HOYS Citizen Science2021-02-27T19:14:41+00:00


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.



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.

Lightcurve of the week 111

26 February 2021|

One of the ongoing science projects with the HOYS data is the search for periodic variables in the Pelican Nebula. Here we show one of the easiest to find, characterise [...]

Lightcurve of the week 110

20 February 2021|

This week we have a rare look at a southern hemisphere target. The star of interest is in the field around Gaia19eyy, a regularly erupting HerbigAeBe star - but this [...]

Lightcurve of the week 109

10 February 2021|

This week we look at the light curve of the star PR Ori (or so one might think). But let's start at the beginning and work through the 30min of [...]

Lightcurve of the week 108

5 February 2021|

This week we investigate the (rather boring looking) light curve of the star BD+65 1636. It is classified as a young stellar object with a spectral type of B8, so [...]

Lightcurve of the week 107

28 January 2021|

This week we look at the star V582Cep, situated in the NGC7129 target field. This target field usually gets a higher number of observations at the current time of the [...]

Lightcurve of the week 106

22 January 2021|

On  the face of it, the long term V, R and I data of 2MASS 20512895+4404230 (1st image) looks ordinary and boring. No visible change, just a bit of noise. [...]

HOYS-LCO Project Update – New Target

17 January 2021|

The HOYS-LCO project is progressing well. In total we have had now 35 people applying to participate. Over the last 6months we have taken 60 sets of 3x2min B,V,R images [...]

Lightcurve of the week 105

13 January 2021|

This week we look at V591Ori. This is another of the young stars situated in the L1641N cloud in Orion. At a distance of 293pc, this objects is relatively nearby, [...]

Lightcurve of the week 104

6 January 2021|

This week we look at V1144Ori. It is situated in what used to be one of our least observed target regions - L1641N in Orion. It is situated just South [...]

Lightcurve of the week 103

1 January 2021|

Happy New Year everyone! We start 2021 with a look at the light curve of AA Ori. This is a know variable star in the southern outskirts of the Orion [...]

Lightcurve of the week 102

24 December 2020|

Happy Christmas everyone! This weeks light curve is of the the star GP Mon in the Christmas Tree Cluster NGC2264. It is a know variable star of Orion Type at [...]
