abstract = "The direct detection of gravitational waves (GWs) opened a new
chapter in the modern cosmology to probe possible deviations from
the general relativity (GR) theory. In the present work, we
investigate for the first time the modified GW form propagation
from the inspiraling of compact binary systems within the context
of fðTÞ gravity in order to obtain new forecasts/constraints on
the free parameter of the theory. First, we show that the modified
waveform differs from the GR waveform essentially due to induced
corrections on the GWs amplitude. Then, we discuss the forecasts
on the fðTÞ gravity assuming simulated sources of GWs as black
hole binaries, neutron star binaries and black holeneutron star
binary systems, which emit GWs in the frequency band of the
Advanced LIGO (aLIGO) interferometer and of the third generation
Einstein Telescope (ET). We show that GW sources detected within
the aLIGO sensitivity can return estimates of the same order of
magnitude of the current cosmological observations. On the other
hand, detection within the ET sensitivity can improve by up to 2
orders of magnitude the current bound on the fðTÞ gravity.
Therefore, the statistical accuracy that can be achieved by future
ground based GW observations, mainly with the ET detector (and
planed detectors with a similar sensitivity), can allow strong
bounds on the free parameter of the theory, and can be decisive to
test the theory of gravitation.",
