and Rotanev for components of Alpha and Beta Delphini, two stars which appeared in the Palermo star catalogue of 1814. They were eventually identified as the reversed spelling of Nicolaus Venator, a Latinised version of Nicolò Cacciatore, assistant to the astronomer Giuseppe Piazzi. It is not clear whether Piazzi intended to name the stars after his assistant, or if Cacciatore made the names up himself. In 2019, the IAU held a second NameExoWorlds campaign to celebrate the 100th anniversary of the IAU's founding. Azerbaijan named the star HD 152581 (16h 53m 44s / +11° 58′ 25″, in Ophiuchus) as Mahsati (Mahsati). Cuba named the star BD−17 63 as Felixvarela (Félix Varela). India named the star HD 86081 as Bibha (Bibha Chowdhuri). Spain named the star HD 149143 as Rosalíadecastro (Rosalía de Castro). Names not approved by the IAU Apart from the few formally approved by the IAU, and leaving aside commercial attempts, stars named after individuals fall broadly into two groups. The first group are those named openly for an individual connected with them in some way. The second, somewhat more obscurely, are those named after an individual but without explicitly making this clear. Openly named stars There is a growing number of stars whose common names honour individuals. Many of these were highly significant in some way when discovered, usually through having some unusual characteristic. The best source to get these names is Sky Catalogue 2000.0, Volume 2 (Double Stars, Variable Stars, and Nonstellar Objects), in the chapter Glossary Of Selected Astronomical Names. Abt's Star is SV Crateris (ADS 8115/ HD 98088/ β 600) in Crater. Named after Helmut Abt. Andrews' Star is a suspected variable star in Auriga (HD 37519 / SAO 58319 / HR 1938). Named after A. David Andrews. Anthelm's Nova/Star is Nova 1670 Vulpeculae, observed by Anthelme Voituret (aka père Anthelme / don Anthelme). Argelander's Star is Groombridge 1830, a high proper motion star. Named for Friedrich Wilhelm Argelander, who discovered its high proper motion in 1842. Argelander's second star is Lalande 21185, a nearby red dwarf star. Named also for Argelander, who discovered its high proper motion in 1857. Baade's Star is the pulsar in the Crab Nebula (Messier 1, Taurus). Also known as the Crab Pulsar, or PSR B0531+21. Named after Walter Baade. Babcock's Magnetic Star is HD 215441 in Lacerta. Named after Horace W. Babcock. Becklin's Star is IRC -10093 in Messier
