DMPP-4 b: A Close-Orbiting Planet Around a Hotter, Larger Star
DMPP-4 is a single-star system 82.6 light-years away. Its star has a spectral type of F5-F8 V, with an age of 2.15 billion years, a mass of 1.25 solar masses, a radius of 1.38 solar radii, and a temperature of 6400 K. Each of these measured properties places the star above the Sun: it is more massive, larger, and hotter.
One planet is known around DMPP-4. DMPP-4 b was found in 2023 using the radial velocity method, which measures the wobble a planet's gravity induces in its star's motion; repeated wobbles reveal the planet and its orbital period. The planet has a minimum mass of 12.2 Earth masses, larger than Earth's, and an orbital period of 3.5 days. That minimum mass is a lower bound on the planet's true mass, not an exact value.
