-
The surfaces of the white dwarfs merge together until the 1.4 SolMass Chandrashekhar limit is reached, where is WDs collapses and forms into the SNIa.

The reasoning behind the mass constraints is that the progenitor stars must be close enough so that when they convert into WDs the orbit can degrade enough so that they can merge together and form a SNIa.

Based on the numbers of soft resolved X-rays from such nuclear-burning WD sources, this set the "…upper limit on the luminosity of WDs can be obtained."

The number of SNIa is likely is this investigation from WD mergers, but is this because of a fundamental aspect of the ratio of WDs by accretion / mergers or something else.

You also oddly mention "magnesium WDs" I assume you mean Oxygen-Neon ONe white dwarfs which are the heaviest WDs possible.

I remember seeing some work on these WDs over the past decade.

While noting that their current data is insufficient to accurately determine the masses of these objects, the authors do posit that their progenitors may have descended from the most massive stars avoiding core collapse, in which case these WDs would be expected to be massive too.

The authors of the current paper state The only plausible explanation for the observed O/C abundances is that these two WDs have overall very low carbon mass fractions, and hence represent naked ONe cores.

From the paper, they say; "In this work, we revisit the scenario of promptly detonating carbon-oxygen CO WDs."

This might be the dumbest question ever - and maybe I should google it, maybe the wiki for the WDs - but how do you keep spinning for that long without getting dizzy and collapsing?
