  3. Abstract:
  4. TRAPPIST-I is an ultra-cool dwarf that hosts seven known transiting planets. We present photometry of the system obtained using three telescopes at ESO La Silla (the Danish i-54-m telescope and the 2-2-m MPI telescope) and Paranal (Unit Telescope i of the Very Large Telescope). We obtained 18 light-curves from ±e Danish telescope, eight from the 2-2-m and four from the VLT. From these we measure 25 times of mid-transit for four of the planets (b, c, f, g). These light-curves and times of mid-transit will be useful in determining the masses and radii of the planets, which show variations in their transit times due to gravitational interactions. © 2022 Rutherford Appleton Laboratory.
