Magnetic Reconnection Invoked by Sweeping of the CME-Driven Fast-Mode Shock

Guiping Zhou, Guannan Gao, Jingxiu Wang +4

Coronal waves exist ubiquitously in the solar atmosphere. They are important not only in their own rich physics but also essential candidates of triggering magnetic eruptions in th…

Doppler shift oscillations of a sunspot detected by CYRA and IRIS

D. Li, X. Yang, X. Y. Bai +4

Context. The carbon monoxide (CO) molecular line at around 46655 A in solar infrared spectra is often used to investigate the dynamic behavior of the cold heart of the solar atmosp…

An investigation of flare emissions at multiple wavelengths

Dong Li, Alexander Warmuth, Lei Lu +1

We report multi-wavelength observations of four solar flares on 2014 July 07. We firstly select these flares according to the soft X-ray (SXR) and extreme ultraviolet (EUV) emissio…

Photometric and Spectroscopic Study of Flares on Ross 15

Jian-Ying Bai, Ali Esamdin, Xing Gao +2

We conducted photometric and spectroscopic observations for Ross 15 in order to further study the flare properties of this less observed flare star. A total of 28 B-band flares are…

Estimates of current helicity and tilt of solar active regions and Joy's law

K. Kuzanyan, N. Kleeorin, I. Rogachevskii +2

The tilt angle, current helicity and twist of solar magnetic fields can be observed in solar active regions. We carried out estimates of these parameters by two ways. Firstly, we c…

A White-light Flare Powered by Magnetic Reconnection in the Lower Solar Atmosphere

Yongliang Song, Hui Tian, Xiaoshuai Zhu +3

White-light flares (WLFs), first observed in 1859, refer to a type of solar flares showing an obvious enhancement of the visible continuum emission. This type of enhancement often…

Observations of a quasi-periodic pulsation in the coronal loop and microwave flux during a solar preflare phase

Dong Li, Ying Li, Lei Lu +3

We report a quasi-periodic pulsation (QPP) event simultaneously detected from the spatial displacements of coronal loop at both EUV images and microwave emission during the preflar…

Dynamics of descending knots in a solar prominence and their possible contributions to the heating of the local corona

Yi Bi, Bo Yang, Tng Li +2

The knots in solar prominences are often observed to fall with nearly constant velocity, but the associated physical mechanism is currently not well understood. In this letter, we…

Quasi-periodic pulsation detected in Lyman-alpha emission during solar flares

Dong Li, Lei Lu, Zongjun Ning +3

We investigated the quasi-periodic pulsation (QPP) in Lyman-alpha, X-ray and extreme-ultraviolet (EUV) emissions during two solar flares, i.e., an X-class (SOL2012-01-27T) and a C-…

Sympathetic eruptions of two filaments with an identifiable causal link observed by the Solar Dynamics Observatory

Zhiping Song, Yijun Hou, Jun Zhang +1

Filament eruptions occurring at different places within a relatively short time internal, but with a certain physical causal connection are usually known as sympathetic eruption. S…

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…

The origin and effect of hemispheric helicity imbalance in solar dynamo

S. Yang, V. V. Pipin, D. D. Sokoloff +2

In this paper we study the effects of hemispheric imbalance of magnetic helicity density on breaking the equatorial reflection symmetry of the dynamo generated large-scale magnetic…

Magnetic Gradient: A Natural Driver of Solar Eruptions

Baolin Tan, Yan Yan, Ting Li +2

It is well-known that there is a gradient, there will drive a flow inevitably. For example, a density-gradient may drive a diffusion flow, an electrical potential-gradient may driv…

The mean tilt of sunspot bipolar regions: theory, simulations and comparison with observations

N. Kleeorin, N. Safiullin, K. Kuzanyan +3

A theory of the mean tilt of sunspot bipolar regions (the angle between a line connecting the leading and following sunspots and the solar equator) is developed. A mechanism of for…
