Asteroseismology of low-mass He-core white dwarf stars (original) (raw)

Abstract

Recently, low-mass white dwarf stars (< 0.5 M ) have been detected in open and globular clusters. Though photometric variability has not been discovered in these objects yet, they are considered as potential pulsators. A powerful tool to study the internal structure and evolutionary properties of low-mass white dwarfs is Asteroseismology. Motivated by the possible detection of luminosity variations in the coming years, we present the first adiabatic and non adiabatic pulsational study applied to low-mass white dwarf stars in order to providing a theoretical basis to interpret the future observations.
