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…
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…
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…
Investigation of intergranular bright points from the New Vacuum Solar Telescope
Kai-Fan Ji, Jian-ping Xiong, Yong-yuan Xiang +4
Six high-resolution TiO-band image sequences from the New Vacuum Solar Telescope (NVST) are used to investigate the properties of intergranular bright points (igBPs). We detect the…
Dispersal of G-band bright points at different longitudinal magnetic field strengths
Yang Yunfei, Ji Kaifai, Feng Song +3
G-band bright points (GBPs) are thought to be the foot-points of magnetic flux tubes. The aim of this paper is to investigate the relation between the diffusion regimes of GBPs and…
Investigation of Umbral Dots with the New Vacuum Solar Telescope
Kaifan Ji, Xia Jiang, Song Feng +3
Umbral dots (UDs) are small isolated brightenings observed in sunspot umbrae. They are convective phenomena existing inside umbrae. UDs are usually divided into central UDs (CUDs)…
Characterising motion types of G-band bright points in the quiet Sun
Yun-Fei Yang, Hui-Xue Qu, Kai-Fan Ji +4
We study the motions of G band bright points (GBPs) in the quiet Sun to obtain the characteristics of different motion types. A high resolution image sequence taken with the Hinode…
