K2-36: A K-Type Dwarf and Its Two Known Planets
K2-36 is a K-type main-sequence dwarf 358 light-years away. A spectral type of K2 V places it in the cooler, redder part of the K class, and its measured properties are 0.79 solar masses, 0.718 solar radii, a temperature of 4920 K, and an age of 1.4 billion years. Its mass and radius are each smaller than the Sun's, and its temperature is cooler. Two planets are known to orbit this host.
Both planets were found by the transit method, in which a planet passes in front of its star from our viewpoint and produces a small dip in observed brightness; repeated dips help establish orbital periods. K2-36 b, discovered in 2016, is an Earth-like planet with a radius of 1.43 Earth radii, a mass of 4.3 Earth masses, and an orbital period of 1.42 days. Its radius and mass are both larger than Earth's, and its mean density is 8.1 g/cm³, 1.47 times Earth's. Among the listed planets, K2-36 b has the shortest year and the smallest radius and mass.
K2-36 c, also discovered in 2016 by transit, is Neptune-like. It has a radius of 3.2 Earth radii, a mass of 7.9 Earth masses, and an orbital period of 5.34 days. Its radius and mass are larger than Earth's, and its mean density is 1.33 g/cm³, 0.241 times Earth's. Among the listed planets, K2-36 c has the longest year and the largest radius and mass.
