WASP-43b (original) (raw)
WASP-43 b est une exoplanète orbitant autour de l'étoile WASP-43, elle a été découverte en 2011 par la méthode des transits. Au moment de sa découverte, sa période orbitale d'environ 0,8 jour (19,2 heures) est la deuxième plus courte à avoir été découverte, après celle de WASP-19 b. De plus, toujours au moment de sa découverte, WASP-43 b était la Jupiter chaude avec l'orbite la plus près de son étoile, ce qui s'explique par la faible masse de son étoile.

(fr) WASP-43 b è un pianeta in transito in orbita attorno alla giovane stella attiva , una nana arancione che si trova nella costellazione del Sestante, distante 261 anni luce dal sistema solare. Il pianeta ha una massa due volte superiore a quella di Giove e un raggio approssimativamente uguale. WASP-43 b era già uno degli obiettivi del programma SuperWASP, prima di venire studiato con gli strumenti dell'osservatorio di La Silla in Cile, che ne confermarono l'esistenza, fornendo anche le caratteristiche fisiche e orbitali del pianeta. L'annuncio della scoperta è avvenuto nell'aprile 2011. Quando fu scoperto il pianeta aveva un periodo orbitale di circa 0,8 giorni (19,2 ore), il secondo più breve mai rilevato dopo quello di WASP-19 b, ed era il gioviano caldo noto più vicino alla propria stella, fatto che potrebbe essere spiegato dalla piccola massa della stella madre. (it) WASP-43bは地球から見てろくぶんぎ座の方向にある恒星、WASP-43を公転している太陽系外惑星である。2011年にスーパーWASPプロジェクトによって発見された。 (ja) WASP-43b is a transiting planet in orbit around the young, active, and low-mass star WASP-43 in the constellation Sextans. The planet is a hot Jupiter with a mass twice that of Jupiter, but with a roughly equal radius. WASP-43b was flagged as a candidate by the SuperWASP program, before they conducted follow-ups using instruments at La Silla Observatory in Chile, which confirmed its existence and provided orbital and physical characteristics. The planet's discovery was published on April 14, 2011. At the time of its discovery, WASP-43b had an orbital period of approximately 0.8 days (19.2 hours), the second-shortest orbit ever detected, surpassed only by WASP-19b. In addition, at the time of discovery, WASP-43b was the most closely orbiting hot Jupiter known, a phenomenon that can most likely be explained by its host star's low mass. In August 2022, this planet and its host star were included among 20 systems to be named by the third NameExoWorlds project.

(ru) WASP-43b是一個環繞年輕且高活動力的恆星的凌日行星，位於六分儀座。WASP-43b質量幾乎是木星的兩倍，屬於熱木星，但是半徑稍小於木星。WASP-43b是被超廣角尋找行星計畫的電腦程式選為候選者，之後經由智利拉西拉天文台的儀器分析確認了它的存在，並確定了它的軌道和物理性質。該行星的發現是在2011年4月14日出版的論文中得到證實。 WASP-43b的軌道週期在發現時確定是0.8日（19.2小時），是已確認太陽系外行星中公轉週期第二短的（只比WASP-19b長）。此外，WASP-43b是已知的熱木星中距離母恆星最近的，這現象也許可以母恆星的低質量解釋。 (zh) |
