Abstract
The Atacama Large Millimeter/submillimeter Array (ALMA) is a new
powerful tool for observing the Sun at high spatial, temporal, and
spectral resolution. These capabilities can address a broad range of
fundamental scientific questions in solar physics. The radiation
observed by ALMA originates mostly from the chromosphere—a complex
and dynamic region between the photosphere and corona, which plays a
crucial role in the transport of energy and matter and, ultimately, the
heating of the outer layers of the solar atmosphere. Based on first
solar test observations, strategies for regular solar campaigns are
currently being developed. State-of-the-art numerical simulations of the
solar atmosphere and modeling of instrumental effects can help constrain
and optimize future observing modes for ALMA. Here we present a short
technical description of ALMA and an overview of past efforts and future
possibilities for solar observations at submillimeter and millimeter
wavelengths. In addition, selected numerical simulations and
observations at other wavelengths demonstrate ALMA's scientific
potential for studying the Sun for a large range of science cases.
