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…
First Results From New 3D Spectral Simulations Of Anelastic Turbulent Convection
Kaloyan Penev, Joseph Barranco, Dimitar Sasselov
We have adapted the anelastic spectral code of Barranco & Marcus (2006) to simulate a turbulent convective layer with the intention of studying the effectiveness of turbulent eddie…
Deep MMT Transit Survey of the Open Cluster M37 IV: Limit on the Fraction of Stars With Planets as Small as 0.3 R_J
J. D. Hartman, B. S. Gaudi, M. J. Holman +6
We present the results of a deep (15 ~< r ~< 23), 20 night survey for transiting planets in the intermediate age open cluster M37 (NGC 2099) using the Megacam wide-field mosaic CCD…
Three-Dimensional Simulations of Kelvin-Helmholtz Instability in Settled Dust Layers in Protoplanetary Disks
Joseph A. Barranco
As dust settles in a protoplanetary disk, a vertical shear develops because the dust-rich gas in the midplane orbits at a rate closer to true Keplerian than the slower-moving dust-…
A Search for Transiting Hot Planets as Small as Neptune in the Open Cluster M37
J. D. Hartman, B. S. Gaudi, M. J. Holman +3
We are conducting a transit survey of the open cluster M37 using the Megacam instrument on the 6.5 m Multiple-Mirror Telescope. We have obtained ~4500 images of this cluster over 1…
A 3D Spectral Anelastic Hydrodynamic Code for Shearing, Stratified Flows
Joseph A. Barranco, Philip S. Marcus
We have developed a three-dimensional (3D) spectral hydrodynamic code to study vortex dynamics in rotating, shearing, stratified systems (e.g. the atmosphere of gas giant planets,…
