A Tale of Two Origins: In-Situ versus Accreted Nitrogen-Rich Field Stars in the MW
Yi Qiao, Baitian Tang, José G. Fernández-Trincado +14
Spectroscopic surveys have identified significant numbers of metal-poor nitrogen-rich (N-rich) field stars. These stars are strong candidates for escapees from globular clusters (G…
Semi-supervised Classification for Noisy Functional Data with Application to Astronomical Spectra
Ruoxu Tan, Mingjie Jian, Yiming Zang
Despite its extensive development for multivariate data, semi-supervised learning remains underdeveloped for functional data, especially under discrete and noisy observations. We d…
Abundance Analysis of Chemically Depleted Post-AGB/Post-RGB Binaries with Faint Discs
Maksym Mohorian, Devika Kamath, Meghna Menon +4
Post-AGB and post-RGB binaries with stable circumbinary discs provide key insights into late stellar and disc evolution, revealing how binary interactions shape disc structure and…
Differentiable Stellar Atmospheres with Physics-Informed Neural Networks
Jiadong Li, Mingjie Jian, Yuan-Sen Ting +1
We present Kurucz-a1, a physics-informed neural network (PINN) that emulates 1D stellar atmosphere models under Local Thermodynamic Equilibrium (LTE), addressing a critical bottlen…
Tianyu: search for the second solar system and explore the dynamic universe
Fabo Feng, Yicheng Rui, Zhimao Du +32
Giant planets like Jupiter and Saturn, play important roles in the formation and habitability of Earth-like planets. The detection of solar system analogs that have multiple cold g…
The Present-Day Mass Function of Star Clusters in the Solar Neighborhood
Xiaoying Pang, Siqi Liao, Jiadong Li +5
This work analyses the present-day mass function (PDMF) of 93~star clusters utilizing Gaia DR3 data, with membership determined by the StarGo machine learning algorithm. The impact…
