ChronoFlow: A Data-Driven Model for Gyrochronology
Phil R. Van-Lane, Joshua S. Speagle, Gwendolyn M. Eadie +6
Gyrochronology is a technique for constraining stellar ages using rotation periods, which change over a star's main sequence lifetime due to magnetic braking. This technique shows…
The temporal and spatial variations of lithium abundance in the Galactic disc
Tiancheng Sun, Shaolan Bi, Xunzhou Chen +7
This study investigates the temporal and spatial variations in lithium abundance within the Milky Way using a sample of 22,034 main-sequence turn-off (MSTO) stars and subgiants, ch…
When LAMOST meets Gaia DR3 Exploring the metallicity of open clusters
R. Zhang, Guo-Jian Wang, Yuxi +9
Context. Open clusters (OCs) are valuable probes of stellar population characteristics. Their age and metallicity provide insights into the chemical enrichment history of the Milky…
The Dog that Didn't Bark: Non-Variable Field Stars in the RR Lyrae Instability Strip
Yuxi Lu, Cecilia Mateu, K. Z. Stanek
RR Lyrae stars (RRLs) are easy to identify thanks to their large photometric variation and short periods. All stars in the RRL instability strip are pulsators is often a hidden ass…
On Convective Turnover Times and Dynamos In Low-Mass Stars
Seth Gossage, Rocio Kiman, Kristina Monsch +7
The relationship between magnetic activity and Rossby number is one way through which stellar dynamos can be understood. Using measured rotation rates and X-ray to bolometric lumin…
The Milky Way Radial Metallicity Gradient as an Equilibrium Phenomenon: Why Old Stars are Metal-Rich
James W. Johnson, David H. Weinberg, Guillermo A. Blanc +12
Metallicities of both gas and stars decline toward large radii in spiral galaxies, a trend known as the radial metallicity gradient. We quantify the evolution of the metallicity gr…
Evidence of Truly Young high- Dwarf Stars
Yuxi Lu, Isabel L. Colman, Maryum Sayeed +14
The existence of high- stars with inferred ages < 6 Gyr has been confirmed recently with large spectroscopic and photometric surveys. However, stellar mergers or binary interact…
The impact of stellar metallicity on rotation and activity evolution in the Kepler field using gyro-kinematic ages
Victor See, Yuxi, Lu +2
In recent years, there has been a push to understand how chemical composition affects the magnetic activity levels of main sequence low-mass stars. Results indicate that more metal…
zoomies: A tool to infer stellar age from vertical action in Gaia data
Sheila Sagear, Adrian M. Price-Whelan, Sarah Ballard +4
Stellar age measurements are fundamental to understanding a wide range of astronomical processes, including Galactic dynamics, stellar evolution, and planetary system formation. Ho…
Stellar Mergers or Truly Young? Intermediate-Age Stars on Highly-Radial Orbits in the Milky Way's Stellar Halo
Danny Horta, Yuxi, Lu +3
Reconstructing the mass assembly history of the Milky Way relies on obtaining detailed measurements of the properties of many stars in the Galaxy, especially in the stellar halo. O…
Methods for the detection of stellar rotation periods in individual TESS sectors and results from the Prime mission
Isabel L. Colman, Ruth Angus, Trevor David +3
For ongoing studies of the role of rotation in stellar evolution, we require large catalogs of rotation periods for testing and refining gyrochronology. While there is a wealth of…
