RW Aur monitoring requested - ongoing campaign

In 2015 an observing campaign was launched to observe the T Tauri star RW Mon in support of research being carried out by Dr. Hans Moritz Günther. The campaign was extended to request long term monitoring - that request is still active. Please see AAVSO Alert Notice 514 for details and observing instructions. This forum thread is being created now to allow for discussion, etc. (the campaign predated the existence of our forums).

Many thanks, and Good observing,

Elizabeth O. Waagen, AAVSO HQ

I requested AAVSO help for RW

I requested AAVSO help for RW Aur back in 2015. RW Aur continues to be a very interesting target with a lot of changes happening that we don't understand and we don't know when (if ever) it will return to its normal state.

I'm working on a new publication on RW Aur based on new Chandra and AAVSO data from 2018 and 2019 right now. AAVSO data from the campain so far are included in, a few AAVSO observers are co-authors on that paper.

Since we don't know how RW Aur will change in the future, it's important to continue looking! We believe that an accretion event such as this might also trigger outflows in the jet. The jet has several knots, and one theory is that those knots are formed when more material falls onto the star - and "more material onto the star" is observed as a drop in the lightcurve, because this additional material obscures the star.

So, please keep looking and feel free ot post here with any specific questions. I'll update this thread when I learn more!
