Coronal holes are the darkest and least active regions of the Sun, as observed both on the
solar disk and above the solar limb. Coronal holes are associated with rapidly expanding …

Coronal jets represent important manifestations of ubiquitous solar transients, which may be
the source of significant mass and energy input to the upper solar atmosphere and the solar …

THE solar corona (the outermost portion of the Sun's atmosphere) is far hotter than
the'surface'(the photosphere). Recent observations of X-ray jets1á€-4 (collimated flows of …

Context. Recent observations by the Extreme Ultraviolet Imager (EUI) on board Solar Orbiter
have characterized prevalent small-scale transient brightenings in the corona above the …

We performed two-dimensional numerical simulations of solar coronal X-ray jets by solving
the resistive magnetohydrodynamic (MHD) equations. The simulations were based on the …

We propose a model for the jetting activity that is commonly observed in the Sun's corona,
especially in the open-field regions of polar coronal holes. Magnetic reconnection is the …

The heating of the solar chromosphere and corona is a long-standing puzzle in solar
physics. Hinode observations show the ubiquitous presence of chromospheric anemone jets …

Since their discovery over 100 years ago, there have been many suggestions for the origin
and development of solar spicules. Because the velocities of spicules are comparable to the …

The solar X-ray observing satellite Yohkoh has discovered various new dynamic features in
solar flares and corona, eg, cusp-shaped flare loops, above-the-loop-top hard X-ray …

The twentieth century has witnessed the transformation of astronomy from celestial
mechanics to astrophysics. While optical telescopes may have presented a peek into the …
