Addendum: Maximum Mass Ratio of AM CVn-Type Binary Systems and Maximum White Dwarf Mass in Ultra-Compact X-Ray Binaries, Published in Serb. Astron. J. No. 183 (2011), 63-69
Abstract
We recalculated the maximum white dwarf mass in ultra-compact X-ray binaries obtained in an earlier paper (Arbutina 2011), by taking the effects of super-Eddington accretion rate on the stability of mass transfer into account. It is found that, although the value formally remains the same (under the assumed approximations), for white dwarf masses M_2 ≳ 0.1 M_{{Ch}} mass ratios are extremely low, implying that the result for M_{max} is likely to have little if any practical relevance.
