About: NGC 4349-127

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

NGC 4349-127 is a probable red giant approximately 6,100 light-years away in the constellation of Crux. As a member of the open cluster NGC 4349 (hence the name NGC 4349-127), it is located about 2000 parsecs (about 6500 light years) from the Sun. Its mass is estimated at 3.9 times Solar, and its age is about 200 million years. However, a 2018 study with the same C. Lovis as an author found that the radial velocity signal corresponding to the proposed substellar companion was most likely caused by stellar activity, and thus the companion does not exist.

dbo:abstract
  • NGC 4349-127 is a probable red giant approximately 6,100 light-years away in the constellation of Crux. As a member of the open cluster NGC 4349 (hence the name NGC 4349-127), it is located about 2000 parsecs (about 6500 light years) from the Sun. Its mass is estimated at 3.9 times Solar, and its age is about 200 million years. In 2007, this star was found to have a substellar companion. NGC 4349-127 b is a brown dwarf (based on its mass) with nearly 20 times the mass of Jupiter. Within an eccentricity of about 0.19, its orbit is moderately elliptical, about the same as Mercury in the Solar System. It orbits its host star at a distance of 2.38 AU in a period of 677.8 days. This object was discovered by Christophe Lovis and Michel Mayor of the Geneva Observatory using the radial velocity technique. However, a 2018 study with the same C. Lovis as an author found that the radial velocity signal corresponding to the proposed substellar companion was most likely caused by stellar activity, and thus the companion does not exist. (en)
  • NGC 4349-127 — красный гигант спектрального класса M III в созвездии Южного Креста на расстоянии примерно 6270 световых лет от Солнечной системы. Звезда относится к рассеянному звёздному скоплению NGC 4349, которое расположено примерно в 6500 световых годах (2000 пк) от Солнца. Масса звезды составляет порядка 4 солнечных массы, а возраст — 200 млн лет. В 2007 году на орбите звезды был обнаружен субзвёздный компаньон, вероятно, коричневый карлик. (ru)
