Validating full-spectrum fitting with a synthetic integral-field spectroscopic observation of the Milky Way
Zixian Wang, Michael R. Hayden, Sanjib Sharma +5
Ongoing deep IFS observations of disk galaxies provide opportunities for comparison with the Milky Way (MW) to understand galaxy evolution. However, such comparisons are marred by…
Asteroseismology with the Roman Galactic Bulge Time-Domain Survey
Daniel Huber, Marc Pinsonneault, Paul Beck +24
Asteroseismology has transformed stellar astrophysics. Red giant asteroseismology is a prime example, with oscillation periods and amplitudes that are readily detectable with time-…
RomAndromeda: The Roman Survey of the Andromeda Halo
Arjun Dey, Joan Najita, Carrie Filion +50
As our nearest large neighbor, the Andromeda Galaxy provides a unique laboratory for investigating galaxy formation and the distribution and substructure properties of dark matter…
CN and CO Features: Key Indicators of Red Giant Evolutionary Phase in Moderate-Resolution X-Shooter Spectra
Kirsten A. Banks, Chantel Y. Y. Ho, Sarah L. Martell +6
Data-driven analysis methods can help to infer physical properties of red giant stars where "gold-standard" asteroseismic data are not available. The study of optical and infrared…
Extension of the Asfgrid for correcting asteroseismic large frequency separations
D. Stello, S. Sharma
The asteroseismic scaling relation, dnu~rho^{0.5}, linking a star's large frequency separation, dnu, and its mean density, rho, is not exact. Yet, it provides a very useful way to…
