Variable stars magnitudes estimations exploiting the eye physiology

TL;DR

This paper introduces a novel astronomical method for estimating star magnitudes by leveraging the eye's dark adaptation physiology, specifically the rhodopsin cycle timing, applicable to bright stars and telescopic observations.

Contribution

The paper presents a new technique for star magnitude estimation based on eye physiology, expanding observational methods beyond traditional photometry.

Findings

Effective for bright stars like Betelgeuse and Antares

Applicable to stars at the telescope's limiting magnitude

Discusses the method's limitations and scope

Abstract

The physiology of the dark adaption process of the eye is revisited from an astronomical point of view. A new method for the magnitude estimation of a star is presented. It is based upon the timing of the physiological cycle of the rhodopsin during the eye dark adaption process. The limits of the application of the method are discussed. This method is suitable for bright stars as Betelgeuse, Antares or Delta Scorpii or stars at the limiting magnitude observed with a telescope.
