HOYS Publication Guidelines
All publications using any HOYS data should reference the project description paper (Froebrich et al. 2018, MNRAS, 478, 5091) and the data calibration paper (Evitts et al. 2020, MNRAS, 493, 184). If not all contributors of data are included in the author list, then the following should be added to the acknowledgements of every publication: “We would like to thank all contributors of observational data for their efforts towards the success of the HOYS project.”
We aim to disseminate the results of the science exploitation of the HOYS data with two kinds of publications. These are: i) larger, survey description type publications and ii) smaller, more specific publications.
We plan to write type i) publications about every one to two years. On these publications every participant who contributed data should be added as a co-author (if s/he wishes so), as well as everyone involved in the data analysis.
All other, type ii) publications using any HOYS data should include everyone as a co-author who made a significant contribution to the scientific analysis of the data and the preparation of the publication. Furthermore, any contributor who made a significant contribution to the dataset analysed in the publication should be added as co-author. In other words, anyone whose data cannot be removed without significantly degrading the quality of the analysis should be made a co-author.

Happy New Year and Happy 4th Birthday to our light curve of the week feature! This week we finish our round of thanks to participants to the HOYS project. We [...]
Lightcurve of the week 207
This week we continue our round of thanks to participants to the HOYS project. We have a short description of the group at the Astrolab IRIS observatory in Belgium, who [...]
Lightcurve of the week 206
I have been thanking our contributors to the project many times in the past. In most cases this has been very general and 'anonymous' without mentioning any specific names. Indeed [...]
Lightcurve of the week 205
This week we look at a Gaia alert from a few years ago in the HOYS field L1641N. The object in question is Gaia19amy, or otherwise known as the variable [...]
Lightcurve of the week 204
This week we have a short outlook on some general statistical analysis we are working one. As mentioned before, we have used the latest Gaia data release to identify all [...]
Lightcurve of the week 203
This week we are looking at the light curve with probably the least amount of data points we ever had in this feature - now almost at it's 4th anniversary. [...]
Lightcurve of the week 202
This is the first time we are looking at the same star twice in two weeks, i.e. we have another more detailed look at the light curve of the variable [...]
Lightcurve of the week 201
This week we look at the light curve of the variable star V1787Ori. It is situated South of the Orion Nebula in the HOYS target field called L1641N. This is [...]
Lightcurve of the week 200
This weeks special edition of the light curve of the week comes in form of a short video thanking all the participants for their tireless contributions.
Lightcurve of the week 199
This week we look at the newly announced Gaia altert object Gaia22ehy, which is situated north of the Orion Nebula Cluster. The object is also know as the variable star [...]
Lightcurve of the week 198
As mentioned a few times in the past, one of the goals of HOYS is to characterise how the typical young star is varying. We have started to prepare the [...]
Lightcurve of the week 197
This week we keep with 'tradition' and look at one of the recently (yesterday, October 18) announced Gaia photometric alerts in one of our target fields. The source in question [...]
