New Light Curves and Orbital Period Investigations of the Interacting Binary System UV Piscium
Journal of Astronomy and Space Sciences, 2019 UV Psc is a typical RS CVn type system undergoing dynamic chromosphere activity. We performed photometric observations of the system in 2015 and secured new BVR light curves showing well-defined photometric waves.

Luminosity and photometry [PDF]
Proceedings of the Royal Society of London, 1897 The luminosity of the spectrum was determined by what may be term ed the method of the “minimal effective stimulus.” Through the partition separating two dark rooms from each other a hole was drilled 1 mm. across; this was covered with a piece of ground glass.
