A speckle search for the outer companion of KIC 9832227
arXiv:2304.13729 · doi:10.3847/2515-5172/accc8b
Abstract
We present Gemini-N/'Alopeke speckle observations of KIC 9832227, a system originally predicted to become a red nova. The diffraction limited observations do not find an outer companion between 11 and 678 AU that could be responsible for the period changes of the system.
