Direct Calculation of the Turbulent Dissipation Efficiency in Anelastic Convection

Kaloyan Penev, Joseph Barranco, Dimitar Sasselov

The current understanding of the turbulent dissipation in stellar convective zones is based on the assumption that the turbulence follows Kolmogorov scaling. This assumption is val…

Independent confirmation and refined parameters of the hot Jupiter XO-5b

A. Pál, G. Á. Bakos, J. Fernandez +14

We present HATNet observations of XO-5b, confirming its planetary nature based on evidence beyond that described in the announcement of Burke et al. (2008), namely, the lack of sig…

The Prograde Orbit of Exoplanet TrES-2b

Joshua N. Winn, John Asher Johnson, Norio Narita +7

We monitored the Doppler shift of the G0V star TrES-2 throughout a transit of its giant planet. The anomalous Doppler shift due to stellar rotation (the Rossiter-McLaughlin effect)…
