Data for Dipole Boson Stars
Here, numerical data described in the paper "Two boson stars in equilibrium", arXiv:2210.01833, is made available for public use.
The attachment "Data_files.zip", contains the data files:
- configuration-I.dat
- configuration-II.dat
- configuration-III.dat
These files correspond to the three representative dipolar BS (DBS) solutions among those described in the paper above. These solutions are:

Gr@v member Ivo Sengo was one of the participants in the 4th Physics Conference of Portuguese-Speaking Countries – 4CFPLP, that took place in Cape Verde, from 12-16 September 2022. Ivo delivered a contributed talk on "Black hole shadows".
Visits of K. Uzawa and Z. Belkhadria
Our collaborator Kunihito Uzawa from Japan together with Zakaria Belkhadria, a Ph.D. student from U. Cagliari, Italy, are our guests this week. Zakaria is visiting us within a short term scientific mission of the COST action CA18108.
Elastic compact objects in General Relativity
Speaker
Guilherme Raposo (CIDMA-UA)
Event date
Venue
Hybrid Sala Sousa Pinto (Math dpt) and Zoom
Event Website
Event type
In this seminar I will introduce a rigorous and general framework to study systematically self-gravitating elastic materials within general relativity. The formulation that will be presented in this seminar is particularly suitable to investigate the existence and viability, including radial stability, of spherically symmetric elastic stars.
New mechanism of primordial black hole formation during reheating
Speaker
Luis Padilla (UNAM, Mexico)
Event date
Venue
Online (only)
Event type
In this talk, we consider a scenario in which an extended reheating scenario can be described analogously to the so-called scalar field dark matter model.
3rd Workshop on Compact Objects, Gravitational Waves and Deep Learning
The 3rd Workshop on Compact Objects, Gravitational Waves and Deep Learning will take place on 23 Sep 2022 at the University of Minho, after the first and second workshops of this series in Aveiro and Valencia, repectively.
Física 2022
Gr@v member C. Herdeiro was one of the invited speakers of "Física 2022" the 23rd national conference of the Portuguese Physics Society, delivering the talk "Buracos Negros: de uma equação ao Nobel" (photo courtesy of A. Folhas).
See you soon Alexandre!
We bid farewell (with a Peruvian flavour) to Alexandre Pombo, that will join Charles University in Prague for his next post-doctoral position. See you soon Alexandre!
