These objects’ surface-confined g-modes were numerically computed by Don Winget in a paper that confirmed the elemental stratification of these objects’ envelopes. ZZ Cetis are a class of these objects of D·A·V type. Classical estimates imply that the mass of these objects is inversely proportional to their volume. Accretion onto these objects produces (*) cataclysmic variables, which can result in carbon (10[1])detonation. These objects name an O·D·E describing their electron degeneracy (10[1])pressure that can be solved to obtain an upper bound on the size of these objects of one point four solar masses, the Chandrasekhar limit. For 10 points, name these low-mass stellar remnants, the ultimate fate of red giant stars. ■END■
