The GWs from the S-stars revolving around the SMBH at Sgr A*
read the original abstract
A preliminary estimation of gravitational waves (GWs) from the extreme-mass-ratio-inspirals (EMRIs) system in the Galactic Centre (GC) is given for the 37 observed S-stars revolving around the supermassive black hole (SMBH) at Sagittarius (Sgr) A*. Within this century, the total strain of the gravitational waveform calculated from the post-Newtonian (PN) method with eccentricity is well below the current planned sensitivity of pulsar-timing-array (PTA). New technology might be required in order to extract GW signal from this EMRIs system for future PTA detections.

Dark matter energy exchange in stars orbiting supermassive black holes
Orbit-averaged DM energy exchange for S4714 reaches stellar luminosity at σ_χp ~ 10^{-36} cm² (MeV-GeV) and σ_χe ~ 5×10^{-38} cm² (sub-MeV) for spiked DM profiles.
