Kepler-411 is a binary star system. Its primary star Kepler-411A is a K-type main-sequence star, orbited by the red dwarf star Kepler-411B on a wide orbit, discovered in 2012. [6]

Contents

Primary star

The primary star's surface temperature is 4,773  K . Kepler-411A is similar to the Sun in its concentration of heavy elements, with a metallicity Fe/H index of 0.11±0.1, [7] but is much younger at an age of 212±31 million years. [9]

Kepler-411A exhibits significant starspot activity, with starspots covering 1.7+0.3
−0.2% of the stellar surface. [12] Darker starspots are concentrated around the equator of the star. Kepler-411A exhibits differential rotation, but with smaller amount of differential shear compared to the Sun. [8]

The companion Kepler-411B is 533  au away from Kepler-411A. [10] It is a red dwarf and a flare star. [13]

Planetary system

In 2013, one planet, named Kepler-411b, was discovered, [14] followed by planet Kepler-411c in 2016. Third planet in system detected by transit method, d, along with e detected by radial velocity method, were discovered in 2019. [15] [9]
