Testing the Breakdown of the Asteroseismic Scaling Relations in Luminous Red Giants
Published 2025-01-01“…We test the ${\nu }_{{\rm{\max }}}$ and Δ ν scaling relations separately, by using stars of known mass and radius in star clusters and the Milky Way's high- α sequence. We find evidence that the Δ ν scaling relation contributes to the observed breakdown in luminous giants more than the ${\nu }_{{\rm{\max }}}$ relation. …”

cogsworth: A Gala of COSMIC Proportions Combining Binary Stellar Evolution and Galactic Dynamics
Published 2025-01-01“…We provide a detailed explanation of the functionality of cogsworth and demonstrate its capabilities through a series of use cases: (1) we predict the spatial distribution of compact objects and runaways in both dwarf and Milky Way–like galaxies; (2) using a star cluster from a hydrodynamical simulation, we show how supernovae can change the orbits of stars in several ways; and (3) we predict the separation of disrupted binary stellar companions on the sky and create a synthetic Gaia color–magnitude diagram. …”

Calibrating the Color–Magnitude Relation of M Giants by Using Open Clusters
Published 2025-01-01“…M giants, with their distinctive properties such as high luminosity, serve as excellent indicators for mapping the structure of the Milky Way. The distance to distant M giants can be determined by using the color–magnitude relation (CMR), which is derived from color–magnitude diagrams of specific systems in previous studies. …”
