The Variation of the Galaxy-Wide IMF for Low-Mass Stars: Modeling and Observational Insights
Zhiqiang Yan, Jiadong Li, Pavel Kroupa +3
The Stellar Initial Mass Function (IMF) characterizes the mass distribution of newly formed stars in various cosmic environments, serving as a fundamental assumption in astrophysic…
CURLING - I. The Influence of Point-like Image Approximation on the Outcomes of Cluster Strong Lens Modeling
Yushan Xie, Huanyuan Shan, Nan Li +11
Cluster-scale strong lensing is a powerful tool for exploring the properties of dark matter and constraining cosmological models. However, due to the complex parameter space, pixel…
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…
The Stellar "Snake" -- II: The Mass Function
Xiang-Ming Yang, Sarah A. Bird, Jiadong Li +8
We present a comprehensive investigation on the mass function (MF) of a snake-like stellar structure in the solar neighbourhood, building on our previous discovery. To ensure the r…
