This week we look at the light curve of the variable star V718Per. It is situated in the IC348 target region and is a bona fide cluster member. It has [...]

This week we continue to look at our analysis of the entire sample of young stars in HOYS. This time we look at their mid-infrared colours measured by the WISE [...]

In many of our papers with HOYS data you find introductory statements like this one: "Historically, young stars were first discovered based on their irregular and large-amplitude optical variability (Joy [...]

In our "tour of HOYS papers", while we are recovering the data base to look at new, interesting light curves, we have a look at a figure from our second [...]

While we are still working on restoring our server (update to follow next week), we have a look on a plot from the first published referee paper using HOYS data. [...]

While we are still repairing the server hard disks, we look at some interesting technique of analysing our light curves. We call this variability fingerprinting. The young star light curves [...]

This week we have a look at some light curves presented in our latest paper "A survey for variable young stars with small telescopes: VI - Analysis of the outbursting [...]

While the database is still off-line for server repairs, we have another look at some early results of the ongoing data analysis. Today we look at the young T-Tauri star [...]

This week we look at the light curve of LkHa137. This is a young star in the Pelican Nebula region. It is situated in a dark part of the molecular [...]
