Tkachenko waves, glitches and precession in neutron star
, 2008 Here I discuss possible relations between free precession of neutron stars, Tkachenko waves inside them and glitches. I note that the proposed precession period of the isolated neutron star RX J0720.4-3125 (Haberl et al.

Pseudo-Newtonian Potentials for Nearly Parabolic Orbits [PDF]
, 2012 We describe a pseudo-Newtonian potential which, to within 1% error at all angular momenta, reproduces the precession due to general relativity of particles whose specific orbital energy is small compared to c^2 in the Schwarzschild metric.

Pulsar state switching, timing noise and free precession [PDF]
, 2011 Recent radio pulsar observations have shown that a number of pulsars display interesting long term periodicities in their spin-down rates. At least some of these pulsars also undergo sharp changes in pulse profile.

Resonant relaxation in protoplanetary disks [PDF]
, 1998 Resonant relaxation is a novel form of two-body relaxation that arises in nearly Keplerian disks such as protoplanetary disks. Resonant relaxation does not affect the semimajor axes of the particles, but enhances relaxation of particle eccentricities and

Precession-band variance missing from East Asian monsoon runoff
Nature Communications, 2018 Speleothem CaCO3 δ18O is a commonly employed paleomonsoon proxy. However, inferring local rainfall amount from speleothem δ18O can be complicated due to changing source water δ18O, temperature effects, and rainout over the moisture transport path.

Lense-Thirring Precession in Pleba\'nski-Demia\'nski spacetimes
, 2013 An exact expression of Lense-Thirring precession rate is derived for non-extremal and extremal Pleba\'nski-Demia\'nski spacetimes. This formula is used to find the exact Lense-Thirring precession rate in various axisymmetric spacetimes, like: Kerr, Kerr ...

Twenty Years of Timing SS433 [PDF]
, 2001 We present observations of the optical ``moving lines'' in spectra of the Galactic relativistic jet source SS433 spread over a twenty year baseline from 1979 to 1999.

Spin Precession Experiments for Light Axionic Dark Matter [PDF]
, 2017 Axion-like particles are promising candidates to make up the dark matter of the universe, but it is challenging to design experiments that can detect them over their entire allowed mass range.
