Description
In this work we present the properties of gravitational waves emitted
from the f-mode oscillation of a compact star corresponding to the
Object HESS J1731-347 as a Twin Compact Star, a hybrid neutron star with
the same mass as a larger, purely hadronic neutron star. HESS J1731-347
is a peculiar object due to its reported compactness consisting of a
mass of 0.77 solar masses and a radius of 10.4 km. Gravitational waves
carry information of the damping time of the f-mode and are though to be
associated to pulsar glitches, thus providing the possibility of a
upcoming multi-messenger observation performed by future gravitational
waves observatories like the Einstein Telescope or the Cosmic Explorer.
