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
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...
Detection of Supergranulation Alignment in Polar Regions of the Sun by Helioseismology

We report on a new phenomenon of ‘alignment’ of supergranulation cells in the polar regions of the Sun. Recent high-resolution datasets obtained by the Solar Optical Telescope (SOT) onboard the Hinode...

Binaries are not always neatly aligned. Previous observations of the DI Her system showed that the spin axes of both stars are highly inclined with respect to one another and the orbital axis. Here we...
