Field of the southern B[e] star HD 87643

Image: ESO/F. Millour et al.

This image, showing a very rich field of stars towards the Carina arm of the Milky Way, is centred on the star HD 87643, a member of the class of B[e] stars. The amazing image is set ablaze by a flurry of stars of all colours and brightnesses, some of which are seen against a backdrop of clouds of dust and gas. The red emission nebula is RCW47 and was catalogued in 1960. HD 87643 has been extensively studied with a full range of ESO telescopes, including the Very Large Telescope Interferometer (VLTI). Surrounded by a complex, extended nebula that is the result of previous violent ejections, the star is shown to have a companion. Interactions in this double system, surrounded by a dusty disc, may be the engine fuelling the star’s remarkable nebula. The image, taken with the Wide Field Imager on the MPG/ESO 2.2-metre telescope at La Silla, is based on data obtained through different filters: B, V and R. The field of view is around 30 x 30 arcminutes.

More fascinating particle physics from CERN as well: the story of “neutral currents“, which paved the way to the discovery of the W and Z boson intermediaries of the electroweak force.

  1. Pretty nice post. I just stumbled upon your weblog and wanted to say that I’ve truly enjoyed browsing your blog posts. After all I will be subscribing to your rss feed and I hope you write again very soon!

    • Thank you. I have become busier of late and the blog is updated less often but I will continue to add new content and there is plenty to be ongoing with, as you have pointed out.
