The Contribution of Starspots to the Lithium Spread in NGC 2264
Yan Luo, Gregory J. Herczeg, Min Fang +2
Star clusters with ages of a few Myr have a previously unexplained dispersion in the lithium equivalent widths. In this work, we show that much of the lithium spread of the young c…
HRMOS: A High-Resolution Multi-Object Spectrograph for the VLT
Laura Magrini, Thomas Bensby, Sofia Randich +174
This White Paper presents the scientific rationale and instrument concept for HRMOS (High-Resolution Multi-Object Spectrograph), a next-generation instrument proposed for the ESO V…
Mock Observations for the CSST Mission: Main Surveys -- the Mock Catalogue
Cheng-Liang Wei, Yu Luo, Hao Tian +17
The Chinese Space Station Survey Telescope (CSST) is a flagship space mission, designed to carry out a large-area sky survey to explore the nature of dark matter and dark energy in…
Alien Type Ia supernovae from the Milky Way merger history and one possible candidate: Kepler's supernova
Wenlang He, Ping Zhou, Eda Gjergo +1
The Milky Way is a dynamic and evolving system shaped by numerous merger events throughout its history. These mergers bring stars with kinematic and dynamic properties differing fr…
Optical spectroscopic signatures of the red giant evolutionary state
Ella Xi Wang, Melissa Ness, Thomas Nordlander +17
Modern spectroscopic surveys output large data volumes. Theoretical models provide a means to transform the information encoded in these data to measurements of physical stellar pr…
Multiple generation star formation in Cepheus Flare
Fan Wang, Min Fang, Xiaoting Fu +8
We present an analysis of the young stellar moving group ASCC 127 using Gaia DR3 data, significantly expanding its membership to 3,971 stars -- double the number identified in prev…
Nearby open clusters with tidal features: golden sample selection and 3D structure
Ming Xu, Xiaoting Fu, Yang Chen +5
Open clusters offer unique opportunities to study stellar dynamics and evolution under the influence of their internal gravity, the Milky Way's gravitational field, and the interac…
Revisiting open clusters within 200 pc in the solar neighbourhood with Gaia DR3
Penghui Liu, Min Fang, Yue-Lin Sming Tsai +3
In this study, we develop a membership identification method and apply it for 30 open clusters (OCs) within 200 pc of the Sun using astrometric data of Gaia DR3. By accounting for…
The Magnified Waltz: Simulating Light Curves of Binary Stars Passing through Micro-Caustics in Strong Lensing Galaxy Clusters
Wenwen Zheng, Xiaoting Fu, Yang Chen +5
Individual stars located near the caustics of galaxy clusters can undergo extreme magnification when crossing micro-caustics, rendering them observable even at cosmological distanc…
Empirical color correction to MIST and PARSEC isochrones on Gaia BR-RP and G-RP with benchmark open clusters
Fan Wang, Min Fang, Xiaoting Fu +8
Recent literature reports a color deviation between observed Gaia color-magnitude diagrams (CMDs) and theoretical model isochrone predictions, particularly in the very low-mass reg…
First detection of CO isotopologues in a high-redshift main-sequence galaxy: evidence of a top-heavy stellar initial mass function
Ziyi Guo, Zhi-Yu Zhang, Zhiqiang Yan +5
Recent observations and theories have presented a strong challenge to the universality of the stellar initial mass function (IMF) in extreme environments. A notable example has bee…
Stellar population astrophysics (SPA) with the TNG: Measurement of the He I 10830Å line in the open cluster Stock 2
Mingjie Jian, Xiaoting Fu, Noriyuki Matsunaga +10
The precise measurement of stellar abundances plays a pivotal role in providing constraints on the chemical evolution of the Galaxy. However, before spectral lines can be employed…
Open Cluster Dynamics under the Influence of Outflow-Ambient Interactions
Muxin Liu, Lile Wang, Xiaoting Fu +1
Stars with outflows impinging on ambient gas experience accelerations due to the gravitational feedback from the interaction morphology between the outflow and the ambient gas. Suc…
