Second exoplanet discovered orbiting binary star TOI 1338

Binary star TOI 1338 has at least two exoplanets orbiting it. Astronomers led by Matthew Standing discovered the second one using radial velocity method and data from observatories La Silla and VLT. Exoplanet TOI 1338 c is the first one detected solely by the radial velocity method and the system TOI 1338 is now the second known to have multiple exoplanets orbiting more than one star.
