About: RV Corvi

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

RV Corvi is an eclipsing binary star system in the southern constellation of Corvus. The brightness of the pair regularly ranges in apparent visual magnitude from 8.6 down to 9.16 over a period 18 hours, even the brightest of which is too faint to be visible to the naked eye. The system is located at a distance of approximately 690 light-years from the Sun based on parallax measurements, and is drifting further away with a radial velocity of ~19 km/s.

  • RV Corvi (en abrégé RV Crv) est une étoile binaire de la constellation du Corbeau, distante d'environ ∼690 a.l. (∼212 pc) de la Terre. Il s'agit d'une binaire à éclipses de type Beta Lyrae dont la magnitude apparente varie de 8,6 à 9,16 sur une période de 18 heures. Le système est composé d'une étoile de type F0 et d'une étoile de type G0 ; elles complètent une orbite l'une autour de l'autre en 0,747 jour (fr)
  • RV Corvi is an eclipsing binary star system in the southern constellation of Corvus. The brightness of the pair regularly ranges in apparent visual magnitude from 8.6 down to 9.16 over a period 18 hours, even the brightest of which is too faint to be visible to the naked eye. The system is located at a distance of approximately 690 light-years from the Sun based on parallax measurements, and is drifting further away with a radial velocity of ~19 km/s. The variability of this system was discovered by H. H. Swope. In 1942, Irene G. Buttery published an orbital period of 0.74728 days for the system, showing this is an eclipsing binary. It is a near-contact binary with both stars showing the effect of tidal interactions and the facing sides are less than 10% of the orbital separation apart, but are not in contact. One or both stars may show an excess of luminosity on their facing sides. The system is composed of stars of spectral types F0 and G0, which orbit each other every 0.7473 days. (en)
  • RV Ворона (лат. RV Corvi, HD 109796) — тройная звезда в созвездии Ворона на расстоянии приблизительно 689 световых лет (около 211 парсек) от Солнца. Видимая звёздная величина звезды — от +9,16m до +8,6m. Возраст звезды определён как около 1,465 млрд лет. Переменность открыта Генриеттой Своп**. Пара первого и второго компонентов — двойная затменная переменная звезда типа Беты Лиры (EB). Орбитальный период — около 0,7473 суток (17,934 часа). (ru)
