HOYS Citizen Science2020-11-27T10:41:30+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 98

24 November 2020|

This week we focus on a star in one of the least often observed  HOYS target fields. The light curve shown in the above image is of the star V1787Ori. [...]

Lightcurve of the week 97

19 November 2020|

This week we have a look at the star V982Cep. It is situated in the field of NGC7129. With a most likely distance from Gaia of 734pc, the star is [...]

Lightcurve of the week 96

11 November 2020|

This week we have a detailed look at the light curve of V505Ori. This is one of the three targets in the Sigma Ori field observed by HOYS, which we [...]

Lightcurve of the week 95:

5 November 2020|

We are "celebrating" the start of UK lock-down Nr.2 (at least there are lots of fireworks outside 😊), so let's look back at the light curve of the week Nr. [...]

A HOYS participant perspective

Six years of working with amateur astronomers – an ongoing success story By: Dirk Froebrich, PI of the HOYS Project This article was originally published in Spanish in the magazine [...]

A HOYS participant perspective

28 October 2020|

HOYS contributor, Mark Phillips, explains how he has tried to automate as much of the process of acquiring HOYS data and processing it as possible. What do you do?

Lightcurve of the week 94:

27 October 2020|

For this weeks light curve we stay in the field of Sigma Ori. Indeed this area on the sky contains a large number of variable young stars which are part [...]

Lightcurve of the week 93:

20 October 2020|

This week we actually have a look at three different light curves. They are of the stars V505Ori, V510Ori, and TX Ori. These are all situated in the target area [...]

Lightcurve of the week 92:

16 October 2020|

Similar to last week we have a look back at an object that has featured before. This week it is the variable star V350Cep. The star is situated just north [...]

Lightcurve of the week 91:

9 October 2020|

This week we have a look back at an 'old friend' of the HOYS project, the unusual variable V2492Cyg. It has featured a few times as light curve of the [...]

Lightcurve of the week 90:

1 October 2020|

This week we look at the star OT Mon near the Cone Nebula. The object is a known T-Tauri star and the light curve shows that it is variable on [...]

Lightcurve of the week 89:

23 September 2020|

This week we have another look at the light curve of the long period variable V1376Cyg. This is a background giant star (Gaia distance about 4100kpc - or 13000 light [...]
