2023RNAAS...7...75S - Research Notes of the AAS, 7, 75 (2023/April-0)
A Speckle Search for the Outer Companion of KIC 9832227.
SALINAS R. and HOWELL S.B.
Abstract (from CDS):
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.
