}}{{Starbox end}}LQ Andromedae (shortened as LQ And, also known as HR 9070 in the Bright Star Catalogue) is a variable star in the constellation Andromeda. Its maximum apparent visual magnitude is 6.5, placing it at the limit of the visibility to the naked eye. The brightness, however, drops down to 6.66 with a periodic cycle of roughly 7.44 hours.The stellar classification of this star is B4Ven,[ so it's a main sequence star that shows emission lines and broadened absorption lines induced by the fast projected rotational velocity of 300 km/s (the angle between the rotation axis and our line of sight has been estimated with a value of 72°).[12] This leads to the classification of the star as a Be star. Further proof is the compatibility between the rotational and luminosity variability periods.[17]] LQ Andromedae is also a spectroscopic binary with an orbital period of 7.413 days. Nothing much can be known of the secondary component, but it's likely a low-mass companion (M<0.5 {{solar mass}}). A circumstellar disk is also present in the system.[17] References1. ^1 2 3 4 5 {{cite DR2|1926411961766632960}}
