Abstract

Among the many cosmic cataclysms that can influence life, we focus on the impact that the most critical phases of the late-stage stellar evolution may have on planets. To give an example, the red giant expansion of the Sun will probably engulf the inner planets, including perhaps the Earth. Although these studies are far from being able to predict anything concerning life, they are starting to make preliminary predictions about what can happen to planets within a few AU of the star. We present a short review of this field, in particular regarding the first detections of old evolved planets orbiting post-red giant branch stars.
