Detection and Preliminary Characterisation of Polluted White Dwarfs from Gaia EDR3 and LAMOST
Mariona Badenas-Agusti, Andrew Vanderburg, Simon Blouin +4
We present a catalogue of 62 polluted white dwarfs observed by the 9th Low-Resolution Data Release of the Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST LRS DR9v…
The Q Branch Cooling Anomaly Can Be Explained by Mergers of White Dwarfs and Subgiant Stars
Ken J. Shen, Simon Blouin, Katelyn Breivik
Gaia's exquisite parallax measurements allowed for the discovery and characterization of the Q branch in the Hertzsprung-Russell diagram, where massive C/O white dwarfs (WDs) pause…
3D hydrodynamics simulations of a 3 core-helium burning star
Simon Blouin, Falk Herwig, Huaqing Mao +2
The inner structure of core-helium burning (CHeB) stars remains uncertain due to the yet unknown nature of mixing at the boundary of their cores. Large convective cores beyond a ba…
The ubiquity of carbon dredge-up in hydrogen-deficient white dwarfs as revealed by GALEX
Simon Blouin, Mukremin Kilic, Antoine Bédard +1
The convective dredge-up of carbon from the interiors of hydrogen-deficient white dwarfs has long been invoked to explain the presence of carbon absorption features in the spectra…
A Crystallizing White Dwarf in a Sirius-Like Quadruple System
Alexander Venner, Simon Blouin, Antoine Bédard +1
The observational signature of core crystallization of white dwarfs has recently been discovered. However, the magnitude of the crystallization-powered cooling delay required to ma…
Carbon dredge-up required to explain the Gaia white dwarf colour-magnitude bifurcation
Simon Blouin, Antoine Bédard, Pier-Emmanuel Tremblay
The Gaia colour--magnitude diagram reveals a striking separation between hydrogen-atmosphere white dwarfs and their helium-atmosphere counterparts throughout a significant portion…
3D hydrodynamic simulations of massive main-sequence stars. III. The effect of radiation pressure and diffusion leading to a 1D equilibrium model
Huaqing Mao, Paul Woodward, Falk Herwig +4
We present 3-D hydrodynamical simulations of core convection with a stably stratified envelope of a \unit{25}{\Msun} star in the early phase of the main-sequence. We use the explic…
3D hydrodynamics simulations of core convection in supermassive main-sequence stars
Simon Blouin, Huaqing Mao, Tyrone E. Woods +3
Supermassive stars are Population III stars with masses exceeding that could be the progenitors of the first supermassive black holes. Their interiors are in a re…
3D hydrodynamics simulations of internal gravity waves in red giant branch stars
Simon Blouin, Huaqing Mao, Falk Herwig +3
We present the first 3D hydrodynamics simulations of the excitation and propagation of internal gravity waves (IGWs) in the radiative interiors of low-mass stars on the red giant b…
Distillation of Fe in Ultramassive O-Ne White Dwarfs
Matthew E. Caplan, Simon Blouin, Ian F. Freeman
When white dwarfs freeze the plasma mixtures inside them undergo separation processes which can produce radical changes in the composition profile of the star. The abundance of neu…
3D hydrodynamic simulations of massive main-sequence stars II. Convective excitation and spectra of internal gravity waves
William Thompson, Falk Herwig, Paul R. Woodward +4
Recent photometric observations of massive stars have identified a low-frequency power excess which appears as stochastic low-frequency variability in light curve observations. We…
3D hydrodynamic simulations of massive main-sequence stars. I. Dynamics and mixing of convection and internal gravity waves
Falk Herwig, Paul R. Woodward, Huaqing Mao +6
We performed 3D hydrodynamic simulations of the inner radial extent of a star in the early phase of the main sequence and investigate core con…
