Misaligned spin and orbital axes cause the anomalous precession of DI Herculis
Simon Albrecht, Sabine Reffert, Ignas A. G. Snellen +1
The orbits of binary stars precess as a result of general relativistic effects, forces arising from the asphericity of the stars, and forces from additional stars or planets in the…
HAT-P-7: A Retrograde or Polar Orbit, and a Third Body
Joshua N. Winn, John Asher Johnson, Simon Albrecht +4
We show that the exoplanet HAT-P-7b has an extremely tilted orbit, with a true angle of at least 86 degrees with respect to its parent star's equatorial plane, and a strong possibi…
A Third Exoplanetary System with Misaligned Orbital and Stellar Spin Axes
John A. Johnson, Joshua N. Winn, Simon Albrecht +3
We present evidence that the WASP-14 exoplanetary system has misaligned orbital and stellar-rotational axes, with an angle lambda = 33.1 +/- 7.4 deg between their sky projections.…
The changing phases of extrasolar planet CoRoT-1b
Ignas A. G. Snellen, Ernst J. W. de Mooij, Simon Albrecht
Hot Jupiters are a class of extrasolar planet that orbit their parent stars at very short distances. Due to their close proximity, they are expected to be tidally locked, which can…
