 1920 nova IM Nor. Accurate astrometry of the outbursting object revealed the true quiescent counterpart having a magnitude of R=17.0 mag and B=18.0 mag.

Novas tecnologias, novas competências [PDF]

Educar em Revista, 2008
O texto aborda a relação dos jovens e adolescentes com tecnologias, nem "novas" nem "velhas", e sim instrumentos para informar e comunicar, divertir, auxiliar nos trabalhos escolares. Apesar de reconhecer a familiaridade dessa geração com o que há de mais avançado em termos de tecnologia, aponta a necessidade de se compreender a complexidade desse novo

On the Light Curves of Disk and Bulge Novae

The Astrophysical Journal
We examine the light curves of a sample of novae, classifying them into single-peaked and multiple-peaked morphologies. Using accurate distances from Gaia, we determine the spatial distribution of these novae by computing their heights, Z , above the ...

First Direct Measurement of the ^{17}O(p,\gamma)^{18}F Reaction Cross-Section at Gamow Energies for Classical Novae

, 2012
Classical novae are important contributors to the abundances of key isotopes, such as the radioactive ^{18}F, whose observation by satellite missions could provide constraints on nucleosynthesis models in novae.

Large‐Scale and Cost‐Effective Fabrication of Ultra‐Thin, Biodegradable Microelectrode Arrays and Pressure Sensors Using Laser Micromachining

Advanced Materials Technologies, EarlyView.
A mask‐free and cost‐effective UV‐pico‐second laser‐based microfabrication method is proposed to fabricate large‐area biodegradable microelectrode arrays and pressure sensors. These devices demonstrate low impedance, good conformability, excellent biocompatibility, and rapid degradation, providing a new route for next‐generation transient electronics ...

Fully Self-consistent Nova Explosion Models Reproducing Light Curves of KT Eri, V339 Del, V597 Pup, and SMC NOVA 2016-10a

The Astrophysical Journal
The rising phase toward the optical maximum of a classical nova is one of the last frontiers of nova study. Constructing free–free emission model light curves based on our fully self-consistent nova explosion models, we present several theoretical light ...
