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…
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…
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…
