Stellar Birth Radii in the LMC: Insights into Chemodynamics, Radial Migration, and Star Formation Across the Disk
Yuxi Lu, Bethany Garver, David L. Nidever +4
The LMC and SMC are interacting dwarf galaxies that offer a valuable testbed for studying the effects of galactic mergers. We investigate the chemodynamic history of the LMC in the…
Spectroscopic Follow-up of Young High- Dwarf Star Candidates: Still Likely Genuinely Young
Yuxi Lu, Catherine Manea, Maryum Sayeed +9
The question of whether genuinely young high- stars exist has been discussed for over a decade since their discovery from asteroseismology of giant stars as it is challenging to…
C3PO V: Comoving stellar pairs indicate rotational spin-down drives the main-sequence Li-Dip
Qinghui Sun, Yuan-Sen Ting, Barbara J. Anthony-Twarog +4
The lithium-dip observed in mid-F dwarfs remains a long-standing challenge for stellar evolution models. We present high-precision stellar parameters and A(Li) for 22 new comoving…
Sloan Digital Sky Survey-V: Pioneering Panoptic Spectroscopy
Juna A. Kollmeier, Hans-Walter Rix, Conny Aerts +217
The Sloan Digital Sky Survey-V (SDSS-V) is pioneering panoptic spectroscopy: it is the first all-sky, multi-epoch, optical-to-infrared spectroscopic survey. SDSS-V is mapping the s…
Causal Discovery of Latent Variables in Galactic Archaeology
Zehao Jin, Yuxi Lu, Yuan-Sen Ting +2
Galactic archaeology--the study of stellar migration histories--provides insights into galaxy formation and evolution. However, establishing causal relationships between observable…
Anchoring Stellar Age Indicators: A Cross-Calibration of [C/N] and Gyrochronology Ages via the Age-Velocity-Dispersion Relation
Yuxi Lu, Marc H. Pinsonneault, Yuan-Sen Ting +4
Determining stellar ages is challenging, as it depends on other stellar parameters in a non-linear way and often relies on stellar evolution models to infer the underlying relation…
Measuring Long Stellar Rotation Periods (>10 days) from TESS FFI Light Curves is Possible: An Investigation Using TESS and ZTF
Soichiro Hattori, Ruth Angus, Daniel Foreman-Mackey +3
The rotation period of a star is an important quantity that provides insight into its structure and state. For stars with surface features like starspots, their periods can be infe…
N-body simulations of the Self-Confinement of Viscous Self-Gravitating Narrow Eccentric Planetary Ringlets
Joseph M. Hahn, Douglas P. Hamilton, Thomas Rimlinger +1
Narrow eccentric planetary ringlets have sharp edges, sizable eccentricity gradients, and a confinement mechanism that prevents radial spreading due to ring viscosity. Most propose…
Trials and Tribulations of Chemodynamical Tagging: Investigating the Recovery of Open Clusters in the Gaia DR3-GALAH DR4 Catalog
Nicholas A. Barth, David Mendez, Rana Ezzeddine +5
Chemodynamical tagging has been suggested as a powerful tool to trace stars back to their birth clusters. However, the efficacy of chemodynamical tagging as a means to recover indi…
Observational Constraints of Radial Migration in the Galactic Disc Driven by the Slowing Bar
HanYuan Zhang, Vasily Belokurov, N. Wyn Evans +7
Radial migration is an important dynamical effect that has reshaped the Galactic disc, but its origin has yet to be elucidated. In this work, we present evidence that resonant drag…
StarFlow: Leveraging Normalizing Flows for Stellar Age Estimation in SDSS-V DR19
Alexander Stone-Martinez, Jon A. Holtzman, Yuxi +6
Understanding the ages of stars is crucial for unraveling the formation history and evolution of our Galaxy. Traditional methods for estimating stellar ages from spectroscopic data…
A Data-Driven M Dwarf Model and Detailed Abundances for 17,000 M Dwarfs in SDSS-V
Aida Behmard, Melissa K. Ness, Andrew R. Casey +6
The cool temperatures of M dwarf atmospheres enable complex molecular chemistry, making robust characterization of M dwarf compositions a long-standing challenge. Recent modificati…
Exoplanet Occurrence Rate with Age for FGK Stars in Kepler
Maryum Sayeed, Ruth Angus, Travis Berger +5
We measure exoplanet occurrence rate as a function of isochrone and gyrochronology ages using confirmed and candidate planets identified in Q1-17 DR25 Kepler data. We employ Kepler…
Testing the Rossby Paradigm: Weakened Magnetic Braking in early K-type Stars
Travis S. Metcalfe, Pascal Petit, Jennifer L. van Saders +12
There is an intricate relationship between the organization of large-scale magnetic fields by a stellar dynamo and the rate of angular momentum loss due to magnetized stellar winds…
