The Stagger Code for Accurate and Efficient, Radiation-Coupled MHD Simulations
Robert F. Stein, Åke Nordlund, Remo Collet +1
We describe the Stagger Code for simulations of magneto-hydrodynamic (MHD) systems. This is a modular code with a variety of physics modules that will let the user run simulations…
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…
The solar carbon, nitrogen, and oxygen abundances from a 3D LTE analysis of molecular lines
A. M. Amarsi, N. Grevesse, M. Asplund +1
Carbon, nitrogen, and oxygen are the fourth, sixth, and third most abundant elements in the Sun. Their abundances remain hotly debated due to the so-called solar modelling problem…
The signature of granulation in a solar power spectrum as seen with COBOLD
Mia S. Lundkvist, Hans-Günter Ludwig, Remo Collet +1
The granulation background seen in the power spectrum of a solar-like oscillator poses a serious challenge for extracting precise and detailed information about the stellar oscilla…
Sun-like Oscillations in the Population II giant HD 122563
Orlagh Creevey, Frédéric Thévenin, Frank Grundahl +8
We have been monitoring the metal-poor Population II giant, HD 122563, for radial velocity variations since 2016 using the SONG telescope on Tenerife. We have detected the global s…
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…
