Vou lš para o outro quarto, pois lš a mesa é maior e acaba sendo um lugar mais confortšvel pra corrigir provas e trabalhos. O ruim é que meu idoso computador de lš aparentemente pifou e eu não tive tempo de abrí-lo pra tentar descobrir exatamente o que aconteceu.

Curiosidade antropológica em #Curitiba : você vai Šs praças de alimentação e as pessoas deixam as bolsas para "ocupar o lugar" enquanto se servem.
Mas ao sair da mesa, elas levam as bandejas aos repositórios.

Analysis and Numerical Approximation to Interactive Dynamics of Navier Stokes-Plate Interaction PDE System
We consider a Navier-Stokes fluid-plate interaction (FSI) system which describes the evolutions of the fluid contained within a 3D cavity, as it interacts with a deformable elastic membrane on the ``free" upper boundary of the cavity. These models arise in various aeroelastic and biomedical applications as well as in the control of ocular pressure, and sloshing phenomena. We analyze the well-posedness of weak solutions to the stationary ($λ$-parametrized) coupled PDE system by way of invoking …

Hydrodynamical modelling of Type IIb SNe
We present HYDE, a new one-dimensional hydrodynamical code, and use it to construct a grid of supernova (SN) models based on solar-metallicity bare helium-core models evolved to the verge of core-collapse with MESA STAR. This grid is suited to model Type IIb SNe, which progenitor stars are thought to have lost all but a tiny fraction of their hydrogen envelopes. Using an automated procedure we fit the bolometric lightcurves and photospheric velocities for a large sample of (17) Type IIb SNe to …

The role of bars in triggering active galactic nuclei galaxies
Bars are considered an efficient mechanism for transporting gas toward the central regions of galaxies, potentially enhancing nuclear activity. However, the extent to which bars influence active galactic nuclei (AGNs), and whether their efficiency varies with environment, remain open questions. In this study, we aim to quantify the role of bars in triggering AGNs by comparing the AGN fraction in barred and non-barred galaxies across different environments. We constructed a sample from the Galax…

Metal-poor single Wolf-Rayet stars: the interplay of optically thick winds and rotation
The Small Magellanic Cloud (SMC) hosts 12 known Wolf-Rayet stars (WRs), seven of which apparently single. Their formation is a challenge for current stellar evolution models, because line-driven winds are generally assumed to be quenched at a metallicity Z<0.004. Here, we present a set of MESA models of single stars with zero-age main sequence masses 20-80 M_sun, considering different initial rotation speeds (Omega=0-0.7 Omega_c), metallicities (Z=0.002-0.0045), and wind mass-loss models (optic…

Three-component Phase Separation for Ultramassive White Dwarf Models
We investigate phase separation in oxygen-neon (O/Ne) ultramassive white dwarfs (UMWDs). Current stellar evolution codes, such as MESA, only account for $\mathrm{^{16}O/^{20}Ne}$ separation and do not include other minor species. To improve this, we implement ternary phase diagrams into MESA. We construct UMWD models with O/Ne/sodium (Na) and O/Ne/magnesium (Mg) cores to test our implementation. We also assess the effect of including $\mathrm{^{22}Ne}$ in the current two-species framework. Our …
