zoomies: A Tool to Infer Stellar Age from Vertical Action in Gaia Data
The Astrophysical JournalStellar age measurements are fundamental to understanding a wide range of astronomical processes, including Galactic dynamics, stellar evolution, and planetary system formation. However, extracting age information from main-sequence stars is complicated,

Improvements in stellar ages in the era of Gaia
, 2019 We present estimates of the distances; ages and masses for nearly 5;5 million stars from public spectroscopic surveys. To derive these estimates we use Gaia DR2 parallax values; spectroscopic parameters as well as infra-red photometry. These estimates were obtained with the third version of the Unified tool to estimate Distances; Ages; and Masses ...

Model Choice Matters for Age Inference on the Red Giant Branch
The Astrophysical JournalGalactic archaeology relies on accurate stellar parameters to reconstruct the Galaxy's history, including information on stellar ages. While the precision of data has improved significantly in recent years, stellar models used for age inference have not ...

[C/N] Ages and Extra Mixing for [Fe/H] < −0.5: Insights from the LMC and SMC
The Astrophysical JournalThe [C/N]–age relation has become a powerful tool for reconstructing the formation history of the Milky Way (MW), providing the largest age sample for field giant stars.

The Astrophysical JournalWithin the molecular clouds of the Camelopardis OB1 (Cam OB1) association exists a region previously noted as one subgroup. However, bulk clustering from Gaia astrometry has recently shown three distinctive kinematically coherent groups, all found in a ...

X-Ray Emission and Stellar Ages of Sun-like Stars
The Astrophysical JournalWe present an analysis of XMM-Newton and Chandra observations of 85 nearby main-sequence FGK stars with age estimates ranging from 0.2 to 12 Gyr. We measure quiescent 0.3–10 keV luminosities, variability metrics, and multitemperature thermal plasma ...
