YBP 1194 (original) (raw)
YBP 1194 est une étoile naine jaune de l'amas ouvert M67, dans la constellation zodiacale du Cancer. De magnitude apparente 14,6 dans le spectre visible, elle n'est pas observable à l'œil nu. Comparable au Soleil par sa masse (1,01 ± 0,02 masse solaire) et son rayon (0,99 ± 0,02 rayon solaire), elle a une métallicité un peu plus élevée que celle du Soleil.

| dbo:abstract | YBP 1194 est une étoile naine jaune de l'amas ouvert M67, dans la constellation zodiacale du Cancer. De magnitude apparente 14,6 dans le spectre visible, elle n'est pas observable à l'œil nu. Comparable au Soleil par sa masse (1,01 ± 0,02 masse solaire) et son rayon (0,99 ± 0,02 rayon solaire), elle a une métallicité un peu plus élevée que celle du Soleil. (fr) YBP 1194 è una stella che fa parte dell'ammasso aperto M67, situato nella costellazione del Cancro, ad una distanza di 2772 anni luce dal sistema solare. Si tratta, assieme a HD 101364, della stella più simile al Sole conosciuta. Nel gennaio 2014 è stata annunciata la scoperta di un pianeta extrasolare in orbita attorno ad essa, avente un periodo di 6,9 giorni e una massa del 34% di quella di Giove. YBP 1194 fa parte di un piccolo gruppo dell'ammasso, chiamato M67-NGC 2682, che comprende oltre 500 stelle in un raggio di 10 anni luce. In confronto, il Sole ha 17 stelle ad una distanza di 10 anni luce e 134 a una distanza di 20 a.l. (it) YBP 1194는 게자리 방향의 M67 내 산개성단에 있는 G형 주계열성이다. 이 항성은 발견 당시 기준으로 표면 온도, 질량, 화학적 중원소 함유량 등등 태양과 가장 비슷한 '쌍둥이 태양'으로 볼 수 있다. (ko) YBP 1194 is a G-type main-sequence star, class G5V, in the open cluster M67 in the constellation Cancer. It is the best solar twin found to date, having the near exact temperature and mass as the Sun. YBP 1194 has a higher metallicity than the Sun and is 0.5 billion years younger at an age of 4.2 billion years old, but due to the distance, the error bar is high at ±1.6 billion years. On December 19, 2013, it was announced to have an extrasolar planet with a period of 6.9 days and a high eccentricity of 0.24 with a mass of 0.34 MJ. It is about 2,772 light-years (850 parsecs) from the Sun. It is packed in a small cluster, Messier 67, with a radius of 10 ly, with over 500 other stars. For comparison, the Sun has 17 stars at a distance of 10 ly and about 134 stars at a distance of 20 ly. (en) YBP1194 — звезда в созвездии Рака. Находится на расстоянии около 2700 световых лет от Солнца. Вокруг звезды обращается, как минимум, одна планета. Звезда принадлежит рассеянному скоплению M 67. (ru) |
