TOI-544: A Cool Dwarf with Two Known Planets
TOI-544 is a star 134 light-years away with two known planets. The host star is 9 billion years old, with a mass of 0.631 solar masses, a radius of 0.623 solar radii, and a temperature of 4170 K. Its mass, radius, and temperature are all smaller or cooler than the Sun's.
TOI-544 b is a Super-Earth discovered by transit in 2022. Its radius is 2.02 Earth radii, larger than Earth's, and its mass is 2.89 Earth masses, also larger than Earth's. It completes an orbit in 1.55 days, the shortest year among the listed planets.
TOI-544 c was discovered by radial velocity in 2023. Its minimum mass is 21.5 Earth masses, larger than Earth's, and its orbital period is 50.1 days, the longest year among the listed planets.
