Abstract
The processes leading to star formation are one of main topics of research in astronomy. The area has developed rapidly during last decade, stimulated by the construction of large telescopes and the launch of space telescopes. There are still many unanswered questions concerning the early stages of star formation as well as the many detailed processes in the later stages. In addition, more than 150 exoplanets orbiting nearby solar-type stars have been found up to now, and therefore we should also investigate the processes involved in the formation of planetary systems around stars. At this moment of planning to build the Korean Large Telescopes, we have formed a research team to work together and contribute to the understanding of these fundamental questions. The research topics we are planning to study with the future Korean Large Telescopes are presented.
