The Stellar Abundances and Galactic Evolution Survey (SAGES). V. The First Data Release of the DDO51 Band
Qiqian Zhang, Zhou Fan, Gang Zhao +20
We present the first public data release of DDO51 band from the Stellar Abundances and Galactic Evolution Survey (SAGES), based on Nanshan One-meter Wide-field Telescope (NOWT) obs…
Measurement of the Orbital Parameters, Spin and Spectral Evolution During the Main High State of Her X-1 with Insight-HXMT
Wen Yang, Wei Wang, Qianhan Zhou
Based on Insight-HXMT observations, we present a detailed timing analysis and spectral evolution of a complete Main High state for Her X-1 in February 2020. We determine an accurat…
Particle Acceleration in Cassiopeia A Revealed by Broadband High-Energy Spectrum
Bo-Tao Li, Wei Wang, Zhuo Li
Recently, the GeV--sub-PeV spectrum of supernova remnant (SNR) Cassiopeia A (Cas A), one of the youngest and most well-studied SNRs in our Galaxy, has been updated by observations…
High-resolution spectroscopic atmospheric studies of 5 hot Jupiters across the edge of the Neptune desert
Zewen Jiang, Wei Wang, Shumei Jia +6
Hot Jupiters (HJs), especially the Ultra-Hot Jupiters (UHJs), are ideal targets for robust atmospheric characterization, thanks to their high equilibrium temperatures and large atm…
Different polarized components of the quasar 3C 286 revealed by FAST
Pengfu Tian, Xiao Chen, Wen Yang +1
3C 286, a well-known radio calibrator, exhibits the stability in both of total flux density (FD) and polarization parameters. However, its stable and luminous interstellar radio si…
Polarized quasi-periodic oscillations reveal kink instability in magnetized jets of black holes
Jiashi Chen, Pengfu Tian, Wei Wang
The dynamics and instability of the magnetized jets connected to jet acceleration are complicated and are not yet well understood. Quasi-periodic oscillations (QPOs) as special tim…
