Making Bright Giants Invisible At The Galactic Centre
Pau Amaro-Seoane, Xian Chen, Rainer Schödel +1
Current observations of the Galactic Center (GC) seem to display a core-like distribution of bright stars from inwards. On the other hand, we observe young, massive stars…
Asteroseismic constraints on Asymmetric Dark Matter: Light particles with an effective spin-dependent coupling
André Martins, Ilídio Lopes, Jordi Casanellas
So far, direct detection searches have come empty handed in their quest for Dark Matter (DM). Meanwhile, asteroseismology arises as a complementary tool to study DM, as its accumul…
Probing dark matter crests with white dwarfs and IMBHs
Pau Amaro-Seoane, Jordi Casanellas, Rainer Schödel +2
White dwarfs (WDs) are the most promising captors of dark matter (DM) particles in the crests that are expected to build up in the cores of dense stellar clusters. The DM particles…
Dark matter searches with asteroseismology
Jordi Casanellas
High-precision asteroseismic data provides an excellent opportunity to test theories of stellar evolution and new physics, such as the properties of the dark matter (DM) of the Uni…
Constraints to dark-matter properties from asteroseismic analysis of KIC 2009504
Isa M. Brandão, Jordi Casanellas
Asteroseismology can be used to constrain some properties of dark-matter (DM) particles (Casanellas & Lopes, 2013). In this work, we performed an asteroseismic modelling of the mai…
Stellar convective cores as dark matter probes
Jordi Casanellas, Isa M. Brandão, Yveline Lebreton
The recent detection of a convective core in a main-sequence solar-type star is used here to test particular models of dark matter (DM) particles, those with masses and scattering…
Observing Radio Pulsars in the Galactic Centre with the Square Kilometre Array
R. P. Eatough, T. J. W. Lazio, J. Casanellas +8
The discovery and timing of radio pulsars within the Galactic centre is a fundamental aspect of the SKA Science Case, responding to the topic of "Strong Field Tests of Gravity with…
Identifying the first generation of radio powerful AGN in the Universe with the SKA
Jose Afonso, Jordi Casanellas, Isabella Prandoni +4
One of the most challenging and exciting subjects in modern astrophysics is that of galaxy formation at the epoch of reionisation. The SKA, with its revolutionary capabilities in t…
The Sun and stars: Giving light to dark matter
Jordi Casanellas, Ilídio Lopes
During the last century, with the development of modern physics in such diverse fields as thermodynamics, statistical physics, and nuclear and particle physics, the basic principle…
Constraints on asymmetric dark matter from asteroseismology
Jordi Casanellas, Ilídio Lopes
We report recent results on the impact of asymmetric dark matter (DM) particles on low-mass stars. First, we found that the small convective core expected in stars with masses betw…
First asteroseismic limits on the nature of dark matter
Jordi Casanellas, Ilídio Lopes
We report the first constraints on the properties of weakly interacting low-mass dark matter (DM) particles using asteroseismology. The additional energy transport mechanism due to…
Testing alternative theories of gravity using the Sun
Jordi Casanellas, Paolo Pani, Ilídio Lopes +1
We propose a new approach to test possible corrections to Newtonian gravity using solar physics. The high accuracy of current solar models and new precise observations allow one to…
Signatures of dark matter burning in nuclear star clusters
Jordi Casanellas, Ilídio Lopes
In order to characterize how dark matter (DM) annihilation inside stars changes the aspect of a stellar cluster we computed the evolution until the ignition of the He burning of st…
The capture of dark matter particles through the evolution of low-mass stars
Ilídio Lopes, Jordi Casanellas, Daniel Eugénio
We studied the rate at which stars capture dark matter (DM) particles, considering different assumptions regarding the DM characteristics and in particular investigating how the st…
Towards the use of asteroseismology to investigate the nature of dark matter
Jordi Casanellas, Ilídio Lopes
The annihilation of huge quantities of captured dark matter (DM) particles inside low-mass stars has been shown to change some of the stellar properties, such as the star's effecti…
Low-mass stars within dense dark matter halos
Jordi Casanellas, Ilidio Lopes
We studied the formation and evolution of low-mass stars within halos with high concentration of dark matter (DM) particles, using a highly sophisticated expression to calculate th…
