Denis Vida points our attention at a recently published meteor related paper:

Meteors – light from comets and asteroids

Abstract: In studies of the oldest solar system bodies – comets and asteroids – it is their fragments – meteoroids – that provide the most accessible planetary material for detailed laboratory analysis in the form of dust particles or meteorites. Some asteroids and comets were visited by spacecrafts and returned interplanetary samples to Earth, while missions Hayabusa 2 and OSIRIX-REx visiting asteroids Ryugu and Bennu are ongoing. However, the lack of representative samples of comets and asteroids opens the space to gain more knowledge from direct observations of meteoroids. At collision with the Earth’s atmosphere, meteoroids produce light phenomena known as meteors. Different methods can be used to observe meteors, allowing us to study small interplanetary fragments, which would otherwise remain undetected. Numerous impressive meteor showers, storms and meteorite impacts have occurred throughout the recorded history and can now be predicted and analyzed in much more detail. By understanding the dynamics, composition and physical properties of meteoroids, we are able to study the formation history and dynamical evolution of the solar system. This work presents an introduction to meteor astronomy, its fundamental processes and examples of current research topics.
