Two warm sub-Neptunes discovered transiting nearby K-type star HD 15906

7. 6. 2023 (accepted)

Two warm sub-Neptunes discovered transiting nearby K-type star HD 15906

Star system: HD 15906 | Distance from the Sun: 149 light years

The HD 15906 system is one of only six multi-planet systems with two warm (< 700 K) sub-Neptune sized planets transiting a bright star (G < 10 mag). It is an excellent target for detailed characterisation studies to constrain the composition of sub-Neptune planets and test theories of planet formation and evolution.
