The KMT-2020-BLG-0414L System: A White Dwarf with Two Microlensing Planets
KMT-2020-BLG-0414L is a white dwarf host star located 3980 light-years away. Its mass is 0.49 solar masses, which is smaller than the Sun's mass.
Two planets orbit this host star, both discovered in 2021 using the microlensing method. KMT-2020-BLG-0414L b has a mass 1.87 Earth masses, making it the smallest among the listed planets. No orbital period is reported for this planet. KMT-2020-BLG-0414L c has a mass 8580 Earth masses, making it the largest among the listed planets, and no orbital period is reported for it either.
The reported mass estimates for both planets are larger than Earth's. The mass of KMT-2020-BLG-0414L c is roughly 27 times Jupiter's mass.
