Sunrise III/SUSI reveals extended and spectrally structured Ca II K emission above the solar limb

Ivan Milić, Christopher M. J. Osborne, Francisco A. Iglesias +32

The Sunrise III/SUSI instrument performed a sit-and-stare observation of the off-limb emission in the Ca II K line core, with a combination of excellent temporal and spectral resol…

Diversity of morphology of type II spicules in MURaM-ChE simulations

Sanghita Chandra, Robert Cameron, Damien Przybylski +1

Spicules are ubiquitous, small-scale features in the solar atmosphere, exhibiting a jet-like appearance most clearly identified by their apparent motion in off-limb observations. W…

Statistical properties of spicules in MURaM-ChE

Sanghita Chandra, Robert Cameron, Damien Przybylski +1

Numerical simulations of the solar chromosphere have progressed towards reproducing spicules, which are transient features observed at the solar limb using spectral lines such as H…

Probing chromospheric fine structures with a Hα proxy using MURaM-ChE

Sanghita Chandra, Robert Cameron, Damien Przybylski +3

H observations of the solar chromosphere reveal dynamic small-scale structures known as spicules at the limb and rapid blue and red shifted excursions (RBEs/RREs) on-disk. We wa…

Recovery of the Solar Cycle from Maunder-like Grand Minima Episodes: A Quantification of the Necessary Polar Flux Threshold through Solar Dynamo Simulations

Chitradeep Saha, Sanghita Chandra, Dibyendu Nandy

The 11-yr cycle of sunspots undergo amplitude modulation over longer timescales. As a part of this long-term modulation in solar activity, the decennial rhythm occasionally breaks,…

Evidence of persistence of weak magnetic cycles driven by meridional plasma flows during solar grand minima phases

Chitradeep Saha, Sanghita Chandra, Dibyendu Nandy

Long-term sunspot observations and solar activity reconstructions reveal that the Sun occasionally slips into quiescent phases known as solar grand minima, the dynamics during whic…
