| dbo:abstract | Beta Indi, Latinized from β Indi, is the second brightest star in the southern constellation of Indus. It is visible to the naked eye as a faint, orange-hued point of light with an apparent visual magnitude of 3.67. The star is located approximately 600 light years from the Sun, based on parallax, but is drifting closer with a radial velocity of −5 km/s. The stellar classification of this star is K1II, matching an evolved bright giant. Earlier it had been categorized as an ordinary giant with a class of K0III. It is a hybrid giant with both a hot stellar corona and cool stellar winds, and is a weak X-ray source with a flux measured at (11±1)×10−14 ergs cm−1 s−1. Having consumed the supply of hydrogen at its core, this star has expanded off the main sequence and now has about 56 times the girth of the Sun. It is 53 million years old with 6.7 times the mass of the Sun. The star is radiating 1,183 times the Sun's luminosity from its enlarged photosphere at an effective temperature of 4,541 K. β Indi has a visual companion, CCDM J20548-5827B, with an apparent visual magnitude of approximately 12.5. As of 2015, it lies at an angular separation of 17.2″ along a position angle of 100° from the brighter component.

Considerando sua distância de 603 anos-luz em relação à Terra, sua magnitude absoluta é igual a −2.66. Pertence à classe espectral K0III. (pt) Beta Indi (β Indi, förkortat Beta Ind, β Ind) som är stjärnans Bayerbeteckning, är en ensam stjärna belägen i den västra delen av stjärnbilden Indianen. Den har en skenbar magnitud på 3,66 och är synlig för blotta ögat där ljusföroreningar ej förekommer. Baserat på parallaxmätning inom Hipparcosuppdraget på ca 5,4 mas, beräknas den befinna sig på ett avstånd på ca 600 ljusår (ca 180 parsek) från solen. (sv) 印第安座β，又名CP-58 7788，HD 198700、SAO 246784、HR 7986，是印第安座的一颗恒星，视星等为3.65，位于銀經338.16，銀緯-38.85，其B1900.0坐标为赤經20h 46m 59.8s，赤緯-58° -38.85′ 53″。该星质量接近7个太阳质量，是一个橙色的亮巨星。总辐射波段亮度达到太阳的2000倍，表面温度约为4450K，呈现出类似大角星的橙黄色。该星已经进入红巨星阶段，直径估计超过75倍太阳直径，并将进一步膨胀。该星年龄预计只有5000万年，由于质量较大，因此迅速演化。 (zh) |
