Ordered Diffusion Kernels
Jack H. Soulsby, Andreas C. S. Jørgensen, Atiyo Ghosh +1
We introduce Ordered Diffusion Kernels (ODKs), a novel class of local kernels that can approximate the infinitesimal generator of an arbitrary Itô Stochastic Differential Equation…
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…
Data-driven spatio-temporal modelling of glioblastoma
Andreas Christ Sølvsten Jørgensen, Ciaran Scott Hill, Marc Sturrock +7
Mathematical oncology provides unique and invaluable insights into tumour growth on both the microscopic and macroscopic levels. This review presents state-of-the-art modelling tec…
Prospects for Galactic and stellar astrophysics with asteroseismology of giant stars in the Continuous Viewing Zones and beyond
J. Ted Mackereth, Andrea Miglio, Yvonne Elsworth +30
The NASA- mission presents a treasure trove for understanding the stars it observes and the Milky Way, in which they reside. We present a first look at the prospects for…
On the impact of the structural surface effect on global stellar properties and asteroseismic analyses
Andreas Christ Sølvsten Jørgensen, Josefina Montalbán, George C. Angelou +6
In a series of papers, we have recently demonstrated that it is possible to construct stellar structure models that robustly mimic the stratification of multi-dimensional radiative…
Investigating surface correction relations for RGB stars
Andreas Christ Sølvsten Jørgensen, Josefina Montalbán, Andrea Miglio +7
State-of-the-art stellar structure and evolution codes fail to adequately describe turbulent convection. For stars with convective envelopes, such as red giants, this leads to an i…
Coupling 1D stellar evolution with 3D-hydrodynamical simulations on-the-fly II: Stellar Evolution and Asteroseismic Applications
Jakob Rørsted Mosumgaard, Andreas Christ Sølvsten Jørgensen, Achim Weiss +2
Models of stellar structure and evolution are an indispensable tool in astrophysics, yet they are known to incorrectly reproduce the outer convective layers of stars. In the first…
Bayesian inference of stellar parameters based on 1D stellar models coupled with 3D envelopes
Andreas Christ Sølvsten Jørgensen, George C. Angelou
Stellar models utilising one-dimensional (1D), heuristic theories of convection fail to adequately describe the energy transport in superadiabatic layers. The improper modelling le…
Overcoming the structural surface effect with a realistic treatment of turbulent convection in 1D stellar models
Andreas Christ Sølvsten Jørgensen, Achim Weiss
State-of-the-art one-dimensional (1D) stellar evolution codes rely on simplifying assumptions, such as mixing length theory, in order to describe superadiabatic convection. As a re…
Mending the structural surface effect of 1D stellar structure models with non-solar metallicities based on interpolated 3D envelopes
Andreas Christ Sølvsten Jørgensen, Achim Weiss, George Angelou +1
1D stellar evolution codes employ rudimentary treatments of turbulent convection. For stars with convective envelopes, this leads to systematic errors in the predicted oscillation…
Addressing the acoustic tachocline anomaly and the lithium depletion problem at the same time
Andreas Christ Sølvsten Jørgensen, Achim Weiss
Current standard solar models neither account properly for the photospheric lithium abundance nor reproduce the inferred solar sound speed profile. Diffusive overshooting at the ba…
A Semi-Analytical Computation of the Theoretical Uncertainties of the Solar Neutrino Flux
Andreas Christ Sølvsten Jørgensen, Jørgen Christensen-Dalsgaard
We present a comparison between Monte Carlo simulations and a semi-analytical approach that reproduces the theoretical probability distribution functions of the solar neutrino flux…
Coupling 1D stellar evolution with 3D-hydrodynamical simulations on-the-fly I: A New Standard Solar Model
Andreas Christ Sølvsten Jørgensen, Jakob Rørsted Mosumgaard, Achim Weiss +2
Standard 1D stellar evolution models do not correctly reproduce the structure of the outermost layers of stars with convective envelopes. This has been a long-standing problem in s…
Theoretical oscillation frequencies for solar-type dwarfs from stellar models with -atmospheres
Andreas Christ Sølvsten Jørgensen, Achim Weiss, Jakob Rørsted Mosumgaard +2
We present a new method for replacing the outermost layers of stellar models with interpolated atmospheres based on results from 3D simulations, in order to correct for structural…
