The Milky Way Galaxy is the galaxy that our solar system belongs to.
A part of it is sean as the Milky Way in the night sky.
The Milky Way consists of hundreds of billion of stars and many nebulae.
We investigate their physical properties of these objects and the interactions between them.
What is Star Forming Regions?Stars form owning to gravitational collapse of interstellar medium. On the processes, proto-stars generate jets, and sometimes they emit strong radio/X ray radiation.
Orion nebula and Taurus Molecular Cloud are two famous star forming retions. There are many other star forming regions. Some of them show similar properties, while some others show different nature. We observe these regions using different techniques in order to understand the processes of star formation
What is a Variable Star?Red giants are the stars of end state that solar-type stars becomes to at the end of their lives. It is known that these stars becomes variables whose brightness peroiodically changes in cycles over ten days or more. These evolved stars are categolized based on pulsation periods/patterns.
These stars are losing their masses with significant amounts, and often times they show strong masers (microwave amplification by stimulated emission of radiation).
