arxiv.org/abs/2601.16674 Constraining Twin-Star Existence in Four-Parameter Maxwell Equation of State
A systematic study using a four-parameter Maxwell-CSS approach maps where twin stars could exist, requiring a strong hadron-to-quark phase transition. Under 2-sigma observational filters, twin stars reach at most 2.05 solar masses, with a discontinuity up to 7.76 times saturation density.
