Description

Low-mass asymmetric dark matter (DM) particles are appealing DM candidates that are not detectable with most indirect DM searches. However, these particles may efficiently accumulate in the core of low-mass stars, reducing their central temperatures and inhibiting the formation of small convective cores in 1.1-1.3 M${}_{\odot }$ stars, thus leaving a characteristic signature in the low-degree modes of the stellar oscillations. Here I will present the first asteroseismic constraints to the properties of these DM particles, obtained comparing the oscillations of Alpha Cen B with modified stellar models. To conclude, I will discuss the prospects of using this approach with targets of the Kepler mission such as red giants and stars with detected convective cores.
