TOI-762 and TIC 46432937: LCs data
Listed in IVOA Registry (Virtual Observatory)
We present the discovery of TOI 762 A b and TIC 46432937 b, two giant planets transiting M-dwarf stars.
Description
Transits of both systems were first detected from observations by the NASA TESS mission, and the transiting objects are confirmed as planets through high-precision radial velocity observations carried out with Very Large Telescope/ESPRESSO. TOI 762 A b is a warm sub-Saturn with a mass of 0.251+/-0.042M_J_, a radius of 0.740+/-0.017R_J_, and an orbital period of 3.4717days.
It transits a mid-M-dwarf star with a mass of 0.442+/-0.025M_{sun}_ and a radius of 0.4250+/-0.0091 R_{sun}_. The star TOI 762 A has a resolved binary star companion, TOI 762 B, that is separated from TOI 762 A by 3.2" (~319AU) and has an estimated mass of 0.227+/-0.010M_{sun}_. The planet TIC 46432937 b is a warm super-Jupiter with a mass of 3.20+/-0.11M_J_ and radius of 1.188+/-0.030R_J_.

The planet's orbital period is P=1.4404days, and it undergoes grazing transits of its early M-dwarf host star, which has a mass of 0.563+/-0.029M_{sun}_ and a radius of 0.5299+/-0.0091R_{sun}_. TIC 46432937 b is one of the highest-mass planets found to date transiting an M-dwarf star. TIC 46432937 b is also a promising target for atmospheric observations, having the highest transmission spectroscopy metric or emission spectroscopy metric value of any known warm super-Jupiter (mass greater than 3.0M_J_, equilibrium temperature below 1000K).
