They use a variety of tools and techniques to study the Sun, including:
* Spacecraft: Telescopes and other instruments in space, such as the Solar Dynamics Observatory (SDO) and the Parker Solar Probe, allow scientists to observe the Sun from close up.
* Ground-based telescopes: Telescopes on Earth, such as the Daniel K. Inouye Solar Telescope, can also be used to study the Sun.
* Computer models: Scientists use computer models to simulate the Sun's activity and to understand the processes that occur within it.
Solar physicists study a wide range of topics related to the Sun, including:
* The Sun's internal structure and composition
* The Sun's magnetic field
* Solar flares and coronal mass ejections
* The Sun's influence on Earth's atmosphere and climate
So, while there isn't one specific scientist who solely studies the Sun, solar physicists are the experts in this field!
