Constraining the Delay Time Distribution of the r- and s-Process from Stellar Ages at Solar Metallicity
Meng Zhang, Hans-Walter Rix
We present a new approach to constraining the delay time distribution (DTD) governing r- and s-process element production. Rather than using metallicity as a proxy for time, we wor…
Testing Chemical Tagging with LAMOST: Intrinsic Abundance Dispersion of Subgiant Stars in the Galactic Disk
Wu Yaqian, Xiang Maosheng, Zhao Gang +4
The scatter in elemental abundances among stars of similar age and metallicity reflects chemical inhomogeneity in their birth environments, making abundance scatter a key observabl…
SPURS: Evidence for Clumpy Neutral Envelopes and Ionized IGM Surrounding Little Red Dots in Abell 2744 from Ultra-Deep Rest-UV Spectroscopy
Mengtao Tang, Daniel P. Stark, Charlotte A. Mason +14
Rest-frame ultraviolet (UV) spectra of Little Red Dots (LRDs) often show Ly emission. Along with broad Balmer emission, LRDs are expected to produce broad Ly emission. Howeve…
PhDLspec: physical-prior embedded deep learning method for spectroscopic determination of stellar labels in high-dimensional parameter space
Tianmin Wu, Maosheng Xiang, Jianrong Shi +4
Unlocking the full physical information encoded in low-resolution spectra poses a significant challenge for astronomical survey analysis. Such a task demands modeling spectra and o…
