Probing the composition of sub-millisecond rotating compact stars by r-modes instability [PDF]

, 2012
We investigate the implications of the r-modes instability on the composition of a compact star rotating at a sub-millisecond period. In particular, the only viable astrophysical scenario for such an object, wich might present inside the Low Mass X-ray ...

Accretion processes in AM Herculis systems [PDF]

, 2017
We begin by presenting a theoretical model for the radial velocity and velocity dispersion of the broad emission line component in AM Herculis systems assuming that it originates mainly in the gas which is diverted out of the orbital plane and ...

Gravitoastronomy with neutron stars [PDF]

, 2004
Recent advances in gravitational wave detectors mean that we can start to make astrophysically important statements about the physics of neutron stars based on observed upper limits to their gravitational luminosity.

Infrared and optical polarimetry of AM Herculis

, 1984
Circular polarization observations of AM Herculis have been obtained at wavelengths from 0.55 micron (V) to 2.2 micron (K) using a simultaneous three-channel polarimeter.

TESS Light Curves of Two New Magnetic Cataclysmic Variables: An Asynchronous Polar at the Period Minimum and an Eclipsing System with a Large Spin-to-orbit Ratio

The Astrophysical Journal
A recent development in the study of magnetic cataclysmic variable stars (mCVs) has been the identification of asynchronously spinning mCVs with orbital periods

Energy Transport in Radially Accreting White Dwarf Stars [PDF]

, 1986
AM Herculis stars form a subclass of cataclysmic variables, the defining characteristic of which is that they possess a high degree of polarisation at optical frequencies. Physically they have two notable features.

Wide binary stars in the Galactic field : a statistical approach [PDF]

, 2010
This thesis focuses on the statistical properties of wide binary (WB) star systems in the Galactic field. With projected separations larger than 200 AU and, consequently, having very low binding energies, WB are sensitive probes of the Galactic ...

EXO 023432-5232.3 - an eclipsing AM Herculis binary

, 1988
The authors report observations of the serendipitous EXOSAT source EXO 023432-5232.3 which confirm that the object is an AM Herculis type binary and show the presence of eclipses by the companion star.

Pulsation versus metallicism in Am stars as revealed by LAMOST and WASP [PDF]

, 2016
We present the results of a study of a large sample of A and Am stars with spectral types from LAMOST and light curves from WASP. We find that, unlike normal A stars, δ Sct pulsations in Am stars are mostly confined to the effective temperature range ...
