WASP-15 is a magnitude 11 star located about 1000 light-years away in the constellation Centaurus. The star, which is more massive, larger, hotter, and more luminous than the Sun, is also less metal-rich than the Sun. WASP-15 has one known planet in its orbit, WASP-15b; the planet is a Hot Jupiter with an anomalously high radius, a phenomenon which may be explained by the presence of an internal heat source. The star was first observed by the SuperWASP program in 2006; future measurements in 2007 and 2008, as well as follow-up observations and analysis, eventually led to the discovery of WASP-15b using the transit method and Doppler spectroscopy.

  • WASP-15, également nommée Nyamien, est une étoile située à environ 284 pc (∼926 a.l.) de la Terre dans la constellation du Centaure. D'un âge estimé à environ 3,9 milliards d'années, l'étoile est plus massive, plus grande, plus chaude et plus lumineuse que le Soleil. À la fin des années 2000, on y découvre WASP-15b, une exoplanète de taille semblable à celle de Jupiter. (fr)

  • WASP-15는 바다뱀자리 방향으로 지구로부터 약 1000 광년 떨어져 있는 항성이다. 겉보기 등급은 약 11로 맨눈으로는 볼 수 없다. 이 별은 태양보다 더 무겁고, 크고, 뜨거우며 밝다. 그러나 대기중 중원소 함량은 태양보다 적다. WASP-15 주위를 도는 외계 행성 WASP-15b가 발견된바 있으며 이 행성은 비정상적으로 반지름이 큰 뜨거운 목성이다. 이처럼 덩치가 큰 이유로 내부 열원 때문에 가열되어 부풀어 올랐을 것으로 보고 있다. 이 별은 슈퍼WASP 프로그램의 일환으로 2006년 관측되었으며 이후 2007년과 2008년에 추가 연구 및 분석이 이루어졌다. 그 결과 통과법 및 도플러 분광법을 이용하여 외계 행성 WASP-15b를 발견하게 되었다.
