I am Julia Roquette, a Maître Assistant (Senior Postdoc) in Astrophysics at the Observatoire Astronomique de l'Université de Genève, in Switzerland, where I currently work as part of a Horizon 2020/SPACE project, NEMESIS (Novel Evolutionary Model for the Early Stages of Stars with Intelligent Systems). You can read more about my trajectory here in my Bio.
My main research topic is the formation and evolution of stars similar to our Sun. Throughout my career, I have been exploring this topic using multifaceted research methods, including astronomical observations, numerical models and data science. You can learn more about my research by visiting my Research page.
You can check my full list of publications on NASA/ADS, but here are some highlights:
- Roquette, J., Matt, S. P., Winter, A. K., et al. (2021), The influence of the environment on the spin evolution of low-mass stars - I. External photoevaporation of circumstellar discs, Monthly Notices of the Royal Astronomical Society, 508, 3710.
- Amard, L., Roquette, J., Matt, S. (2020), Evidence for metallicity-dependent spin evolution in the Kepler field , Monthly Notices of the Royal Astronomical Society, 499, 3481.
- Roquette, J., Bouvier, J., Alencar, S. H. P., et al. (2017), Near-infrared time-series photometry in the field of Cygnus OB2 association. I. Rotational scenario for candidate members , Astronomy & Astrophysics, 603A, 106.
I often develop computational codes for my research and use to share the most relevant ones. For example:
-
The Python package
FIREstars(Far- ultraviolet Irradiated Rotational Evolution model for low mass stars) was developed as part of the research presented in Roquette et al. (2021) and includes a compilation of tools for computing rotational evolution numerical models of stars evolving under the irradiation of far-ultraviolet radiation.
I love sequential art and sometimes draw a few comics to help explain my research. You can check some of my Comics page.
