Discovery and Characterization of an Eccentric, Warm Saturn Transiting the Solar Analog TOI-4994

We present the detection and characterization of TOI-4994b (TIC 277128619b), a warm Saturn-sized planet discovered by the NASA Transiting Exoplanet Survey Satellite. TOI-4994b transits a G-type star ( V = 12.6 mag) with a mass, radius, and effective temperature of ${M}_{\star }=1.00{5}_{-0.061}^{+0....
