| Abstract: |
Recent years have witnessed the discovery of many low-mass (≲ 0.45 M☉) white dwarf (WD) stars — expected to harbor He cores— in the field of the Milky Way and in several galactic globular and open clusters. Recently, three pulsating objects of this kind have been discovered: SDSS J184037.78+642312.3, J111215.82+111745.0, and J151826.68+065813.2. Motivated by these very exciting findings, and in view of the valuable asteroseismological potential of these objects, we present here the main outcomes of a detailed theoretical study on the seismic properties of low-mass He-core WDs based on fully evolutionary models representative of them. This study is aimed at providing a theoretical basis from which to interpret present and future observations of variable low-mass WDs. |
