Beta Virginis , a nameLatinised fromβ Virginis , is astar in theequatorial constellation ofVirgo . It has the proper nameZavijava (/ˌ z æ v ɪ ˈ dʒ æ v ə [ 11] [ 12] [ 13] beta ', is the fifth-brightest star in Virgo with anapparent visual magnitude of 3.604.[ 2] light-years based onparallax ;[ 1] radial velocity of +4.1 km/s.[ 6] ecliptic , so it can beocculted by theMoon and (rarely) byplanets . The next planetary occultation of Beta Virginis will take place on 9 November 2210, byVenus ;[ 14] South Pole .[ 15]
This is anF-type main-sequence star with astellar classification of F9 V,[ 5] core hydrogen fusion .Sun-like oscillations have been detected in Beta Virginis, allowing its internal structure to be modeled in more detail.[ 16] [ 6] [ 4] projected rotational velocity of 4.3 km/s[ 9] main sequence lifetime.[ 3] [ 4] metal-rich (that is, it has a higher preponderance of elements heavier thanhelium ).[ 8] [ 7] luminosity of the Sun from itsphotosphere at aneffective temperature ofK [ 7]
According to Nelson & Angel (1998),[ 17] jovian planets in wide orbits. The authors have set an upper limit of 1.9, 5 and 23Jupiter masses for the putative planets with orbital periods of 15, 25 and 50 years, respectively. Also Campbell et al. 1988[ 18] brown dwarfs around Beta Virginis. However, more recent studies have not confirmed the existence of anysubstellar companion around Beta Virginis yet.McDonald Observatory team has set limits to the presence of one or more planets[ 19] astronomical units .
β Virginis (Latinised toBeta Virginis ) is the star'sBayer designation .
It bore the traditional namesZavijava (alsoZavijah ,Zavyava andZawijah ) andAlaraph .[ 20] Zavijava is from theArabic زاوية العواء zāwiyat al-c awwa’ 'corner of the barking (dog)'. In 2016, theInternational Astronomical Union organized aWorking Group on Star Names (WGSN)[ 21] Zavijava for this star on 21 August 2016 and it is now so entered in the IAU Catalog of Star Names.[ 13]
