About: HD 44594

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

HD 44594 is a star in the southern constellation Puppis. It has an apparent visual magnitude of 6.64, so it can be seen with the naked eye from the southern hemisphere under good viewing conditions. Based upon parallax measurements, it is located at a distance of about 82 light-years (25 parsecs) from the Earth, giving it an absolute magnitude of 4.56. This star has been examined in the infrared using the Spitzer Space Telescope. However, no excess emission was discovered, which might otherwise have indicated the presence of a circumstellar debris disk of orbiting dust.

  • HD 44594 is a star in the southern constellation Puppis. It has an apparent visual magnitude of 6.64, so it can be seen with the naked eye from the southern hemisphere under good viewing conditions. Based upon parallax measurements, it is located at a distance of about 82 light-years (25 parsecs) from the Earth, giving it an absolute magnitude of 4.56. Measurement of the star's spectrum show it to match a stellar classification of G1.5V, which is close to the Sun's spectral class of G2V. In the wavelength range 3200–8800 Â, the energy emission of this star is very similar to the Sun, and thus it is considered a solar analog. The luminosity class 'V' means this is a main sequence star that is generating energy through the thermonuclear fusion of hydrogen at its core. The effective temperature of the outer envelope of HD 44594 is 5,840 K, which is giving it the characteristic yellow hue of a G-type star. This star has about 108% of the Sun's mass and is about the same radius as the Sun. It may be slightly younger than the Sun with an estimated age of 4.1 billion years. the abundance of elements other than hydrogen or helium, what astronomers term the star's metallicity, is 41% higher than in the Sun. The projected rotational velocity of the star is 4.4 km s−1, which gives the minimum azimuthal velocity along the star's equator. This star has been examined in the infrared using the Spitzer Space Telescope. However, no excess emission was discovered, which might otherwise have indicated the presence of a circumstellar debris disk of orbiting dust. (en)
  • HD 44594 (HR 2290 / HIP 30104 / SAO 217861)​ es una estrella en la constelación de Puppis —la popa del Argo Navis— de magnitud aparente +6,59. Está situada en el extremo suroeste de la constelación, al noroeste de Canopo (α Puppis), noreste de β Pictoris y oeste de τ Puppis. HD 44594 es una enana amarilla de tipo espectral G1.5V con una temperatura superficial de 5840 K.​Es un posible gemelo solar,​ ya que posee unas características físicas muy parecidas a las de nuestra estrella.Tiene una masa un 8% mayor que la masa solar​ y, con un diámetro aproximadamente un 11% más grande que el del Sol,​ gira sobre sí misma con una velocidad de rotación proyectada de 2,7 km/s.Sin embargo, su luminosidad es un 25% mayor que la solar,​ mientras que su contenido en metales —entendiendo como tales aquellos elementos distintos al hidrógeno— es un 40% mayor que el del Sol.​Su edad varía, según la fuente consultada, entre los 4100​ y los 5500 millones de años.​ HD 44594 se encuentra a 83,8 años luz de distancia del Sistema Solar. Las estrellas conocidas más próximas a ella son los sistemas estelares y , ambos a menos de 8 años luz.​ (es)
  • HD 44594 är en ensam stjärna, belägen i den södra delen av stjärnbilden Akterskeppet. Den har en skenbar magnitud av ca 6,64 och kräver åtminstone en handkikare för att kunna observeras. Baserat på parallaxmätning inom Hipparcosuppdraget på ca 39,8 mas, beräknas den befinna sig på ett avstånd på ca 82 ljusår (ca 25 parsek) från solen. Den rör sig bort från solen med en heliocentrisk radialhastighet på ca 59 km/s. (sv)
