Some of these "hyper-giants" may in fact be very tight clusters of hot, massive stars surrounded by gas. Eta Carinae has been imaged to multiple IR sources.

Yes, that is possible. But you're wrong about Eta Carinae. It is a single (or double) star, that is known. If I remember correctly, Hubble resolved S Doradus into multiple stars in the early 1990s. Still, S Dor is one of the largest stars known, but not impossibly massive as thought earlier (over 1000 M_Sun).--Jyril 20:20, 18 March 2006 (UTC)

[edit] Clarification

According to the article,

Hypergiants are the most luminous stars, thousands to millions of times the solar luminosity; however, their temperatures vary widely between 3,500 K and 35,000 K.

This sentence seems to be saying that there's a relationship between luminosity and temperature in hypergiants that isn't what you would expect. E.g., maybe you would think that a hypergiant would be really hot, but some are only 3,500 K. Is that one of the ideas? I don't feel competent to add this clarification. modify 17:16, 24 June 2006 (UTC)

I assume this is referring the the surface tempereature. The surface of the sun is 5,780 K, but it has a much smaller surface area. — Daniel 21:00, 6 July 2006 (UTC)

[edit] Size

This article doesn't give a lower limit for a hypergiant's mass. According to the Supermassive star article, stars with masses greater 60 solar masses are hypothetical (one solar mass is equal to the mass of the sun). — Daniel 21:00, 6 July 2006 (UTC)
