Exoplanets around Stars of Different Masses and Evolutionary Stages

Sabine Reffert , LSW, Univ. Heidelberg (D)
ith about 4000 extrasolar planets orbiting about 3000 different host stars known today, we are now clearly in the realm of detailed statistical studies of planet and host star properties. Furthermore, rarer systems are found, which sometimes can constrain planet formation and evolution theories single-handedly. Here I will review the main results of two Doppler surveys: the Lick G and K giant survey, focusing on evolved and relatively massive host stars, as well as the Carmenes survey which targets M dwarfs, the least massive host stars. I will discuss both, ensemble properties as well as individual systems, and will summarize what we have learned so far.
