Qc is the ratio of the field curvature radius to the stellar radius with the value inversely proportional to the size of the star. Qc is typically assumed to be 10 for WDs but is larger in reality. The vertical line denotes the period of ASKAP J1935 + 2148. Even in the most conservative case of Qc = 10, we are able to rule out a white dwarf origin scenario. More details in Methods.
