Ju n 20 06 A hot transient jet from η Carinae

η Carinae (η Car) is a stellar binary system with a period of 5.54 years. It harbors one of the brightest and most massive stars in our galaxy. This paper presents spectroscopic evidence for a fast (up to 2,000 km s) X-ray jet of ionized gas launched from η Car just before what is believed to be the binary periastron (point of smallest binary separation… CONTINUE READING
