Wind Roche-Lobe Overflow (WRLOF) is a mass-transfer mechanism proposed byMohamed and Podsiadlowski (2007) for stellar binaries wherein the windacceleration zone of the donor star exceeds its Roche lobe radius, allowingstellar wind material to be transferred to the accretor at enhanced rates.WRLOF may explain characteristics observed in blue lurkers and blue stragglers.While WRLOF has been implemented in rapid population synthesis codes, it hasyet to be explored thoroughly in detailed binary models such as MESA (a 1Dstellar evolution code), and over a wide range of initial binaryconfigurations. We incorporate WRLOF accretion in MESA to investigate widelow-mass binaries at solar metallicity. We perform a parameter study over theinitial orbital period and stellar mass. In most of the models where weconsider angular momentum transfer during accretion, the accretor is spun up tothe critical (or break-up) rotation rate. Then we assume the star develops aboosted wind to efficiently reduce the angular momentum so that it couldmaintain a sub-critical rotation. Balanced by boosted wind loss, the accretoronly gains $\sim 2\%$ of its total mass, but can maintain a near-criticalrotation rate during WRLOF. Notably, the mass-transfer efficiency issignificantly smaller than in previous studies in which the rotation of theaccretor is ignored. We compare our results to observational data of bluelurkers in M67 and find that the WRLOF mechanism can qualitatively explain theorigin of their rapid rotation, their location on the HR diagram and theirorbital periods.
