On the Existence of Long-period Decayless Oscillations in Short Active Region Loops
The Astrophysical JournalDecayless kink oscillations, characterized by their lack of decay in amplitude, have been detected in coronal loops of varying scales in active regions, the quiet Sun, and coronal holes. Short-period (

Sources of magnetic fields in recurrent interplanetary streams [PDF]
The sources of magnetic fields in recurrent streams were examined. Most fields and plasmas at 1 AU were related to coronal holes, and the magnetic field lines were open in those holes.

The Astrophysical JournalCoronal holes are recognized as the primary sources of heliospheric open magnetic flux (OMF). However, a noticeable gap exists between in situ measured OMF and that derived from remote-sensing observations of the Sun.

Effect of coronal temperature on the scale of solar chromospheric jets
, 2015 We investigate the effect of coronal temperature on the formation process of solar chromospheric jets using two-dimensional magnetohydrodynamic simulations of the region from the upper convection zone to the lower corona.

What drives solar-EUV jets seen in equatorial coronal holes?
Results in Physics, 2016 Recent observations of jets in solar coronal holes that include multi-wavelength data such as EUV movies have shown that most of those jets are not driven in the way suggested by the standard model.

Soft X-ray telescope (SXRT) [PDF]
The soft X-ray telescope (SXRT) will provide direct images of the solar corona with spatial resolution of about 1 arcsecond. These images will show the global structure of the corona, the location and area of coronal holes, and the presence of even the ...

Hydrogen Lyman-alpha and Lyman-beta radiances and profiles in polar coronal holes
, 2009 The hydrogen Lyman-alpha plays a dominant role in the radiative energy transport in the lower transition region, and is important for the stud- ies of transition-region structure as well as solar wind origin. We investigate the Ly-alpha profiles obtained

The Astrophysical Journal, 2009 Here, we explore the nature of small-scale jet-like structures and their possible relation to explosive events and other known transient features, like spicules and macrospicules, using high-resolution spectroscopy obtained with the Solar and Heliospheric Observatory/Solar Ultraviolet Measurements of Emitted Radiation instrument.
