Long timescale dynamics of spin textures in a degenerate F=1 $^{87}$ Rb spinor Bose gas
Long timescale dynamics spin textures Rb spinor Bose gas
2011/8/17
Abstract: We investigate the long-term dynamics of spin textures prepared by cooling unmagnetized spinor gases of F=1 $^{87}$Rb to quantum degeneracy, observing domain coarsening and a strong dependen...
Non-convergence of the critical cooling timescale for fragmentation of self-gravitating discs
accretion accretion discs protoplanetary discs planets and satellites
2010/11/10
We carry out a resolution study on the fragmentation boundary of self-gravitating discs. We perform three-dimensional Smoothed Particle Hydrodynamics simulations of discs to determine whether the crit...
Multi-timescale Solar Cycles and the Possible Implications
Solar cycle — Sun extrapolation — Sun flares
2010/11/11
Based on analysis of the annual averaged relative sunspot number (ASN) during 1700 – 2009, 3 kinds of solar cycles are confirmed: the well-known 11-yr cycle (Schwabe cycle), 103-yr secular cycle (numb...
Testing seawater Sr isotopic variability on a glacial-interglacial timescale: An application of latest high-precision thermal ionization mass spectrometry
TIMS Sr isotopes seawater glacial-interglacial cycle
2017/8/9
Stability in seawater 87Sr/86Sr ratios over a glacial-interglacial timescale has gained the consensus, yet inter-site inconsistency exists in the previous data employed for validation of this issue. T...
Climate spectrum estimation in the presence of timescale errors
Climate spectrum estimation presence of timescale errors
2009/10/30
We introduce an algorithm (called REDFITmc2) for spectrum estimation in the presence of timescale errors. It is based on the Lomb-Scargle periodogram for unevenly spaced time series, in combination wi...
Ordovician timescale in Estonia:recent developments
stratigraphy timescale Ordovician graptolites chitinozoans conodonts Estonia
2009/10/21
Over 150 years of progress in the Ordovician geology and stratigraphy of Estonia has resulted in one of the most precise Ordovician timescales in the world. In this paper, an up-to-date version of the...

We investigate the e®ects of correlated global regulation mecha-
nisms, especially Galactic gamma-ray bursts (GRBs), on the temporal distribution
of hypothetical inhabited planets, using simple ...

timescale analysis Northern Hemisphere temperature response
2008/11/12
The Northern Hemisphere temperature response to volcanic and solar forcing in the time interval 1000–1850 AD is studied using first a set of simulations with an intermediate-complexity climate model, ...
