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…

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…
