Thirty Years of Hunting for Extra-solar planets - A Personal View
In 1988 I joined the quest find exoplanets with the radial velocity method. At the time, exoplanet research was virtually unknown, and no extra-solar planets had been discovered. Since then, we have discovered several thousand extra-solar planets found mostly via the radial velocity and transit methods.
Planets with masses as low as the Earth and even in the habitable zone of low mass stars have been detected. We have also taken the first steps to characterize these new worlds in terms of their masses, radii, densities, internal structure and atmospheric composition. This was unforeseen thirty years ago. In my talk I will review the expectations we had when we first started searching for extra-solar planet, he surprises along the way, and what to expect in the future from extra-solar planet research.
