A Statistical Survey of Faint Solar X-ray Transients Observed by NuSTAR
Reed B. Masek, Lindsay Glesener, Jessie Duncan +14
In this paper, we use a highly sensitive telescope to characterize solar X-ray transients ranging from microflares in active regions down to weakly energetic brightenings in the qu…
First joint X-ray solar microflare observations with NuSTAR and Solar Orbiter/STIX
Natália Bajnoková, Iain G. Hannah, Kristopher Cooper +5
We present the first joint spectral and imaging analysis of hard X-ray (HXR) emission from 3 microflares observed by the Nuclear Spectroscopic Telescope ARray (NuSTAR) and Solar Or…
Thermal Evolution of an Active Region through Quiet and Flaring Phases as Observed by NuSTAR XRT, and AIA
Jessie Duncan, Reed B. Masek, Albert Y. Shih +6
Solar active regions contain a broad range of temperatures, with the thermal plasma distribution often observed to peak in the few millions of kelvin. Differential emission measure…
Sustaining high-solar-activity research
Albert Y. Shih, Amir Caspi, Jessie Duncan +3
Research efforts that require observations of high solar activity, such as multiwavelength studies of large solar flares and CMEs, must contend with the 11-year solar cycle to a de…
The need for focused, hard X-ray investigations of the Sun
Lindsay Glesener, Albert Y. Shih, Amir Caspi +46
Understanding the nature of energetic particles in the solar atmosphere is one of the most important outstanding problems in heliophysics. Flare-accelerated particles compose a hug…
On the faintest solar coronal hard X-rays observed with FOXSI
Juan Camilo Buitrago-Casas, Lindsay Glesener, Steven Christe +23
Solar nanoflares are small eruptive events releasing magnetic energy in the quiet corona. If nanoflares follow the same physics as their larger counterparts, they should emit hard…
NuSTAR observations of a repeatedly microflaring active region
Kristopher Cooper, Iain G. Hannah, Brian W. Grefenstette +6
We investigate the spatial, temporal, and spectral properties of 10 microflares from AR12721 on 2018 September 9 and 10 observed in X-rays using the Nuclear Spectroscopic Telescope…
NuSTAR Observation of Energy Release in Eleven Solar Microflares
Jessie Duncan, Lindsay Glesener, Brian W. Grefenstette +6
Solar flares are explosive releases of magnetic energy. Hard X-ray (HXR) flare emission originates from both hot (millions of Kelvin) plasma and nonthermal accelerated particles, g…
FOXSI-2 Solar Microflares II: Hard X-ray Imaging Spectroscopy and Flare Energetics
Juliana T. Vievering, Lindsay Glesener, P. S. Athiray +7
We study the nature of energy release and transfer for two sub-A class solar microflares observed during the second flight of the Focusing Optics X-ray Solar Imager (FOXSI-2) sound…
Accelerated electrons observed down to <7 keV in a NuSTAR solar microflare
Lindsay Glesener, S"am Krucker, Jessie Duncan +6
We report the detection of emission from a non-thermal electron distribution in a small solar microflare (GOES class A5.7) observed by the Nuclear Spectroscopic Telescope Array (Nu…
