The Great Dimming of the Hypergiant Star RW Cephei: CHARA Array Images and Spectral Analysis

The cool hypergiant star RW Cephei is currently in a deep photometric minimum that began several years ago. This event bears a strong similarity to the Great Dimming of the red supergiant Betelgeuse that occurred in 2019–2020. We present the first resolved images of RW Cephei that we obtained with t...
