Kepler-429 Explained

Kepler-429 (KIC 10001893) is a variable subdwarf B star in the constellation Lyra, about 5,900 light years away.

The brightness of Kepler-429 changes unpredictably by up to 0.13 magnitudes. It has been classified as a V361 Hydrae variable, but also as a V1093 Herculis variable, which typically has slower variations and a cooler temperature. Over 100 pulsation modes were identified with periods from 256 seconds to over three hours.[1]

Planetary system

Kepler-429 has been reported to have three possible exoplanets,[2] though their existence is questioned. They were detected by orbital brightness modulation.[3]
