On using the beaming effect to measure spin-orbit alignment in stellar binaries with Sun-like components
measure spin-orbit alignment stellar binaries Sun-like components

2011/10/13
The beaming effect (aka Doppler boosting) induces a variation in the observed flux of a luminous object, following its observed radial velocity variation. We describe a photometric signal induced by t...
Using Star Spots to Measure the Spin-orbit Alignment of Transiting Planets
Using Star Spots Measure Alignment Transiting Planets
font style='font-size:12px;'>
2011/10/8
Spectroscopic follow-up of dozens of transiting planets has revealed the degree of alignment between the equators of stars and the orbits of the planets they host. Here we determine a method, applicab...
A highly efficient measure of mass segregation in star clusters
Methods: numerical

As a formation route for objects such as giant planets and low-mass stars in protostellar discs (as well as stars in AGN discs), theories of self-gravitating disc fragmentation need to be able to pred...
Faraday Rotation Measure due to the Intergalactic Magnetic Field II: the Cosmological Contribution
Intergalactic Magnetic Field II Cosmological Contribution

2011/9/26
We investigate the Faraday rotation measure (RM) due to the intergalactic magnetic field (IGMF) through the cosmic web up to cosmological distances, using a model IGMF based on turbulence dynamo in th...
