On the augmented density of a spherical anisotropic dynamic system
J. An
This paper presents a set of new conditions on the augmented density of a spherical anisotropic system that is necessary for the underlying two-integral phase-space distribution fu…
Modified Virial Formulae and the Theory of Mass Estimators
J. An, N. W. Evans
We show how to estimate the enclosed mass from the observed motions of an ensemble of test particles. Traditionally, this problem has been attacked through virial or projected mass…
An investigation of magnetic field distortions in accretion discs around neutron stars - II. Analysis of the toroidal field component
L. Naso, J. C. Miller
Millisecond pulsars are believed to be old pulsars spun up by a surrounding accretion disc. Magnetic fields are thought to play a leading role in this, both by determining the loca…
Microwave Quasi-periodic Pulsations in Multi-timescales Associated with a Solar Flare/CME Event
Baolin Tan, Yin Zhang, Chengming Tan +1
Microwave observations of quasi-periodic pulsations (QPP) in multi-timescales are confirmed to be associated with an X3.4 flare/CME event at Solar Broadband Radio Spectrometer in H…
Constraints of a pulsation frequency on stellar parameters in the eclipsing spectroscopic binary system: V577 Oph
O. L. Creevey, J. Telting, J. A. Blemonte +7
We present a preliminary spectroscopic analysis of the binary system V577Oph, observed during the summer of 2007 on the 2.6m NOT telescope on La Palma. We have obtained time series…
Multi-timescale Solar Cycles and the Possible Implications
Baolin Tan
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-y…
