Atmospheric Mass Loss from TOI-1259 A b, a Gas Giant Planet with a White Dwarf Companion

Atmospheric Mass Loss from TOI-1259 A b, a Gas Giant Planet with a White Dwarf Companion

The lack of close-in Neptune-mass exoplanets evident in transit surveys has largely been attributed to either photoevaporative mass loss or high-eccentricity migration. To distinguish between these two possibilities, we investigate the origins of TOI-1259 A b, a Saturn-mass (0.4 M _J , 1.0 R _J ) ex...
