Extended Data Fig. 8: MESA evolutionary models of ZTF J1813+4251.
From: A dense 0.1-solar-mass star in a 51-minute-orbital-period eclipsing binary

MESA binary evolution models (Extended Data Table 1). Red, black and blue lines show models that overflow their Roche lobes after 94, 95 and 97 percent of the donor’s main-sequence lifetime. The dashed vertical line shows 51 minutes.
