TOI-3984 A b and TOI-5293 A b: two temperate gas giants transiting mid-M dwarfs in wide binary systems

We confirm the planetary nature of two gas giants discovered by TESS to transit M dwarfs with stellar companions at wide separations. TOI-3984 A (J=11.93) is an M4 dwarf hosting a short-period (4.353326 \pm 0.000005 days) gas giant (M_p=0.14\pm0.03~\mathrm{M_{J}} and R_p=0.71\pm0.02~\mathrm{R_{J}}) with a wide separation white dwarf companion. TOI-5293 A... Show more
