The orbital evolution of planets orbiting ageing stars KU Leuven
Some 95% of all stars in the galaxy have an initial mass lower than 8 solar masses; it is now thought that the majority has at least one planetary companion. During the post-main-sequence evolution, these stars go through giant phases characterized by significant mass loss, large stellar radii, strong pulsations, and extreme luminosities. These changes in stellar characteristics may completely transform a planetary system: the stellar wind, ...
