(Phys.org)—Astronomers have recently discovered non-radial oscillations in a hot, helium-atmosphere white dwarf designated PG 0112+104. The newly detected 11 independent pulsation modes in this white dwarf could be essential for researchers testing the radial differential rotation and internal compositional stratification of highly evolved stellar remnants. The findings were presented in a paper published Dec. 22 on the arXiv pre-print server.
