HOYS Citizen Science

Newsletter Contents

Sending this out to subscribers who were missed off the first sending - apologies.
The project has seen quite some progress and changes over the past few months. This includes our new web-page and newsletter system. This is the first of the newsletters. It will inform you about the the following:
A general project update; News about data and observations; Our new website and social media presence; Research news.

General Project Update

HOYS is now run by a small group of professional Astronomers, Amateur Participants, one outreach person and one teacher. We have monthly discussion meetings about the project. If you have any suggestions regarding the project please get in touch and let us know. If you are keen to join the team, please don't hesitate to come forward.
Since July 1st we are working together with the Las Cumbres Observatory (LCO) as one of their Global Sky partners. This means we have been given 60hrs of observing time on their network of 0.4m telescopes to use for educational projects. We have started to use this time to give amateurs without observing equipment the chance to contribute data to HOYS. We will also develop educational material to teach participants how to analyse HOYS light curves. If you know anyone interested in this, please point them to our application page.
Due to the Covid situation some of our planned talks about the project had to be postponed. We have now started to move some of them online. Videos of those are already in part available on our YouTube page. We have three further talks scheduled during early September.

HOYS Data and Observations

We have now collected just over 29500 images and stored in excess of 137 million brightness measurements in our database.
The first of the winter targets (in Perseus) have now become available again. Please, as usual, try to observe all the targets in all filters as often as possible.
During August, as every year, we try to especially focus on IC5070. Please make this a priority for the month as often as possible. In particular, if you have the opportunity to obtain deep H-alpha images of the region, that would be appreciated. We are collecting these data to eventually study the long term variability in the H-alpha line of the stars.
We have also successfully obtained 33 hours of observing time for the project on the 2m Liverpool Telescope. This will be used for a detailed study of the object KH15D in NGC2264. From October 1st to the end of March we will do nightly photometry of the region around the source in U, B, V, R, I, and H (1.65mu). We hope that HOYS participants can contribute deep H-alpha images of the source during this time.
One of our participants has obtained observing time for the project via a proposal for time at the AAVSOnet initiative of the American Association of Variable Stars Observer’s robotic observatories. Well done to Juan-Luis!
Our above mentioned LCO time has been used to obtain B, V, R images of the Cocoon Nebula (IC5146) roughly every three days. We plan to keep observing the same target over most of the year to build a nice coherent data set from this facility.

Webpage and Social Media

Our brand new web-page is now available at hoys.space. We are using this now as the main source for disseminating information. We are continuing the light curve of the week posts - originally just placed on Facebook. Any feedback on the page is very welcome!
In parallel to the HOYS Facebook group, we have also set up a HOYS Twitter account. Please help publicising the project by liking, sharing and retweeting posts about the project. We also strongly encourage everyone to contribute their own posts about anything project related.
Related to this, we would like to get participants to write their own posts for the website, similar to the first example we published a few weeks ago. If you are interested in doing this, please get in touch.
Finally: The domain name and website hosting is costing some money. The first year funding has been sponsored by Marks company Cygnus Extra. If you would like to sponsor the website and domain in the future, please let us know.

Publications and Research

The analysis of the data you are contributing is continuing all the time.
We have had our paper on the source V1598Cyg accepted for publication in Monthly Notices of the Royal Astronomical Society. It should be published soon.
As mentioned before, the detailed work on the analysis for the next paper has now fully started. We plan to identify all young stars in the Pelican Nebula region that show measurable rotation periods and analyse their properties. As for the paper on the source V1490Cyg, we plan to include everyone who contributed data used in the analysis as a co-author. We will be in touch with everyone in due time.
Starting this September, I will have a new PhD student. The task of the student will be to work on investigating to rotation of young stars and the properties of spots on their surface.
We also encourage everyone to start doing their own investigations using HOYS data. As part of our work with the LCO, we have started to create some videos that explain how to analyse our data. We will expand these videos to more topics over the next few months. If you have found an interesting object, please try to share your findings with us or even try to publish your work in an amateur journal. We have several experienced people amongst our participants who are in principle able to help and advise you on this.
