SZ Lyncis is a
light years based on parallax measurements,[2] and it is drifting further away with a radial velocity of 34 km/s.[5]
The variability of this system was announced in 1949 by C. Hoffmeister.[12] V. Zessewitch generated a
Comparison of the times of maximum light by
spectroscopic binary with an orbital period of 3.14 years.[15] Radial velocity measurements by C. Bardin and M. Imbert in 1984 confirmed the binary nature of this system.[16] Updated orbital elements were published by T. J. Moffett and associates in 1988.[6]
This is a spectroscopic binary system with an
shell burning.[8] The secondary is likely a main sequence star with a class in the range F2 V – K3 V.[6]
