Mapping the Milky Way's stellar halo with 2D data
Anda Chen, Zhigang Li, Yougang Wang +3
We propose a new method for measuring the spatial density distribution of the stellar halo of the Milky Way. Our method is based on a pairwise statistic of the distribution of star…
Making hot Jupiters in stellar clusters II: efficient formation in binary systems
Daohai Li, Alexander J. Mustill, Melvyn B. Davies +1
Observations suggested that the occurrence rate of hot Jupiters (HJs) in open clusters is largely consistent with the field () but in the binary-rich cluster M67, the rate…
Secular dynamics of stellar spin driven by planets inside Kozai-Lidov resonance
Hanlun Lei, Yan-Xiang Gong
In many exoplanetary systems with `hot Jupiters', it is observed that the spin axes of host stars are highly misaligned to planetary orbital axes. In this study, a possible channel…
Implications of the Stellar Mass Density of High- Massive Galaxies from JWST on Warm Dark Matter
Hengjie Lin, Yan Gong, Bin Yue +1
A significant excess of the stellar mass density at high redshift has been discovered from the early data release of James Webb Space Telescope (), and it may require a…
The distance to the Serpens South Cluster from H2O masers
Gisela N. Ortiz-Leon, Sergio A. Dzib, Laurent Loinard +3
In this Letter, we report Very Long Baseline Array observations of 22 GHz water masers toward the protostar CARMA-6, located at the center of the Serpens South young cluster. From…
Cross-Correlation Forecast of CSST Spectroscopic Galaxy and MeerKAT Neutral Hydrogen Intensity Mapping Surveys
Yuer Jiang, Yan Gong, Meng Zhang +6
Cross-correlating the data of neutral hydrogen (HI) 21cm intensity mapping with galaxy surveys is an effective method to extract astrophysical and cosmological information. In this…
