Star wr104
WebWR104 is rotating. Like more than 60% of the other 230 Wolf Rayet stars identified in our galaxy, WR104 is in a binary system, with a rotation period of about 240 days. A key property of these massive, hot stars is that the radiation pressure is so high, the outer shells of the star are constantly being blown off into the local solar wind. WebThis curious star, known as Wolf-Rayet 104, lies in the constellation of Sagittarius. Because it is so far from us, the apparent size of the spiral around the star is so small that its discovery relied on advanced imaging techniques that utilized the full resolving power of the Keck Telescope, the world's largest telescope.

A rare opportunity of observing a lunar occultation of a Wolf–Rayet star (WR104) in the near-infrared K band (2.2 µm) was utilized to probe the thick dust envelope surrounding the star at a high one-dimensional angular resolution (∼2 mas). Analysis of the occultation light curve shows a dust structure departing significantly from …
