Second, we used curved crystal spectrometers, which have the advantage of high spectral resolution and high luminosity.
This is also required to avoid the ablation plasma flow around the foil edges, which otherwise disturbs the luminosity record.
These changes are transmitted to the outer regions of a star, which results in a steady increase in luminosity and changes in effective temperature.
Measurements of luminosity in affected individuals typically reveal a scotopic function at dim background levels.
A higher luminosity can obviously be preferential for the number of experimental events.
The stellar mass and metallicity, and the initial values of luminosity, effective temperature, core temperature and core pressure were individually set.
Stellar distances and luminosities were calculated using the above data and procedures described in the text.
The luminosity evolution of the main-sequence central star is deduced by polynomial fitting of stellar evolution models.
