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

Epsilon Delphini (ε Delphini, abbreviated Eps Del, ε Del), officially named Aldulfin /ælˈdʌlfən/, is a solitary, blue-white hued star in the northern constellation of Delphinus. It is visible to the naked eye with an apparent visual magnitude of 4.03. Based upon an annual parallax shift of 9.87 mas as seen from the Earth, the system is located about 330 light-years from the Sun. At Epsilon Delphini's distance, the visual magnitude is diminished by an extinction factor of 0.11 due to interstellar dust. The star is moving closer to the Sun with a radial velocity of −19 km/s.

This is a B-type giant star with a stellar classification of B6 III. It has 4.6 times the Sun's radius and is radiating 676 times the solar luminosity from its photosphere at an effective temperature of 13,614 K. The star may be slightly variable, occasionally brightening to magnitude 3.95. It is spinning with a projected rotational velocity of 52 km/s. (en)

  • Aldulfin eller Epsilon Delphini (ε Delphini, förkortat Epsilon Del, ε Del) är en ensam stjärna belägen i den mellersta delen av stjärnbilden Delfinen. Den har en skenbar magnitud på 4,03, är synlig för blotta ögat där ljusföroreningar ej förekommer. Baserat på parallaxmätning inom Hipparcosuppdraget på ca 9,9 mas, beräknas den befinna sig på ett avstånd på ca 330 ljusår (ca 101 parsek) från solen. På det beräknade avståndet minskar stjärnans skenbara magnitud med 0,11 enheter genom skymning orsakad av interstellärt stoft. Stjärnan flyttar sig närmare solen med en radiell hastighet av ca 19 km/s. (sv)
