Dense, Warm Jupiter-sized Exoplanet Discovered

Astronomers have discovered a new exoplanet, TOI-4127 b, using NASA's TESS. The planet is a warm Jupiter-sized exoplanet orbiting a dwarf star and is more than two times as massive as Jupiter. The planet has a highly eccentric orbit and an equilibrium temperature of about 605.1 K. The researchers concluded that the planet may be a "hot Jupiter" progenitor, but only if a perturbing companion is present.
