Researchers from the Yunnan Observatories of the Chinese Academy of Sciences (CAS) have conducted a detailed asteroseismic analysis on an extremely low-mass white dwarf (WD) that exhibits suspected pressure mode (p-mode) pulsations. They not only detect the abundance profiles inside the WD, but also provide theoretical support for the reality of the p-modes.
