Star in the constellation of Columba
WZ Columbae , also known asHD 38170 , is a solitary,[ 19] star located in the southernconstellation Columba , the dove. It has anapparent magnitude of 5.28,[ 3] naked eye . Based onparallax measurements from theGaia spacecraft , the object is about 365light years distant.[ 2] Solar System , having a heliocentricradial velocity ofkm/s [ 9]
The star was discovered to be avariable star when theHipparcos variable star designation in 1999.[ 20] slowly pulsating B-type star by theGeneral Catalogue of Variable Stars . However, observations from Hempel & Howlger (2003) reveal it to be overabundant instrontium andbarium .[ 14] Alpha2 Canum Venaticorum variable .[ 8] Hipparcos passband , it fluctuates betweenmagnitudes 5.27 and 5.29 over 1.38days .[ 7] [ 21] TESS data suggests a period of± 0.00004[ 16]
Thestellar classification of WZ Columbae is B9/9.5 V[ 5] main-sequence star with the characteristics of a B9 and B9.5 star. It has 3.07[ 4] mass of the Sun and is estimated to be 394million years old,[ 16] main sequence lifetime.[ 4] radius of 3.47 R ☉ [ 11] effective temperature ofK [ 4] luminosity 124 times that of theSun [ 12] photosphere . Like mostchemically peculiar stars , WZ Columbae has a relatively slowprojected rotational velocity atkm/s [ 15]
