In an H-R diagram the luminosity or energy output of a star is plotted on the vertical axis. This can be expressed as a ratio of the star's luminosity to that of the Sun; L* / Lsun. Astronomers also use the historical concept of magnitude as a measure of a star's luminosity. Absolute magnitude is simply a measure of how bright a star would ...
There are groups of bright, hot stars and groups of bright, cool stars. There are also groups of dim, hot stars and groups of dim, cool stars. Most stars, including the Sun, plot in a band which runs from the top-left to the bottom-right of the chart. Stars in this area of the chart are in the main-sequence stage of their lives.
Some stars fall in the lower left of the diagram; they are both hot and dim, and must be white dwarfs. Now, think back to our discussion of star surveys. It is difficult to plot an H–R diagram that is truly representative of all stars because most stars are so faint that we cannot see those outside our immediate neighborhood.
6 de feb. de 2023 · UV-dim stars are stars that appear fainter in UV colours with respect to the main bulk of the MSTO stars (specifically, we used the F275W–F438/5W 6). In Section 4 , we reported that the fraction of UV-dim stars for NGC 1850 is ∼7.5 per cent, for NGC 1783 it is ∼10 per cent, while both NGC 1978 and NGC 2121 show a negligible fraction of such stars (dropping to ∼0.5 per cent).
