HD 129445 is a G type star found in the Circinus constellation located approximately 220 light-years away from the Sun based on parallax. It is invisible to the naked eye with an apparent visual magnitude of 8.80. The star has been under the Magellan Planet Search Program observation due to its absolute visual magnitude and high metallicity. The Magellan program conducted 17 doppler velocity tests, which spans a full orbital period. The results led the program to detect a planet dubbed HD 129445 b whose readings was accurate to the Keplerian orbital model.

  • HD 129445 är en solliknande -stjärna som är belägen 213,74 ljusår från Jorden i Cirkelpassaren. Den har en skenbar magnitud på 8,80 och en absolut magnitud på 4,65. Den har 127 procent solens luminositet. År 2010 upptäcktes en gasjätte-exoplanet runt stjärnan . (sv)
  • HD 129445是一顆位於圓規座的黃矮星,距離地球約219光年。該恆星因為可見光絕對星等和金屬量與太陽類似,被列入觀測對象。該計畫對HD 129445進行17次徑向速度觀測以獲得完整軌道週期資料,因此發現了行星HD 129445 b。 (zh)
  • HD 129445 é uma estrela na constelação de Circinus. Com uma magnitude aparente visual de 8,79, é invisível a olho nu. Com base em medições de paralaxe, está localizada a aproximadamente 220 anos-luz (67,6 parsecs) da Terra. É uma estrela de classe G da sequência principal (anã amarela) com um tipo espectral de G6 V e temperatura efetiva de 5 646 K. É portanto muito parecida com o Sol, que possui tipo espectral de G2 V e temperatura efetiva de 5 778 K. HD 129445 possui uma massa equivalente a 109% da massa solar. Sua metalicidade, a abundância de elementos além de hidrogênio e hélio, é significativamente superior à solar, com uma abundância de ferro de 2,34 vezes o valor solar. (pt)
