Hard X-Ray Emission from Partially Occulted Solar Flares: RHESSI Observations in Two Solar Cycles
Frederic Effenberger, Fatima Rubio da Costa, Mitsuo Oka +5
Flares close to the solar limb, where the footpoints are occulted, can reveal the spectrum and structure of the coronal loop-top source in X-rays. We aim at studying the properties…
First Detection of Chromospheric Magnetic Field Changes During an X1-Flare
Lucia Kleint
Stepwise changes of the photospheric magnetic field, which often becomes more horizontal, have been observed during many flares. Previous interpretations include coronal loops that…
An Integrated System at the Bleien Observatory for Mapping the Galaxy
Chihway Chang, Christian Monstein, Joel Akeret +5
We describe the design and performance of the hardware system at the Bleien Observatory. The system is designed to deliver a map of the Galaxy for studying the foreground contamina…
Multi-wavelength Study of Transition Region Penumbral Subarcsecond Bright Dots Using IRIS and NST
Na Deng, Vasyl Yurchyshyn, Hui Tian +4
Using high-resolution transition region (TR) observations taken by the Interface Region Imaging Spectrograph (IRIS) mission, Tian et al. (2014b) revealed numerous short-lived subar…
Fine-pitch CdTe detector for hard X-ray imaging and spectroscopy of the Sun with the FOXSI rocket experiment
S. Ishikawa, M. Katsuragawa, S. Watanabe +8
We have developed a fine-pitch hard X-ray (HXR) detector using a cadmium telluride (CdTe) semiconductor for imaging and spectroscopy for the second launch of the Focusing Optics So…
The First Focused Hard X-ray Images of the Sun with NuSTAR
Brian W. Grefenstette, Lindsay Glesener, Säm Krucker +20
We present results from the the first campaign of dedicated solar observations undertaken by the \textit{Nuclear Spectroscopic Telescope ARray} ({\em NuSTAR}) hard X-ray telescope.…
Simulation of Quiet-Sun Hard X-rays Related to Solar Wind Superhalo Electrons
Wen Wang, Linghua Wang, Sam Krucker +1
In this paper, we propose that the accelerated electrons in the quiet Sun could collide with the solar atmosphere to emit Hard X-rays (HXRs) via non-thermal bremsstrahlung, while s…
The injection of ten electron/He-rich SEP events
Linghua Wang, Säm Krucker, Glenn M. Mason +2
We have derived the particle injections at the Sun for ten good electron/He-rich solar energetic particle (SEP) events, using a 1.2 AU particle path length (suggested by anal…
WISH VI. Constraints on UV and X-ray irradiation from a survey of hydrides in low- to high-mass YSOs
A. O. Benz, S. Bruderer, E. F. van Dishoeck +18
Hydrides are simple compounds containing one or a few hydrogen atoms bonded to a heavier atom. They are fundamental precursor molecules in cosmic chemistry and many hydride ions ha…
The first X-ray imaging spectroscopy of quiescent solar active regions with NuSTAR
I. G. Hannah, B. W. Grefenstette, D. M. Smith +15
We present the first observations of quiescent active regions (ARs) using NuSTAR, a focusing hard X-ray telescope capable of studying faint solar emission from high temperature and…
Data-driven Radiative Hydrodynamic Modeling of the 2014 March 29 X1.0 Solar Flare
Fatima Rubio da Costa, Lucia Kleint, Vahé Petrosian +2
Spectroscopic observations of solar flares provide critical diagnostics of the physical conditions in the flaring atmosphere. Some key features in observed spectra have not yet bee…
Ultra-narrow Negative Flare Front Observed in Helium-10830~Å using the 1.6 m New Solar Telescope
Yan Xu, Wenda Cao, Mingde Ding +10
Solar flares are sudden flashes of brightness on the Sun and are often associated with coronal mass ejections and solar energetic particles which have adverse effects in the near E…
