TOI-1442 b and TOI-2445 b: two potentially rocky ultra-short period planets around M dwarfs

Context. Exoplanets with orbital periods of less than one day are known as ultra-short period (USP) planets. They are relatively rare products of planetary formation and evolution processes, but especially favourable for characterisation…
