863-878 (16 pages) ABSTRACT A stellar spectral flux library of wide spectral coverage and an example of its application are presented. The new library consists of 131 flux‐calibrated spectra, ...

The researchers concluded that the estimated hot gas luminosity also underlines the role of continuous star formation as the most likely provider of hot gas replenishment. Summing up the results, the ...

The brighter the star is overall, the longer the period of luminosity. Since the cepheids in the Magellanic Clouds were all about the same distance from Earth, Leavitt concluded that the period ...
