Composition & Properties

• Types of interstellar dust (silicates, carbonaceous materials, etc.).
• Physical properties (size, charge, temperature).

Introduction

Interstellar dust is a fundamental component of the universe, playing a crucial role in the formation of stars, planets, and galaxies. Composed primarily of small, solid particles like silicates, carbon, and ice, interstellar dust grains vary in size, typically ranging from a few nanometers to a micrometer. These particles are formed in the outer layers of dying stars and are dispersed into the interstellar medium. Their properties, such as shape, size distribution, and composition, significantly influence their interaction with light and gas, affecting the physical and chemical processes in space, including the formation of protoplanetary disks.
