A seismic scaling relation for stellar age

2019-03-11 · Monthly Notices of the Royal Astronomical Society 2019 3 · Earl Patrick Bellinger

A simple solar scaling relation for estimating the ages of main-sequence stars from asteroseismic and spectroscopic data is developed. New seismic scaling relations for estimating mass and radius are presented as well, including a purely seismic radius scaling relation (i.e., no dependence on temperature). The relations show substantial improvement over the classical scaling relations and perform similarly well to grid-based modeling.

Flow-Based Generative Emulation of Grids of Stellar Evolutionary Models

2024-07-12 · Marc Hon, Yaguang Li, Joel Ong

We present a flow-based generative approach to emulate grids of stellar evolutionary models. By interpreting the input parameters and output properties of these models as multi-dimensional probability distributions, we t…

Stellar Age Compression Reshapes Interpretations of the Milky Way Thick-Disk Formation History

2026-05-11 · Zhipeng Zhang arxiv

The formation timescale of the Milky Way thick disk is one of the central debates in Galactic archaeology. The age-metallicity relation (AMR), formation timescale, and chemical evolution gradients are frequently used to …

Fundamental Parameters of Main-Sequence Stars in an Instant with Machine Learning

Inferring Asteroseismic Parameters from Short Observations Using Deep Learning: Application to TESS and K2 Red Giants

2026-05-08 · Nipun Ghanghas, Siddharth Dhanpal, Shravan Hanasoge, Praneeth Netrapalli 외 arxiv

Asteroseismology is the study of resonant oscillations of stars to infer their internal structure and dynamics. It is also a powerful tool for precisely determining stellar parameters such as mass, radius, surface gravit…

The Scaling Law in Stellar Light Curves

2024-05-27 · Jia-Shu Pan, Yuan-Sen Ting, Yang Huang, Jie Yu 외

Analyzing time series of fluxes from stars, known as stellar light curves, can reveal valuable information about stellar properties. However, most current methods rely on extracting summary statistics, and studies using …
