Solar and Heliospheric Physics with the ngVLA
Abstract
The ngVLA offers unprecedented sensitivity, angular resolution, and frequency bandwidth for studies of astrophysical phenomena from millimeter to decimeter wavelengths, including the Sun and solar wind. This paper summarizes key solar and heliospheric science objectives that can be addressed by the ngVLA. For the Sun these include: 1) the quantitative measurement of coronal magnetic fields; 2) magnetic energy release; 3) particle acceration and transport; 4) drivers of space weather; and 5) the structure and dynamics of the solar chromosphere and corona. For the outer corona and the inner heliosphere the science objectives include 1) solar wind acceleration; 2) the development of solar wind turbulence; 3) transient disturbances (e.g., coronal mass ejections) in the solar wind. The techniques that will be exploited for these studies will be briefly reviewed and the necessary capabilities of the ngVLA in support of these techniques will be discussed.
