The HD 93963 A transiting system: A 1.04 d super-Earth and a 3.65 d sub-Neptune discovered by TESS and CHEOPS
We present the discovery of two small planets transiting HD 93963A (TOI-1797), a GOV star (M * = 1.109 ± 0.043M ⊙, R * = 1.043 ± 0.009 R ⊙) in a visual binary system. We combined TESS and CHEOPS space-borne photometry with MuSCAT 2 ground-based photometry, `Alopeke and PHARO high-resolution imaging, TRES and FIES reconnaissance spectroscopy, and
