  • ULAS J133553.45+113005.2 (also called ULAS1335) is a T-type brown dwarf in the constellation of Virgo. It was discovered in data from the UK Infrared Telescope (UKIRT) Infrared Deep Sky Survey (UKIDSS) Large Area Survey (LAS). Its discovery was reported June 2008. After identification, ULAS1335 was imaged using the UFTI camera on the UKIRT, on Mauna Kea, Hawaii, to confirm its photometric properties and location. It was spectroscopically confirmed as a T9 dwarf using the Gemini North telescope, also at Mauna Kea, and was imaged using IRAC on the Spitzer Space Telescope. The IRAC imaging confirmed it as the reddest (in near-to-mid-infrared colors) T dwarf yet discovered, and by inference the coolest. ULAS1334 was initially estimated to have a temperature around 550–600 K, a distance of 8–12 parsecs (26–39 light-years), and a mass of 15–31 Jupiter masses. More recent spectroscopic observations, using IRS on the Spitzer Space Telescope, give an effective temperature of 500–550 K. Since these temperature estimates are based on model comparisons, they should be treated with caution until the parallax of this object has been measured. (en)
  • ULAS J133553.45+113005.2는 표면 온도가 아주 낮은 갈색 왜성이다. 2008년 6월에 발견하였으며 표면온도는 약 550-600 K, 거리는 26-40 광년이다. 이 항성의 질량은 15-31 MJ이다. ULAS1335는 UKIRT 적외선 천체 측량 천문 관측소와 UKIDSS 거대 영역 측량 천문 관측소(LAS)가 최초로 발견한 갈색 왜성이다. 하와이의 마우나케아 산 천문대에서 관측하였다. 스피처 우주 망원경과 으로 측정한 결과, 분광형이 T9 ~ Y0으로 확인되었다. 분광형이 Y형인 경우의 별은 거의 없다고 봐도 과언이 아니다. 표면 온도는 금성의 737K(464도씨)보다 낮다.
