CoRoT-7 is an active star, whose orbiting planets and their masses have been under debate since their initial detection. In the previous studies, CoRoT-7 was found to have two planets, CoRoT-7b and CoRoT-7c with orbital periods of 0.85 and 3.69 days,

Measured spectral shifts due to intrinsic stellar variability (e.g., pulsations, granulation) and activity (e.g., spots, plages) are the largest source of error for extreme precision radial velocity (EPRV) exoplanet detection. Several methods are des

After the detection of exoplanets using TESS, a major hurdle in the mass characterisation of these bodies with follow-up radial velocity(RV) observations is the contamination due to spurious stellar activity signals, as it is challenging to different
