LEARNING OUTCOMES: Exoplanet research is one of the most rapidly developing subjects in astronomy. Many groups world-wide are actively involved in a broad range of observational and theoretical efforts. This course ties together these many avenues of investigation from the perspectives of observation, technology and theory to give a comprehensive, up-to-date review of the field.

KNOWLEDGE AND UNDERSTANDING: On completion of the course, the student will have acquired the knowledge of the demographics of the exoplanets, their physical characteristics and the observational methods to find and characterize them.

APPLYING KNOWLEDGE AND UNDERSTANDING: A written comprehensive report will be required on a single exoplanetary system and will be discussed with the class through an oral contribution.

MAKING JUDGEMENTS: At the end of the course, the student will be able to independently undertake one of the many lines of research in exoplanetary science.
