Instabilities in the Envelopes and Winds of Very Massive Stars

, 2014
The high luminosity of Very Massive Stars (VMS) means that radiative forces play an important, dynamical role both in the structure and stability of their stellar envelope, and in driving strong stellar-wind mass loss.

Detailed opacity calculations for astrophysical applications

, 2017
Nowadays, several opacity codes are able to provide data for stellar structure models, but the computed opacities may show significant differences. In this work, we present state-of-the-art precise spectral opacity calculations, illustrated by stellar ...

Instability strips of SPB and beta Cephei stars: the effect of the updated OP opacities and of the metal mixture [PDF]

, 2006
The discovery of $\beta$ Cephei stars in low metallicity environments, as well as the difficulty in theoretically explaining the excitation of the pulsation modes observed in some $\beta$ Cephei and hybrid SPB-$\beta$ Cephei pulsators, suggest that the ``

Reality and truthfulness. Abstraction, (hyper)realism and the “post-pictorial condition”

piano b, 2017
In the Aristotelian tradition image is seen as likeness and imitation of the natural world that exists outside the image. Classical art therefore strived to become as natural as possible, in order to imitate worldly creatures through semblances with ...

Electron density in the quiet solar coronal transition region from SoHO/SUMER measurements of S VI line radiance and opacity

, 2009
Context: The sharp temperature and density gradients in the coronal transition region are a challenge for models and observations. Aims: We set out to get linearly- and quadratically-weighted average electron densities in the region emitting the S VI ...

The Route to Artery Mimetics: Hybrid Bioinks for Embedded Bioprinting of Multimaterial Cylindrical Models

Advanced Functional Materials, EarlyView.
The fabrication of a cellularized, multilayered 3D printed cylindrical model comprising hybrid bioinks inspired by the natural extracellular environment as an approach to artery mimetics, is presented. Using embedded bioprinting, interlayer crosslinking of self‐supporting concentric cylinders is achieved.
