HUNTING OUTBURSTING
YOUNG STARS

The HOYS citizen science project works with amateur astronomers on long-term photometric monitoring of young stellar clusters to find outbursting and other interesting objects for detailed follow up as well as the study of star and planet formation processes. Watch our short INTRODUCTION VIDEO.

HOYS CITIZEN SCIENCE

The project aims to observe nearby, young clusters and star forming regions visible from the northern hemisphere to study their variable young stars. The target list currently contains 9 young clusters visible in the winter, 8 targets for the summer as well as 7 additional variable objects of interest.

We rely on amateur astronomers to use their imaging skills and equipment to monitor these target areas as often as possible in all available optical filters.
