Stellar pulsations in evolved massive stars
Stellar pulsations are found in many different types of stars. Usually, the
regions in the Hertzsprung-Russell diagram (HRD) that are populated by pulsating
stars are connected with instability strips or domains. A star within such a
domain is particularly sensitive to small perturbations of its equilibrium
Recently, a new group of pulsating stars settled. These are the blue supergiants
(BSGs), i.e., massive stars that have evolved from O and B-type main sequence
In addition, indications for possible pulsations in a B[e] star have been found.
Both groups of stars are therefore worth being studied in more detail.
