TOI-1431: A Massive Star With a Close-Orbiting Jupiter-Like Planet

TOI-1431 is a single star 486 light-years away with a spectral type of Am C. The star is 0.29 billion years old and has a mass of 1.9 solar masses, a radius of 1.92 solar radii, and a temperature of 7690 K. Its reported mass, radius, and temperature are all larger or hotter than the Sun's. One planet orbits this host.

TOI-1431 b is a Jupiter-like planet discovered by transit in 2021. It completes an orbit every 2.65 days. Its radius is 16.7 Earth radii, larger than Earth's, and its mass is 992 Earth masses, also larger than Earth's. That mass is roughly 3.12 times Jupiter's mass. TOI-1431 b's mean density is 1.17 g/cm³, 0.213 times Earth's.
