KESPRINT view of small transiting planets and the discovery of TOI-2290b

The TESS mission made a major leap forward in exoplanet science, in which small transiting exoplanets around bright host stars can be characterised in detail. With precise planetary mass and radius measurements, we can infer their bulk densities and compositions and explore trends in exoplanet distributions. KESPRINT is an international collaboration of scientists who use ground-based facilities to follow-up on small transiting exoplanet detections from space missions. In this talk, an overview of KESPRINT discoveries will be presented, highlighting the discovery of an ultrashort-period (P=0.38d) super-Earth planet TOI-2290b (Rp = 1.29 +/- 0.08 Rearth and Mp = 2.75 +/- 0.52 Mearth) transiting a M dwarf star.
