Insights from Asteroseismology of Massive Stars: The Need for Additional Angular Momentum Transport Mechanisms
No full textIn massive stars, rotation and oscillatory waves can have a tight interplay. In order to assess the importance of additional angular momentum transport mechanisms other than rotation, we compare the asteroseismic properties of a uniformly rotating model and a differentially rotating one. Accordingly, we employ the observed period spacing of 36 dipole g-modes in the Kepler ~ 3.2M⊙ target KIC 7760680 to discriminate between these two models. We favor the uniformly rotating model, which fully satisfies all observational constraints. Therefore, effcient angular momentum transport by additional mechanisms such as internal gravity waves, heat-driven modes and magnetic field is needed during early main sequence evolution of massive stars

The impact of enhanced iron opacity on massive star pulsations: updated instability strips
No full textRecently, Bailey et al. (2015) made a direct measurement of the Iron opacity
at the physical conditions of the solar tachocline.
They found that the wavelength-integrated Iron opacity is roughly 75% higher
than what the OP and OPAL models predict.
Here, we compute new opacity tables with enhanced Iron and Nickel contributions to the
Rosseland mean opacity by 75% each, and compute three dense MESA grids of evolutionary models
for Galactic O- and B-type stars covering from 2.5 to 25 M_sun from ZAMS until
T_eff=10 000 K after the core hydrogen exhaustion.
We carry out non-adiabatic mode stability analysis with GYRE, and update the
extension of
the instability strips of heat-driven p- and g-mode pulsators, and the hybrid pulsating
SPB - beta Cep stars.
We compare the position of two confirmed late O-type beta Cep and eight confirmed
hybrid B-type pulsators with the new instability domains, and justify that ~75%
enhancement, only in Iron opacity, is sufficient to consistently reproduce the observed
position of these stars on the log T_eff versus log g plane.
We propose that this improvement in opacities be incorporated in the input physics
of new stellar models.sponsorship: The research leading to these results has received funding from the People Programme (Marie

PARASO source code (no COSMO)
No full textSource code for the PARASO Antarctic configuration, except the COSMO model (atmosphere), which is only accessible to CLM-Community members (free membership charge for all research applications). A full version of these sources, including the COSMO part, has been uploaded to the CLM-Community RedC under "Downloads" -> "COSMO-CLM".
Hence, these sources are provided for dicdactical purposes, not for running the full model (which requires COSMO).

Deep Characterization of SARS-CoV-2: An Overview
No full textThe coronavirus epidemic has become one of the major health concerns all over the world recently. Like other strains of coronavirus, this strain also spreads through a droplet-based transmission that is the main cause of its worldwide spread. Several trials of antiviral medicines related to the control of the virus have already begun globally but still one of the main problems is the lack of a viable treatment option. An extensive amount of research is still taking place to organize the data associated with genomics and proteomics of its original strain SARS-CoV-2 alongside other mutant strains. This review summarizes the related up-to-date research that is going on the structural organization of the genome and proteome of the virus.

Perspectives on decentralization past, present, and future: a review of conferences in Grenoble, Milan, and Delft (2017–2019)
No full textDecentralization has actively engaged various fields of sociology, economy, and governance in the development of urban regions and territories. As a multifaceted strategy, decentralization contributes to enrich our understanding of national and international forces, power struggles, economic factors, and their impacts on the built environment. To frame the discourse of decentralization on urban development, three institutions of ENSAG Université Grenoble Alpes, Politecnico di Milano, and the Delft University of Technology closely collaborated to organize three conferences in Grenoble, Milan, and Delft, respectively. They called scholarly attention re-thinking of urban and regional planning of the twentieth century through the lens of decentralization’s values and ideologies. These three conferences laid out how decentralization and its evolution engaged with the field of planning, and in turn, affected urban transformation and regional development worldwide. Focusing on the role of decentralization in urban and regional planning, these scholarly events offered an innovative perspective on research on planning history. This report, therefore, reflects upon the discussions took place at these three conferences to outline the diversity of perspectives on decentralization and its role in urban and regional planning in the past, present, and future
