| contents | I present a discovery of SB1 in the LAMOST MRS spectra of eclipsing contact binary V 0885 Per. Spectroscopic orbit has period only $P=21.8$ day, which will make it shortest known outer period in compact hierarchical triple system, if this SB1 is indeed bound to the inner system. Unfortunately quality of available spectra don't allow to give definitive answer to this question, although other explanation like a chance alignment seems to be unlikely. |
