HD 103774 and Its Planet
HD 103774 is a star 184 light-years away with a spectral type of F5 V, a main-sequence dwarf. Its reported mass estimate is 1.34 solar masses, larger than the Sun's, and its reported temperature is 6490 K, hotter than the Sun's. The star's age is 1.05 billion years. One planet is known to orbit this host.
That planet, HD 103774 b, was discovered in 2013 using the radial velocity method and has a minimum mass of 116 Earth masses, larger than Earth's, on an orbital period of 5.89 days. A minimum mass is a lower bound on the planet's true mass, so the actual figure could be higher.
