TL;DR
This study used MOST satellite photometry to observe Regulus (Alpha Leo) over 15 days, finding no eclipses with high precision, contributing valuable data on the star's variability.
Contribution
First high-precision satellite photometry of Regulus to search for eclipses and variability.
Findings
No eclipses detected in 15 days of observation.
Photometry achieved an accuracy of about 0.0005 mag.
Results suggest stability of Regulus during the observation period.
Abstract
No eclipse has been found in 15 days of almost continuous photometry of Alpha Leo with accuracy of about 0.0005 mag.
