About me
Hi there! As you can see above, this page is a description of me, Stan Barmentloo. Since september 2022 I live here in lovely Stockholm and I have the pleasure of working with my favorite interest: astronomy! More specifically, I work in the supernova modeling group of Anders Jerkstrand. Here, I search answers to questions related to evolution of the most massive stars, by modeling what the spectra of the supernovae of these stars look like. I undertake this quest as part of the ePESSTO+ and ZTF collaborations, which collect large amounts of observations of these greatest of explosions.
If you want to reach out/have a question about my work (or want to talk about history, linguistics, or cultivating vegetables, anything really :) ), please shoot an e-mail!
Research
The first research project of my PhD studied the emission of nitrogne in stripped envelope supernovae (SESNe), through the [N II] 6548, 6583 doublet. By modeling this emission for progenitors with different masses, we were able to use this emission to derive a diagnostic for SN progenitor mass. This diagnostic was applied to a sample of observed SNe, and can in fact be used by anyone studying nebular phase spectra of SESNe, without the need of creating their own models.
The full study can be found here.
