Inter-Correlation Between Sunspot Oscillations and Their Internal Structures
Libo Fu, Zizhan Zhu, Ding Yuan +3
Three- and five-minute oscillations are commonly found in any sunspot. As they are modulated by the internal thermal and magnetic structures of a sunspot, therehence, they could be…
Preflare very long-periodic pulsations observed in Halpha emission before the onset of a solar flare
Dong Li, Song Feng, Wei Su +1
Very long-periodic pulsations during preflare phases (preflare-VLPs) have been detected in the full-disk solar soft X-Ray (SXR) flux (see Tan et al. 2016). They may be regarded as…
Magnetic connectivity between the light bridge and penumbra in a sunspot
Song Feng, Yuhu Miao, Ding Yuan +2
A light bridge is a prominent structure commonly observed within a sunspot. Its presence usually triggers a wealth of dynamics in a sunspot, and has a lasting impact on sunspot evo…
Estimating red noise in quasi-periodic signals with MCMC-based Bayesian
Bo Liang, Yao Meng, Song Feng +1
Multi-parameter Bayesian inferences based on Markov chain Monte Carlo (MCMC) samples have been widely used to estimate red noise in solar period-periodic signals. To MCMC, proper p…
Propagating Slow Sausage Waves in a Sunspot Observed by the New Vacuum Solar Telescope
Song Feng, Zheng Deng, Ding Yuan +2
A sunspot is an ideal waveguide for a variety of magnetohydrodynamic waves, which carry a significant amount of energy to the upper atmosphere and could be used as a tool to probe…
A Compact Source for Quasi-Periodic Pulsation in an M-class Solar Flare
Ding Yuan, Song Feng, Dong Li +2
Quasi-periodic pulsations (QPP) are usually found in the light curves of solar and stellar flares, they carry the features of time characteristics and plasma emission of the flarin…
Spatial Distributions of Sunspot Oscillation Modes at Different Temperatures
Zhengkai Wang, Song Feng, Linhua Deng +1
Three- and five-minute oscillations of sunspots have different spatial distributions in the solar atmospheric layers. The spatial distributions are crucial to reveal the physical o…
A Subpixel Registration Algorithm for Low PSNR Images
Song Feng, Linhua Deng, Guofeng Shu +3
This paper presents a fast algorithm for obtaining high-accuracy subpixel translation of low PSNR images. Instead of locating the maximum point on the upsampled images or fitting t…
High-frequency Oscillations in the Atmosphere above a Sunspot Umbra
Feng Wang, Hui Deng, Bo Li +6
We use high spatial and temporal resolution observations, simultaneously obtained with the New Vacuum Solar Telescope and Atmospheric Imaging Assembly (AIA) on board the Solar Dyna…
Midterm Periodicity Analysis of the Mount Wilson Magnetic Indices Using the Synchrosqueezing Transform
Song Feng, Lan Yu, Feng Wang +2
A novel time--frequency technique, called the synchrosqueezing transform (SST), is used to investigate the midterm periodic variations of magnetic fields on the solar surface. The…
An imaging study of a complex solar coronal radio eruption
S. W. Feng, Y. Chen, H. Q. Song +2
Solar coronal radio bursts are enhanced radio emission excited by energetic electrons accelerated during solar eruptions, studies on which are important for investigating the origi…
On the relationship between G-band bright point dynamics and their magnetic field strengths
Yunfei Yang, Qiang Li, Kaifan Ji +4
G-band bright points (GBPs) are regarded as good manifestations of magnetic flux concentrations. We aim to investigate the relationship between the dynamic properties of GBPs and t…
Diagnostics on the source properties of type II radio burst with spectral bumps
S. W. Feng, Y. Chen, X. L. Kong +4
In recent studies (Feng et al., 2012; Kong et al., 2012), we proposed that source properties of type II radio bursts can be inferred through a causal relationship between the speci…
Radio signatures of CME-streamer interaction and source diagnostics of type II radio burst
S. W. Feng, Y. Chen, X. L. Kong +4
It has been suggested that type II radio bursts are due to energetic electrons accelerated at coronal shocks. Radio observations, however, have poor or no spatial resolutions to pi…
Streamer Wave Events Observed in Solar Cycle 23
S. W. Feng, Y. Chen, B. Li +4
In this paper we conduct a data survey searching for well-defined streamer wave events observed by the Large Angle and Spectrometric Coronagraph (LASCO) on-board the Solar and Heli…
Multi-waveband polarimetric observations of NRAO 530 on parsec-scale
Y. J. Chen, Z. -Q. Shen, S. -W. Feng
We report on multi-bands VLBA polarimetric observations of NRAO 530 in February 1997. Total intensity, EVPA distributions at all these frequencies are presented. Model fitting has…
Multi-Frequency VLBI Observations of NRAO 530
S. -W. Feng, Z. -Q. Shen, H. -B. Cai +3
We report on VLBA observations of a gamma-ray bright blazar NRAO 530 at multiple frequencies (5, 8, 15, 22, 39, 43, and 45 GHz) in 1997 and 1999. These multi-epoch multi-frequency…
