K-corrections: an Examination of their Contribution to the Uncertainty of Luminosity Measurements
In this paper we provide formulae that can be used to determine the uncertainty contributed to a measurement by a K-correction and, thus, valuable information about which flux measurement will provide the most accurate K-corrected luminosity. All of this

The Empirical Mass-Luminosity Relation for Low Mass Stars
This work is devoted to improving empirical mass-luminosity relations and mass-metallicity-luminosity relation for low mass stars. For these stars, observational data in the mass-luminosity plane or the mass-metallicity-luminosity space subject to non ...

Luminosity Spectrum Reconstruction at Linear Colliders [PDF]
A good knowledge of the luminosity spectrum is mandatory for many measurements at future e+e- colliders. As the beam-parameters determining the luminosity spectrum cannot be measured precisely, the luminosity spectrum has to be measured through a gauge ...

Luminosity Measurements at the LHC at CERN Using Medipix, Timepix and Timepix3 Devices
The precise determination of the luminosity is essential for many analyses in physics based on the data from the particle accelerator Large Hadron Collider (LHC) at CERN. There are different types of detectors used for the luminosity measurements.

The Stars of Low Luminosity [PDF]
A search has been made among the faint stars with large proper motion found on the Palomar Survey plates for objects that, statistically—judging from their magnitude, color, and proper motion—would appear to be fainter than one ten-thousandth of the sun's luminosity.

Practical Knowledge and Luminosity [PDF]
Many philosophers hold that if an agent acts intentionally, she must know what she is doing. Although the scholarly consensus for many years was to reject the thesis in light of presumed counterexamples by Donald Davidson, several scholars have recently ...
