Insight into the Solar Plage Chromosphere with DKIST

The Astrophysical Journal
The strongly coupled hydrodynamic, magnetic, and radiation properties of the plasma in the solar chromosphere make it a region of the Sun's atmosphere that is poorly understood. We use data obtained with the high-resolution Visible Broadband Imager (VBI)

Alfvén Wave Heating of Solar Chromosphere Reexamined

The Astrophysical Journal
Models of heating the weakly ionized solar atmosphere by collisional damping of upward-propagating Alfvén waves, calculated under the assumption that only incompressible (intermediate-mode) MHD waves are involved, have predicted heating rates that do not

Source Region of the Solar Wind: Statistics of the Doppler Velocities at the Chromosphere

The Astrophysical Journal Letters
The solar wind has been extensively studied recently with in situ observations, and the understanding of its counterpart near the solar surface has also progressed significantly.

An In-depth Analysis of Quiet-Sun IRIS Brightenings

The Astrophysical Journal
Small-scale brightenings are ubiquitous, dynamic, and energetic phenomena found in the chromosphere. An advanced filter-detection algorithm applied to high-resolution observations from the Interface Region Imaging Spectrograph enables the detection of ...

IRIS2+: A Comprehensive Database of Stratified Thermodynamic Models in the Low Solar Atmosphere

The Astrophysical Journal Supplement Series
We present the most comprehensive collection of stratified-in-optical-depth thermodynamic models of the lower solar atmosphere. This database, named IRIS ^2+ , consists of 40,320 synthetic representative profiles (RPs) and their corresponding ...

The Effect of Plasma-β on the Heating Mechanisms during Magnetic Reconnection in Partially Ionized Low Solar Atmosphere

The Astrophysical Journal
We performed numerical simulations of magnetic reconnection with different strengths of magnetic fields from the solar photosphere to the upper chromosphere.

Differential Rotation of the Solar Chromosphere: A Century-long Perspective from Kodaikanal Solar Observatory Ca ii K Data

The Astrophysical Journal
Chromospheric differential rotation is a key component in comprehending the atmospheric coupling between the chromosphere and the photosphere at different phases of the solar cycle. In this study, we therefore utilize the newly calibrated multidecadal Ca
