Type I X-ray bursts' spectra and fuel composition from the atoll and transient source 4U 173022
Yongqi Lu, Zhaosheng Li, Yuanyue Pan +8
NICER observed two outbursts from the neutron star low-mass X-ray binary 4U~173022 in 2021 and 2022, which showed a similar spectral evolution in the hardness-intensity diagram.…
Dynamical Origin for the Collinder 132-Gulliver 21 Stream: A Mixture of three Co-Moving Populations with an Age Difference of 250 Myr
Xiaoying Pang, Yuqian Li, Shih-Yun Tang +6
We use Gaia DR3 data to study the Collinder 132-Gulliver 21 region via the machine learning algorithm StarGO, and find eight subgroups of stars (ASCC 32, Collinder 132 gp 1--6, Gul…
The Carnegie-Irvine Galaxy Survey. X. Bulges in Stellar Mass-based Scaling Relations
Hua Gao, Luis C. Ho, Zhao-Yu Li
We measure optical colors for the bulges of 312 disk galaxies from the Carnegie-Irvine Galaxy Survey and convert their previously available -band structural parameters to stella…
Metallicity Properties of the Galactic Bulge Stars Near and Far: Expectations from the Auriga Simulation
Bin-Hui Chen, Zhao-Yu Li
Using the high resolution Milky Way-like model from Auriga simulation we study the chemical properties of the Galactic bulge, focusing on the metallicity difference between stars o…
Discovery of a 584.65 Hz Burst Oscillation in the Low Mass X-Ray Binary 4U 1730--22
Zhaosheng Li, Wenhui Yu, Yongqi Lu +2
Type-I X-ray burst oscillations are powered by thermonuclear released on the neutron star (NS) surface in low mass X-ray binaries (LMXBs), where the burst oscillation frequencies a…
NICER observations of the evidence of Poynting-Robertson drag and disk reflection during type I X-ray bursts from 4U 1636536
Guoying Zhao, Zhaosheng Li, Yuanyue Pan +4
Type I X-ray bursts are the result of an unstable thermonuclear burning of accreting matter on the neutron star (NS) surface. The quick release of energetic X-ray photons during su…
