The physics of deep-interior convective shell boundaries in a massive pre-supernova star: Internal gravity wave mixing at the peak

Praneet Pathak, Falk Herwig, Simon Blouin +2

The physics of convective boundary mixing involves concepts such as penetration and overshooting and has been mostly characterized for envelope and core convection. For the burning…

Wave-Driven Mixing Enhanced by Rotation in Red Giant Branch Stars

Simon Blouin, Paul R. Woodward, Pavel A. Denissenkov +2

Stars like our Sun expand as they exhaust their core hydrogen fuel, becoming red giants that eventually reach sizes up to 100 times their original radius. These giants have long pr…

3D hydrodynamic simulations of massive main-sequence stars -- IV. Internal gravity waves matter for SLF variability

Praneet Pathak, Simon Blouin, Falk Herwig +1

The power spectrum of light curves from satellites like CoRoT and TESS of massive main-sequence stars show stochastic low-frequency (SLF) variability. To investigate the origin of…

Quantifying systematic uncertainties in white dwarf cooling age determinations

Praneet Pathak, Simon Blouin, Falk Herwig

Cooling ages of white dwarfs are routinely determined by mapping effective temperatures and masses to ages using evolutionary models. Typically, the reported uncertainties on cooli…

Enhanced extra mixing in low-mass stars approaching the RGB tip and the problem of Li-rich red-clump stars

Pavel A. Denissenkov, Simon Blouin, Falk Herwig +2

A few percent of red giants are enriched in Lithium with . Their evolutionary status has remained uncertain because these Li-rich giants can be placed both on…
