Stability analysis of a tidally excited internal gravity wave near the centre of a solar-type star
planetary systems stars: rotation binaries: close hydrodynamics waves instabilities
2011/9/15
We perform a stability analysis of a tidally excited nonlinear internal gravity wave near the centre of a solar-type star in two-dimensional cylindrical geometry. The motivation is to understand the t...

At wide separations, planetary-mass and brown dwarf companions to solar type stars occupy a
curious region of parameters space not obviously linked to binary star formation or solar-system scale plan...
WASP-32b: A transiting hot Jupiter planet orbiting a lithium-poor, solar-type star
Earth and Planetary Astrophysics (astro-ph.EP)
2010/12/28
We report the discovery of a transiting planet orbiting the star TYC 2-1155-1. The star, WASP-32, is a moderately bright (V=11.3) solar-type star (Teff=6100 +- 100K, [Fe/H] = -0.13 +- 0.10).
