The Astrophysical JournalUnderstanding the mechanisms underlying the heating of the solar atmosphere is a fundamental problem in solar physics. The lower atmosphere of the Sun (i.e., photosphere and chromosphere) is composed of weakly ionized plasma.

Performance of a building integrated collector for solar heating and radiant cooling [PDF]
, 2011 Due to their limited temperature range, unglazed solar collectors have long been relegated to providing low cost heating in applications such as swimming pool heating systems.

The Astrophysical JournalWe report on a flare-driven coronal rain event observed along postflare loops during the decay phase of an X1.6-class solar flare. Although high-resolution studies of flare-driven coronal rain have been conducted, imaging spectroscopic studies are rare ...

Solar Spectroscopy and (Pseudo-)Diagnostics of the Solar Chromosphere
, 2010 I first review trends in current solar spectrometry and then concentrate on comparing various spectroscopic diagnostics of the solar chromosphere. Some are actually not at all chromospheric but just photospheric or clapotispheric and do not convey ...

FINANCIAL ANALYSIS OF SOLAR ENERGY APPLICATIONS WITH ENDOGENOUS SYSTEM SIZING [PDF]
This paper is concerned with analysis of economic feasibility of solar energy systems. Methodology for estimating energy output from different sized systems is briefly presented, and this is used to determine technical coefficients for a mixed integer ...

The Astrophysical JournalModels currently fail to reproduce observations of the coldest regions in the Sun’s atmosphere, though recent work suggests the thermal Farley–Buneman instability (TFBI) may play a critical role.

How Are the Abnormally Hot Chromosphere and Corona Heated by the Solar Magnetic Fields?
The Astrophysical JournalAbstract The corona is a structure possessed by stars, including the Sun. The abnormal heating of the solar corona and chromosphere is one of the greatest mysteries in modern astronomy. While state-of-the-art observations have identified some candidates of magnetic activity events that could be responsible for this abnormal heating, and ...

Chromospheric counterparts of solar transition region unresolved fine structure loops
, 2018 Low-lying loops have been discovered at the solar limb in transition region temperatures by the Interface Region Imaging Spectrograph (IRIS). They do not appear to reach coronal temperatures, and it has been suggested that they are the long-predicted ...
