A Tale of Two Disks: Mapping the Milky Way with the Final Data Release of APOGEE
Julie Imig, Cathryn Price, Jon A. Holtzman +24
We present new maps of the Milky Way disk showing the distribution of metallicity ([Fe/H]), -element abundances ([Mg/Fe]), and stellar age, using a sample of 66,496 red giant st…
TESS Stellar Rotation up to 80 days in the Southern Continuous Viewing Zone
Zachary R. Claytor, Jennifer L. van Saders, Lyra Cao +3
The TESS mission delivers time-series photometry for millions of stars across the sky, offering a probe into stellar astrophysics, including rotation, on a population scale. Howeve…
Standardized Luminosity of the Tip of the Red Giant Branch utilizing Multiple Fields in NGC 4258 and the CATs Algorithm
Siyang Li, Adam G. Riess, Dan Scolnic +6
The Tip of the Red Giant Branch provides a luminous standard candle for calibrating distance ladders that reach Type Ia supernova (SN Ia) hosts. However, recent work reveals that t…
The APO-K2 Catalog. I. 7,673 Red Giants with Fundamental Stellar Parameters from APOGEE DR17 Spectroscopy and K2-GAP Asteroseismology
Jessica Schonhut-Stasik, Joel C. Zinn, Keivan G. Stassun +13
We present a catalog of fundamental stellar properties for 7,673 evolved stars, including stellar radii and masses, determined from the combination of spectroscopic observations fr…
CATS: The Hubble Constant from Standardized TRGB and Type Ia Supernova Measurements
D. Scolnic, A. G. Riess, J. Wu +7
The Tip of the Red Giant Branch (TRGB) provides a luminous standard candle for constructing distance ladders to measure the Hubble constant. In practice its measurements via edge-d…
Metallicity Gradient of Barred Galaxies with TYPHOON
Qian-Hui Chen, Kathryn Grasha, Andrew J. Battisti +5
Bars play an important role in mixing material in the inner regions of galaxies and stimulating radial migration. Previous observations have found evidence for the impact of a bar…
