Detection of Gravitational Anomaly at Low Acceleration from a Highest-quality Sample of 36 Wide Binaries with Accurate 3D Velocities
K. -H. Chae, B. -C. Lee, X. Hernandez +4
We set out to accurately measure gravity in the low-acceleration range m s from 3D motions of isolated wide binary stars. Gaia DR3 provides precise meas…
Elastic overtones: an equal temperament 12 tone music system with "perfect" fifths
X. Hernandez, Luis Nasser, Pablo Garcia-Valenzuela
The impossibility of a transposable 12 semitone tuning of the octave arises from the mathematical fact that i.e., the second harmonic of the fifth can no…
Dynamical Friction Constraints on the Dark Matter Hypothesis Across Astronomical Scales
X. Hernandez, Pavel Kroupa
Dynamical friction implies a consistency check on any system where dark matter particles are hypothesised to explain orbital dynamics requiring more mass under Newtonian gravity th…
A recent confirmation of the wide binary gravitational anomaly
X. Hernandez, Pavel Kroupa
Concerning recent published studies exploring the presence or otherwise of a gravitational anomaly at low accelerations in wide binary stars as observed by the {\it Gaia} satellite…
Thermodynamics of harmony: extending the analogy across musical systems
L. Nasser, A. Tillotson, X. Hernandez
It is common for most people to think of science and art as disparate, or at most only vaguely related fields. In physics, one of the biggest successes of thermodynamics is its exp…
