The star T Ori has featured a few times in this feature. For example in weeks 101 and 248. The star shows dimming events at irregular intervals and each observing season appear different.
Thus, in the above plot we show the light curve of the first half of the current Observing season – basically August to December 2025 – in the I-Band. We can see that this typical behaviour has not changed. There are variations of up to 0.8mag visible and dimming events vary in duration and depth.
These variations are usually caused by clumpy, small scale structures in the inner disk which pass along the direct line of sight to the central star. The statistics of the timescales and amplitudes of the variations can hence tell us about the structure of the inner disk.
