      Statistical analysis of solar radio fiber bursts and relations with flares
      The dynamic spectrum of solar radio bursts is commonly characterized by various fine structures (FSs). These spectral FSs mainly depend on the energetic particles, on the magnetic field in the source region, and on the detailed flaring p...

      Investigation of bright pulse emission from PSR B0031-07
      Pulsars are highly magnetized and rapidly rotating neutron stars, providing us an opportunity to explore physics under extreme conditions. The intensity variation of pulsar emission is erratic on a broad range of timescales from nanoseco...

      Spectroscopic and photometric analysis of the eclipsing binary HIP 7666 with δ Scuti pulsations
      We carried out new multi-color photometric and spectroscopic observations with five telescopes (NOWT, XL85cm, SPM84cm, YAO2.4m, NAO2.16m, and SPM2.12m) for eclipsing binary HIP 7666, respectively. The radial velocity curves are presented...

      Investigating Cold Dust Properties of 12 Nearby Dwarf Irregular Galaxies by Hierarchical Bayesian Spectral Energy Distribution Fitting
      Recently, the hierarchical Bayesian approach is introduced to fit the MBB model (Kelly et al. 2012; Juvela et al. 2013; Lamperti et al. 2019), which could reduce the degeneracy between T and β greatly, and so improve the SED fitting res...

      A Low-amplitude Double-mode Delta Scuti Star with Amplitude Modulation
      The Delta Scuti stars show rich oscillation modes in observations, both of radial and non-radial oscillation are detected. Different modes show different propagation behaviors in the star and reflect different properties of the stellar s...

      The Reconstruction of Dark Energy by the Ridge Regression Approach
      Since cosmic acceleration was first discovered in 1998 by Riess et al., physicists have predicted the existence of dark energy to explain the accelerating expansion of the universe. Meanwhile, dark energy theory can be used to explain th...
