Revisiting the exoplanet radius valley with host stars from SWEET-Cat
Juma Kamulali, Vardan Adibekyan, Benard Nsamba +7
The radius valley,a deficit of planets near 2 , was observed among exoplanets of radius 5 with periods 100 days by NASA's…
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…
Comparison of Three Methods for Triggering Core-collapse Supernova Explosions in Spherical Symmetry
Liliya Imasheva, H. -Thomas Janka, Achim Weiss
Despite the three-dimensional nature of core-collapse supernovae (CCSNe), simulations in spherical symmetry (1D) play an important role to study large model sets for the progenitor…
MAISTEP -- a new grid-based machine learning tool for inferring stellar parameters I. Ages of giant-planet host stars
Juma Kamulali, Benard Nsamba, Vardan Adibekyan +3
Our understanding of exoplanet demographics partly depends on their corresponding host star parameters. With the majority of exoplanet-host stars having only atmospheric constraint…
Uniform characterisation of an ensemble of main-sequence benchmark stars: effect of Gaia-based data on grid search models
Benard Nsamba, Achim Weiss, Juma Kamulali
The inference of stellar parameters (such as radius and mass) through asteroseismic forward modelling depends on the number, accuracy, and precision of seismic and atmospheric cons…
