View Full Version : What did IRAS find?

2010-May-08, 05:13 PM
CTs mention a Washington Post article (http://http://planet-x.150m.com/washpost.html) where IRAS find a mysterious object in infra-red.

Phil Plait explains that IRAS findings turned up not being rogue planets, but gas clouds or galaxies. However, I would like to find what exactly was that one object from the Washington Post.

I searched in internet, and I suppose it was the Becklin-Neugebauer object (http://http://en.wikipedia.org/wiki/Becklin-Neugebauer_Object). Could anyone confirm this?

The link does not work.

Do you mean the 1983 story? Maybe this?

Maybe this may help.

Here is a short information given:


It seems to be that Washington Post was referring to

"Unidentified point sources in the IRAS minisurvey" by: Houck, J. R.; Soifer, B. T.; Neugebauer, G.; Beichman, C. A.; Aumann, H. H.; Clegg, P. E.; Gillett, F. C.; Habing, H. J.; Hauser, M. G.; Low, F. J. in: Astrophysical Journal, Part 2 - Letters to the Editor (ISSN 0004-637X), vol. 278, March 1, 1984, p. L63-L66.


On page L64 there is a short list of unknown sources, but positions given here does not match with Beckin-Neugebauer-Object at all.

This is:

"One of the most powerful infrared sources known, located in the Kleinmann-Low Nebula behind the Orion Nebula, and discovered by Eric Becklin and Gerry Neugebauer in 1967. Its position is RA 05 h 35.2 m, dec. -05 22'. It is thought to be a very young and massive B star embedded in a dense expanding dust envelope which absorbs the star's visible light and re-emits it in the infrared."
