Using NASA's Transiting Exoplanet Survey Satellite (TESS), an international team of astronomers has detected solar-like oscillations and ellipsoidal variations in the light curve of a binary system known as 12 Boötis (or ...
The quantum vibrations in atoms hold a miniature world of information. If scientists can accurately measure these atomic oscillations, and how they evolve over time, they can hone the precision of atomic clocks as well as ...

Two different waves with the same frequency and wavelengths can be coupled, so that the amplitude alternates periodically between the two to form a phenomenon known as a coherent beating oscillation. The process can be observed ...
Using ESA's XMM-Newton telescope, Indian astronomers have performed X-ray observations of a binary X-ray pulsar known as LMC X-4. The observational campaign resulted in the detection of quasi-periodic oscillations (QPOs) ...
Neutrinos may be the key to finally solving a mystery of the origins of our matter-dominated universe, and preparations for two major, billion-dollar experiments are underway to reveal the particles' secrets. Now, a team ...

Volcanic eruptions, not natural variability, were the cause of an apparent "Atlantic Multidecadal Oscillation," a purported cycle of warming thought to have occurred on a timescale of 40 to 60 years during the pre-industrial ...

Using NASA's NuSTAR and Swift space observatories, Indian astronomers have inspected an X-ray pulsar known as XTE J1858+034 during its outburst and identified a low-frequency quasi-periodic oscillation (QPO) from this source. ...
Using data from the Rossi X-ray Timing Explorer (RXTE) satellite, astronomers from the Florida Institute of Technology have discovered a quasi-periodic oscillation (QPO) in the galaxy NGC 4945. The finding, reported in a ...
