TOI-1259Ab: A warm Jupiter orbiting a K-dwarf white-dwarf binary on a low-obliquity orbit

The evolution of one member of a stellar binary into a white dwarf has been proposed as a mechanism that triggers the formation of close-in gas giant planets. The star’s asymmetric mass loss during the Asymptotic Giant Branch stage gives it a velocity recoil or “kick” that can initiate eccentric Lid...
