We are back with our HOYS-LCO program for next Winter (2025/26). If you want to get your pupils involved apply now on the website: hoys.space/lco-project/ Please share this if you have any teacher contacts that might be interested. 🔭

This week we are following up two posts from weeks 268 and 306. These were about the star that seemed to have two periods in close proximity to each other. hoys.space/lightcurve-o... 🔭

This week marks the 6th anniversary of our light curve of the week feature! To ‘celebrate’ we show one of the less remarkable light curves, that do not get much attention usually. hoys.space/lightcurve-o... 🔭

This week we look at the young star TT Ori, which is situated just North of the Orion Nebula M42. It was flagged up by Gaia as an alter (Gaia22ehy) some years back.🔭 hoys.space/lightcurve-o...

This week we have a look at an old friend of this feature, the variable V350Cep in the NGC7129 cluster. ... Since two years now the source has changed its behaviour! 🔭 hoys.space/lightcurve-o...

Remember the object Gaia24ala which we posted about in week 266? It got flagged up by Gaia due to a sudden drop in brightness on top of a longer term dimming event, making it about 2mag fainter at about JD=2460335 – late January, 2024. hoys.space/lightcurve-o... 🔭

Welcome to the 300th light curve of the week post!!!!! 🙂 That is now almost 6 years of weekly posts. We started that feature on January 7th, 2019 🔭 hoys.space/lightcurve-o...

This week we have look at the light curve of the young variable star GM Cep. It is situated in the elephant Trunk Nebula target region, and we have looked at it a few times before. 🔭 hoys.space/lightcurve-o...

With the start of our new HOYS-LCO project for this year imminent, we have a look at another image of one of our HOYS target regions. This week we feature the Elephant Trunk Nebula, or IC1396A. This ‘globule’ is part of a much larger HII region... 🔭 hoys.space/lightcurve-o...

This week we look at the light curve of the namesake of one of our target fields, the young star V555Ori, which is situated about a degree North of the Orion Nebula. It was flagged up in 2017 as a variable Gaia17afn... 🔭 hoys.space/lightcurve-o...

This week we look at the R and B-Band light curve of the young star AHOri, situated just North of the Orion nebula. 🔭 hoys.space/lightcurve-o...

This week we have another look at the fascinating case of the young star KH15D, or V582Mon. It is situated near the Cone Nebula, just south of the NGC2264 cluster.🔭 hoys.space/lightcurve-o...

HOYS stands for Hunting Outbursting Young Stars and one of our aims from the start was to provide long term, pre-outburst light curves for the largest of the known bursts, the FU-Ori type outbursts. 🔭 hoys.space/lightcurve-o...
