Asteroseismology of solar-like oscillators: emulating individual mode frequencies with a branching neural network
Owen J. Scutt, Guy R. Davies, Amalie Stokholm +6
Accurately measuring stellar ages and internal structures is challenging, but the inclusion of asteroseismic observables can substantially improve precision. However, the curse of…
Theoretical models for the Late Thermal Pulse in post-AGB stars: the case of DY Cen
Zhongyang Liu, C. Simon Jeffery, Xianfei Zhang +2
We present theoretical predictions of the born-again scenario for post-asymptotic giant-branch stars. An extensive model grid for born-again objects has been constructed, particula…
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…
Potential Impact of the Sagittarius Dwarf Galaxy on the Formation of Young O-rich Stars
Tiancheng Sun, Shaolan Bi, Xunzhou Chen +11
The Milky Way underwent significant transformations in its early history, characterised by violent mergers and satellite galaxy accretion. However, recent observations reveal notab…
