Progress in Studies of High Velocity Type Ia supernova SN 2017hpa

Type Ia supernovae (SNe Ia) are widely believed to originate from thermonuclear runaway explosions of carbon-oxygen (CO) white dwarfs (WDs) in binary systems, and their essentially identical peak luminosities make them indicators of extr...

Discovery Plasma Lensing in A Black Widow Pulsar

Black Widow ( BW ) and Rdebacks ( RB ) are an interesting subset of the pulsar population , and they jointly known as the spider pulsar system , which comprises a millisecond pulsar with a low-mass companion in short .Our results suggest...Using the Five-hundred-meter Aperture Spherical radio Telescope (FAST), a research team led by Dr. WANG Shuangqiang from the pulsar research group at the Xinjiang Astronomical Observatory（XAO) of the Chinese Academy of Sciences discove...

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...
