| Abstract: |
Stellar companions separated by < 100 au can reduce the number of observed planets, but what are
the effects on temperate, Earth-like worlds? We outline scenarios in which stellar companions could either
suppress or enhance the occurrence of small, cool planets. We find that binary star samples sizes > 50 are
needed to meaningfully test suppression and enhancement scenarios. To obtain a sample of this size requires
pushing HWO’s technical limits for sensitivity and starlight suppression.
This article is an adaptation of a science case document developed as part of HWO’s Demographics
and Architectures Steering Committee. |
