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.
LIGHT CURVES
Lightcurve of the week 119
This week we have a look at a long term variable star in the P Cyg target field of HOYS. The star in question is V434Cyg, which is classified as [...]
Lightcurve of the week 118
The HOYS winter target that is visible the longest each spring is NGC2264 (The Christmas Tree Cluster). Within it there is a large variety of young and variable stars. Amongst [...]
Lightcurve of the week 117
This week we look at the star BE Ori, in our L1641N target field. This is one of our most southern fields in Orion and has now set for the [...]
Lightcurve of the week 116
This week's featured light curve is not a young star. Instead we are looking at the Mira type variable, KS Cyg. These type of stars are pulsating giants with periods [...]
Lightcurve of the week 115
This week we have a timely look at one of the Gaia photometric alerts. In particular Gaia21bkd, which was published in the evening of March 18. The Gaia light curve [...]
Lightcurve of the week 114
This week we revisit one of the old friends of the light curve of the week feature. The star 2MASS J21383981+5708470 projected onto the target region IC1396A (the Elephant Trunk [...]
Lightcurve of the week 113
This week we have another look at one of the stars from the auxiliary dataset. It is of the star 2MASS J21083418+4656198. There is not much known about the star [...]
Lightcurve of the week 112
This weeks light curve is from our auxiliary dataset, introduced as part of our 100th light curve of the week video. This is a huge set of data taken as [...]
Lightcurve of the week 111
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
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
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
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 [...]
