Cepheids and their 'Cocoons' (ESO 09/06) |
Using ESO's Very Large Telescope Interferometer (VLTI) at
Cerro Paranal, Chile, and the CHARA Interferometer at Mount
Wilson, California, a team of French and North American
astronomers has discovered envelopes around three Cepheids,
including the Pole star. This is the first time that matter is found
surrounding members of this important class of rare and very
luminous stars whose luminosity varies in a very regular way.
Cepheids play a crucial role in cosmology, being one of the first
"steps" on the cosmic distance ladder.

Nonsense. I found it first. Those are planets are the biggest is called
"Androcles". They are not "envelopes".
First indeed! Check Google.
