We once thought that dark matter might be made up of large objects such as black holes or exotic types of faint stars — neutron stars or white dwarfs — that are nearly invisible to our telescopes.
But von Hippel, Gilmore and their colleagues used the Hubble Space Telescope, and this allowed them to identify and measure the temperature of white dwarfs as faint as 25th magnitude, which is about 100 million times fainter than any star visible with the naked eye.
Maybe it was just large accumulations of dim but familiar objects, like extremely faint red stars or white dwarfs, some astronomers speculated.
«Our final image should show us a companion 100 times fainter than any other white dwarf orbiting a neutron star and about 10 times fainter than any known white dwarf, but we don't see a thing,» team member Bart Dunlap, a graduate student from the University of North Carolina at Chapel Hill, said in a statement.
«You can see bulges in distant galaxies, but you can not resolve the very faint stars, such as the white dwarfs.
For a time, observers believed that Gacrux had a faint, bluish white (A3 V) binary companion lying within two minutes of arc that is still designated in the SIMBAD Astronomical Database and the Yale Bright Star Catalogue, 1991 5th Revised Edition as Gamma Crucis B (HR 4764 or HD 108925).
A new analysis of galaxy colors, however, indicates that the farthest objects in the deep fields must be extremely intense, unexpectedly bright knots of blue - white, hot newborn stars embedded in primordial proto - galaxies that are too faint to be seen even by Hubble's far vision — as if only the lights on a distant Christmas tree were seen and so one must infer the presence of the whole tree (more discussion at: STScI; and Lanzetta et al, 2002).
For about two weeks the star could be seen in daylight, but at the end of November it began to fade and change color, from bright white over yellow and orange to faint reddish light, finally fading away from visibility in March, 1574, having been visible to the naked eye for almost 16 months (more about Brahe's «acid tongue and silver nose,» the cultural shock of the «new star,» and how supernovae create high - energy radiation from Wallace H. Tucker).
During that night, the scientists were able to measure the changing Doppler shift of the star NLTT 11748 as it orbited its faint, but more massive, white dwarf companion.
As a highly evolved and relatively cool orange - red giant, single star, Pollux is not much like its «twin» star Castor, which is actually composed of three sets of binary stars (as many as four bluish - white, main sequence stars with two fainter companions).
When this happens, smaller stars expand into what astronomers call red giants, then shrink into faint white dwarfs, according to NASA.
A 1997 paper by astronomers (Henry et al) associated with the Research Consortium on Nearby Stars (RECONS) suggests that the sample of stars known to lie within 10 parsecs (32.6 ly) of Earth is «woefully incomplete,» particularly in faint red (M) dwarfs and «white» dwStars (RECONS) suggests that the sample of stars known to lie within 10 parsecs (32.6 ly) of Earth is «woefully incomplete,» particularly in faint red (M) dwarfs and «white» dwstars known to lie within 10 parsecs (32.6 ly) of Earth is «woefully incomplete,» particularly in faint red (M) dwarfs and «white» dwarfs.
