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…
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…
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…
Stellar population astrophysics (SPA) with the TNG: Measurement of the He I 10830Ã 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…
