Planet Rotation Limits Habitability

Life can't exist on a planet that rotates too fast or slow. This is another Goldilocks problem for astrobiologists to consider.

Much as astrobiologists would like to see the birth of a new planet, the ones we observe seem to be dying, not being born.
Observations Upset Models of Stellar Evolution
December 22, 2011
Stellar evolution models go back decades. Ever since the Hertzsprung-Russell diagram came out in 1910 (graphing temperature against luminosity), showing most stars fell on a line called the “main sequence”, astrophysicists have sought to understand the life cycle of stars from birth to death. In general, the story goes, collapsing clouds of gas and dust produce main-sequence stars that burn nuclear fuel till they run out. Depending on their masses, they end up as supernovae, red giants or slowly-cooling cinders. While red dwarfs cool down slowly into the darkness, supernovae and red giants eject mass outward into space . Two new planets found close to a red giant are among new headaches for theorists.
