It is a binary star with a low mass secondary star orbiting at a separation of around 250 times the radius of the Sun. The primary varies with both short term and long term periodicity.[14] References1. ^{{cite journal|bibcode=1999MSS...C05....0H|title=Michigan catalogue of two-dimensional spectral types for the HD Stars|journal=Michigan Spectral Survey|volume=05|pages=0|author1=Houk|first1=N.|last2=Swift|first2=C.|date=1999}} [2][3][4][5][6]2. ^1 {{citation | last1=Slettebak | first1=A. | title=Spectral types and rotational velocities of the brighter Be stars and A-F type shell stars | journal=Astrophysical Journal Supplement Series | volume=50 | pages=55–83 | date=September 1982 | doi=10.1086/190820 | bibcode=1982ApJS...50...55S }} 3. ^1 2 3 {{citation | last1=Haupt | first1=H.
