Identified 9 new planet candidates orbiting M dwarfs.
Discovered 5 gas giants, a rare occurrence around M dwarfs.
Highlighted TIC 12999193.01 as a promising target for follow-up observations.
Abstract
We present the detection of 9 new planet candidates orbiting M dwarfs, identified using an independent search and vetting pipeline applied to TESS Full-Frame Image (FFI) data from Sectors 1 to 63. Our candidates include planets as small as 1.4 , with orbital periods up to 20 days. Among the 9 new candidates, we identified 5 gas giants, which represent a rare and unexpected outcome of planet formation. Our findings add to the growing sample of giant planets around M dwarfs found by TESS. We discuss their follow-up potential for mass measurements through radial velocity observations and atmospheric characterization through transmission spectroscopy. We highlight TIC 12999193.01 as a particularly unique gas giant candidate in an eccentric orbit and excellent potential for atmospheric characterisation.
