Active region upflows in various coronal structures and their coupling to the lower atmosphere
Yingjie Zhu, Louise Harra, Krzysztof Barczynski +13
Plasma upflows with a Doppler shift exceeding -10 km/s at active region (AR) boundaries are considered potential sources of the nascent slow solar wind. We investigate the driving…
Anomalous cross-field motions of solar coronal loops
Sudip Mandal, Hardi Peter, James A. Klimchuk +1
Here, we present several examples of unusual evolutionary patterns in solar coronal loops that resemble cross-field drift motions. These loops were simultaneously observed from two…
Stereoscopic observations reveal coherent morphology and evolution of solar coronal loops
B. Ram, L. P. Chitta, S. Mandal +2
Coronal loops generally trace magnetic lines of force in the upper solar atmosphere. Understanding the loop morphology and its temporal evolution has implications for coronal heati…
Small-scale Dynamo in Cool Stars III. Changes in the photospheres of F3V to M0V stars
Tanayveer S. Bhatia, Robert H. Cameron, Hardi Peter +1
Some of the quiet solar magnetic flux could be attributed to a small-scale dynamo (SSD) operating in the convection zone. An SSD operating in cool main-sequence stars is expected t…
Impulsive coronal heating during the interaction of surface magnetic fields in the lower solar atmosphere
L. P. Chitta, H. Peter, E. R. Priest +1
Coronal plasma in the cores of solar active regions is impulsively heated to more than 5 MK. The nature and location of the magnetic energy source responsible for such impulsive he…
Plasmoid-mediated reconnection in solar UV bursts
H. Peter, Y. -M. Huang, L. P. Chitta +1
UV bursts are transients in the solar atmosphere with an increased impulsive emission in the extreme UV lasting for one to several tens of minutes. They often show spectral profile…
