Hα Doppler Brightening and Lyman-α Doppler Dimming in Moving Hα Prominences
Charles L. Hyder,Bruce W. Lites +1 more
TL;DR: In this article, the effect that coherent motion has on the observed brightness of moving clouds above the photosphere was investigated and it was shown that steady state clouds (constant Ne and Te) that are moving perpendicular to the line of sight will appear brighter in Hα for speeds between 8 and 100 km/sec and dimmer for speeds greater than 135 km/ sec.
Journal ArticleDOI
Prominence Formation Associated with an Emerging Helical Flux Rope
Takenori J. Okamoto,Saku Tsuneta,Bruce W. Lites,Masahito Kubo,Takaaki Yokoyama,Thomas E. Berger,Kiyoshi Ichimoto,Yukio Katsukawa,Shin'ichi Nagata,Kazunari Shibata,Toshifumi Shimizu,Richard A. Shine,Yoshinori Suematsu,Theodore D. Tarbell,Alan M. Title +14 more
TL;DR: In this paper, the authors examined continuous observations of a prominence in NOAA AR 10953 with the Solar Optical Telescope on the Hinode satellite and found a signature suggesting that a helical flux rope emerges from below the photosphere under a pre-existing prominence.
Journal ArticleDOI
Localized sources of propagating acoustic waves in the solar photosphere
TL;DR: A time series of Doppler measurements of the solar photosphere with moderate spatial resolution is described in this article, which covers a portion of solar disk surrounding a small sunspot group.
Journal ArticleDOI
Dynamics of the Solar Chromosphere. II. Ca II H2V and K2V Grains versus Internetwork Fields
TL;DR: In this paper, the Advanced Stokes Polarimeter at the NSO/Sacramento Peak Vacuum Tower Telescope was used to search for spatio-temporal correlations between enhanced magnetic fields in the quiet solar internetwork photosphere and the occurrence of Ca II H2V grains in the overlying chromosphere.
Journal ArticleDOI
Observations and nonlinear force-free field modeling of active region 10953
Yingna Su,Yingna Su,Adriaan van Ballegooijen,Bruce W. Lites,Edward E. DeLuca,Leon Golub,P. C. Grigis,Guangli Huang,Haisheng Ji +8 more
TL;DR: In this article, a series of nonlinear force-free field (NLFFF) models are constructed using the flux-rope insertion method, and the axial flux of the flux rope in the best-fit models is ( 7 +/- 2) x 10(20) Mx.
