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

HD 111031 (50 G. Corvi) is a double star in the southern constellation of Corvus. With an apparent visual magnitude of 6.87, it is considered too faint to be readily visible to the naked eye. The distance to this star is 102 light years, but it is drifting closer to the Sun with a radial velocity of −20 km/s. It has an absolute magnitude of 4.42. The star has a relatively large proper motion, traversing the celestial sphere at an angular rate of 0.289 arcsec yr−1.

  • HD 111031 (50 G. Corvi) is a double star in the southern constellation of Corvus. With an apparent visual magnitude of 6.87, it is considered too faint to be readily visible to the naked eye. The distance to this star is 102 light years, but it is drifting closer to the Sun with a radial velocity of −20 km/s. It has an absolute magnitude of 4.42. The star has a relatively large proper motion, traversing the celestial sphere at an angular rate of 0.289 arcsec yr−1. This object is a solar analog with a stellar classification of G5 V; a G-type main-sequence star like the Sun that is generating energy through core hydrogen fusion. It is around five billion years old and is chromospherically inactive, with a projected rotational velocity of 1.7 km/s. The star has 1.13 times the mass and 1.27 times the radius of the Sun. It is radiating 1.5 times the Sun's luminosity from its photosphere at an effective temperature of 5,836 K. In 2020, a stellar companion was identified using high-contrast imaging. The study authors deem this most likely a K-type main-sequence star with a class of K5V, an angular separation of 1″ along a position angle (PA) of 300° corresponding to a projected separation of 30 AU, and around 11–15% of the mass of the Sun. An independent study published in 2021 identified a companion through speckle imaging. They propose this is a faint red dwarf with a class of M6 or later and a visual magnitude difference of 7.9 or more compared to the primary. It is located at a separation of 1.06″ along a PA of 121°, as of 2021. In 2022, the presence of a brown dwarf companion to this star was confirmed. It has a mass of 54.167+5.319−6.149 MJ, and orbits at a distance of 13.101+0.750−1.092 AU with a period of 46.740+3.194−4.870 years. (en)
  • HD 111031​ es una estrella de magnitud aparente +6,87.Está encuadrada en la constelación de Corvus, el cuervo, visualmente 2º50' al suroeste de ψ Virginis y 1º45' al noreste de VV Corvi.Se encuentra a 101 años luz del Sistema Solar.En 2007 se anunció el descubrimiento de un planeta alrededor de esta estrella.​ HD 111031 es una enana amarilla de tipo espectral G5V​ con una temperatura superficial de 5801 K.​Su luminosidad supera a la del Sol aproximadamente en un 38%​ y también su diámetro es algo más grande que el diámetro solar, en torno a un 17%.​Su velocidad de rotación proyectada —límite inferior de la misma— es de 1,9 km/s,​ siendo su período de rotación de 33,0 días.​Con una masa un 12% mayor que la del Sol, parece no haber consenso en cuanto a su edad; diversos estudios señalan cifras comprendidas entre los 3800 y los 6700 millones de años.​​​ HD 111031 presenta un índice de metalicidad más alto que al solar ([Fe/H] = +0,27).​Todos los distintos elementos evaluados son más abundantes que en nuestra estrella, destacando el sodio, cuya abundancia relativa es 2,5 veces más elevada que en el Sol ([Na/H] = +0,39).​Sin embargo, su contenido de litio es inferior al solar (logє[Li] < 0,75).​ (es)

  • HD 111031 är en ensam stjärna belägen i den norra delen av stjärnbilden Korpen. Den har en skenbar magnitud av ca 6,87 och kräver åtminstone en handkikare för att kunna observeras. Baserat på parallaxmätning inom Hipparcosuppdraget på ca 32,4 mas, beräknas den befinna sig på ett avstånd på ca 100 ljusår (ca 31 parsek) från solen. Den rör sig närmare solen med en heliocentrisk radialhastighet på ca -20 km/s. (sv)
