Week 6

Marcos V -

Hello and welcome to week 6 of my project!

This week I experienced a pretty significant setback. In order to perform an analysis of Zeeman splitting, like I intended, my data needs to include circular polarization data, so that I can compare the shifts between right and left polarization. Despite an extensive search, I was not able to find any observational data of V Hydrae including circular polarization data. This means that right now I am unable to conduct the Zeeman analysis. However, I will continue searching for suitable data; even a little bit would go a long way towards calculating the magnetic field strength around V Hydrae’s plasma ejections.

In the meantime, I will move on to my next analysis of the outflow vectors. I plan to use a simpler kind of polarization image to model the structure of the magnetic field by overlaying a polarization vector map onto an image of the plasma outflows using a software called DS9. I can then compare the structure to the shape of the actual plasma ejections, and the relationship between their shapes will provide insight into how they interact and how the magnetic field shapes and directs the plasma. Right now I am still searching for a suitable dataset, but the program for this analysis should be simpler than the previous one, so the process should go a little quicker.

This change is unexpected and sudden, and I am still trying to get back into a good momentum, but as always feel free to ask any questions, and thanks for reading!

    Hi Marco, sounds like you are pivoting and handling it well. Do you have any insight into why this specific data is so hard to find?

    Hi Ms. Bennett, good question. It would seem that this system just isn't very interesting to a lot of astronomers. The nearby system TW Hya attracts a lot of attention, and my searches often result in data for neighboring systems.
