Coupling 1D stellar evolution with 3D-hydrodynamical simulations on-the-fly III: stellar evolution at different metallicities
Yixiao Zhou, Jakob L. Rørsted, Achim Weiss +10
A major weakness in one-dimensional (1D) stellar structure and evolution modeling is the simplified treatment of convection, which leads to erroneous near-surface stratification an…
Realistic Uncertainties for Fundamental Properties of Asteroseismic Red Giants and the Interplay Between Mixing Length, Metallicity and
Yaguang Li, Timothy R. Bedding, Daniel Huber +8
Asteroseismic modelling is a powerful way to derive stellar properties. However, the derived quantities are limited by built-in assumptions used in stellar models. This work presen…
An extended and refined grid of 3D STAGGER model atmospheres. Processed snapshots for stellar spectroscopy
Luisa F. Rodríguez Díaz, Cis Lagae, Anish M. Amarsi +6
Context: Traditional one-dimensional (1D) hydrostatic model atmospheres introduce systematic modelling errors into spectroscopic analyses of FGK-type stars. Aims: We present an upd…
Does the scaling relation depend on metallicity? Insights from 3D convection simulations
Yixiao Zhou, Jørgen Christensen-Dalsgaard, Martin Asplund +4
Solar-like oscillations have been detected in thousands of stars thanks to modern space missions. These oscillations have been used to measure stellar masses and ages, which have b…
3D Stagger model atmospheres with FreeEOS I. Exploring the impact of microphysics on the Sun
Yixiao Zhou, Anish M. Amarsi, Victor Aguirre Børsen-Koch +3
Three-dimensional radiation-hydrodynamics (3D RHD) simulations of stellar surface convection provide valuable insights into many problems in solar and stellar physics. However, alm…
Non-detection of Li in Spite plateau stars with ESPRESSO
E. X. Wang, T. Nordlander, M. Asplund +3
The detection of Li in Spite plateau stars contradicts the standard Big Bang nucleosynthesis prediction, known as the second cosmological lithium problem. We measure the isotop…
The relationship between photometric and spectroscopic oscillation amplitudes from 3D stellar atmosphere simulations
Yixiao Zhou, Thomas Nordlander, Luca Casagrande +5
We establish a quantitative relationship between photometric and spectroscopic detections of solar-like oscillations using ab initio, three-dimensional (3D), hydrodynamical numeric…
3D NLTE spectral line formation of lithium in late-type stars
E. Wang, T. Nordlander, M. Asplund +3
Accurately known stellar lithium abundances may be used to shed light on a variety of astrophysical phenomena such as Big Bang nucleosynthesis, radial migration, ages of stars and…
Convective Excitation and Damping of Solar-like Oscillations
Yixiao Zhou, Martin Asplund, Remo Collet +1
The last decade has seen a rapid development in asteroseismology thanks to the CoRoT and Kepler missions. With more detailed asteroseismic observations available, it is becoming po…
The amplitude of solar p-mode oscillations from three-dimensional convection simulations
Yixiao Zhou, Martin Asplund, Remo Collet
The amplitude of solar p-mode oscillations is governed by stochastic excitation and mode damping, both of which take place in the surface convection zone. However, the time-depende…
Equation of State Dependence of Nonlinear Mode-tide Coupling in Coalescing Binary Neutron Stars
Yixiao Zhou, Fan Zhang
Recently, an instability due to the nonlinear coupling of p-modes to g-modes in tidally deformed neutron stars in coalescing binaries has been studied in some detail. The result is…
