Calibrating the Cepheid Period--Wesenheit Relation in the Gaia Bands using Galactic Open Cluster Cepheids
Zehao Lin, Ye Xu, Chaojie Hao +3
Establishing the period--Wesenheit relation requires independent and accurate distance measurements of classical Cepheids (DCEPs). The precise distance provided by an associated op…
The Effect of Light Deflection by Solar System Objects on High-Precision SKA Astrometry
Yingjie Li, Ye Xu, Shaibo Bian +4
We have computed the deflection angles caused by 195 objects in the solar system, including 177 satellites and eight asteroids. Twenty-one satellites and six asteroids can bend lig…
Dependence of Molecular Cloud Samples on Angular Resolution, Sensitivity, and Algorithms
Qing-Zeng Yan, Ji Yang, Yang Su +6
In this work, we investigate the observational and algorithmic effects on molecular cloud samples identified from position-position-velocity (PPV) space. By smoothing and cutting o…
Local Spiral Structure Traced by Red Clump Stars
Zehao Lin, Ye Xu, Ligang Hou +5
Using the cross-matched data of Gaia EDR3 and the 2MASS Point Source Catalog, a sample of RC stars with parallax accuracies better than 20% is identified and used to reveal the nea…
