About: 58 Leonis

An Entity of Type: star, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

58 Leonis is a possible binary star system in the southern part of the constellation of Leo, near the border with Sextans. It shines with an apparent magnitude of 4.85, making it bright enough to be seen with the naked eye. An annual parallax shift of 9.05±0.20 mas yields a distance estimate of 360 light years. It is moving further from the Sun with a heliocentric radial velocity of +6 km/s.

  • 58 Leonis is a possible binary star system in the southern part of the constellation of Leo, near the border with Sextans. It shines with an apparent magnitude of 4.85, making it bright enough to be seen with the naked eye. An annual parallax shift of 9.05±0.20 mas yields a distance estimate of 360 light years. It is moving further from the Sun with a heliocentric radial velocity of +6 km/s. This orange hued star is an evolved K-type giant with a stellar classification of K0.5 III Fe-0.5, indicating a mild underabundance of iron in its spectrum. It was identified as a barium star by P. M. Williams (1971). These are theorized to be stars that show an enrichment of s-process elements by mass transfer from a now-white dwarf companion when it passed through the asymptotic giant branch stage. MacConnell et al. (1972) classified 58 Leonis as a marginal barium star. De Castro et al. (2016) consider this to be only a probable barium star, because of the low degree of s-process enrichment, and they rejected it from their sample. Rather than having an evolved companion, it may instead have formed from a cloud that was mildly enriched with s-process elements. (en)
  • 58 Leonis, som är stjärnans Flamsteed-beteckning, är en möjlig dubbelstjärna, belägen i den södra delen av stjärnbilden Lejonet. Den har en skenbar magnitud av ca 4,85 och är svagt synlig för blotta ögat där ljusföroreningar ej förekommer. Baserat på parallaxmätning inom Hipparcosuppdraget på ca 9,1 mas, beräknas den befinna sig på ett avstånd på ca 360 ljusår (ca 110 parsek) från solen. Den rör sig bort från solen med en heliocentrisk radialhastighet på ca 6 km/s. (sv)
  • 58 Leonis (58 Leo, d Leo, d Leonis) é uma estrela na constelação de Leo. Com uma magnitude aparente de 4,82, é brilhante o suficiente para ser vista a olho nu. Medições de paralaxe mostram que está a aproximadamente 360 anos-luz (110 parsecs) da Terra. Sua magnitude absoluta visual é de -0,36. 58 Leonis é uma estrela de bário com uma classificação estelar de K1 III. A classe de luminosidade 'III' indica que é uma estrela gigante evoluída que já consumiu o hidrogênio em seu núcleo. Tem um raio 14 vezes maior que o raio do Sol e uma temperatura efetiva de 4 559 K. Com essa temperatura, tem a coloração alaranjada típica de estrelas de classe K. Assim como todas as estrelas de bário, tem uma estrela companheira anã branca. (pt)
