Subdwarf B star
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.
[3] 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.
[7]
Planetary system
Kepler-429 has been reported to have three possible
exoplanets ,
[8] though their existence is questioned.
[9] They were detected by
orbital brightness modulation .
