In this talk I will firstly give a brief introduction on what bosonic stars are and why should we be interested in studying them. Then, I will present a study of the non-linear dynamics of both boson(scalar) and Proca(vector) stars, through numerical relativity techniques. I will depict three different physical scenarios.
The CIDMA research unit meeting 2020 took place on the 22-23 January at the Mathematics Department of Aveiro University. João Oliveira and Sonia Anton were the two Gr@v representatives in the scientific programme.
Penrose process remains a textbook example of a mechanism for energy extraction from black holes, yet there are many impediments to its practical viability. The longest known problem is that it requires a particle to split into two fragments with very high relative velocity.
Tomohiro Nakamura, a PhD student from Nagoya University is visiting Gr@v until the end of January 2020. Masato Minamisuji, from IST-Lisbon, visted for 8-10 January 2020 for scientific collaboration. In the photo with Taishi Ikeda whose visit overlapped with that of Masato's and Tomohiro's.
Our group coordinated the "Numerical Relativity and High Energy Physics" IRSES network (2012-2015). Here is a list of the global network meetings organized:
