EncoTESS: Age-Sensitive Encodings from Raw TESS Light Curves

Phil R. Van-Lane, Joshua S. Speagle, Ryan Cloutier +3

Main sequence stars of spectral types late F through M exhibit systematic variability in photometric light curves, particularly when they are young. Rotational modulation of starsp…

Deriving Stellar Properties, Distances, and Reddenings using Photometry and Astrometry with BRUTUS

Joshua S. Speagle, Catherine Zucker, Angus Beane +18

We present brutus, an open source Python package for quickly deriving stellar properties, distances, and reddenings to stars based on grids of stellar models constrained by photome…

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…

Should zeros count? Modeling the galaxy-globular cluster scaling relation with(out) zero-inflated count models

Samantha C. Berek, Gwendolyn M. Eadie, Joshua S. Speagle +1

The scaling relation between the size of a galaxy's globular cluster (GC) population () and the galaxy's stellar mass () is usually described with a continuous, linear…

Improving Harmonic Analysis using Multitapering: Precise frequency estimation of stellar oscillations using the harmonic F-test

Aarya A. Patil, Gwendolyn M. Eadie, Joshua S. Speagle +1

In Patil et. al 2024a, we developed a multitaper power spectrum estimation method, mtNUFFT, for analyzing time-series with quasi-regular spacing, and showed that it not only improv…

The Power of High Precision Broadband Photometry: Tracing the Milky Way Density Profile with Blue Horizontal Branch stars in the Dark Energy Survey

Fengqing Yu, Ting S. Li, Joshua S. Speagle +9

Blue Horizontal Branch (BHB) stars, excellent distant tracers for probing the Milky Way's halo density profile, are distinguished in the vs color space from ano…
