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…
Deep MMT Transit Survey of the Open Cluster M37 III: Stellar Rotation at 550 Myr
J. D. Hartman, B. S. Gaudi, M. H. Pinsonneault +6
In the course of conducting a deep (14.5 ~< r ~< 23), 20 night survey for transiting planets in the rich ~550 Myr old open cluster M37 we have measured the rotation periods of 575…
What Prevents Internal Gravity Waves From Disturbing the Solar Uniform Rotation?
Pavel A. Denissenkov, Marc Pinsonneault, Keith B. MacGregor
Internal gravity waves (IGWs) are naturally produced by convection in stellar envelopes, and they could be an important mechanism for transporting angular momentum in the radiative…
The Impact of Carbon Enhancement on Extra Mixing in Metal-Poor Stars
Pavel A. Denissenkov, Marc Pinsonneault
We critically examine the constraints imposed by carbon-enhanced metal-poor (CEMP) stars on the mixing mechanisms that operate in red giants. CEMP stars are created when the surfac…
Deep MMT Transit Survey of the Open Cluster M37 II: Variable Stars
J. D. Hartman, B. S. Gaudi, M. J. Holman +5
We have conducted a deep ($15 \la r \la 23$), 20 night survey for transiting planets in the intermediate age () open cluster M37 (NGC 2099) using the Megacam wi…
Deep MMT Transit Survey of the Open Cluster M37 I: Observations and Cluster Parameters
J. D. Hartman, B. S. Gaudi, M. J. Holman +6
We have conducted a deep ($15 \la r \la 23$), 20 night survey for transiting planets in the intermediate age open cluster M37 (NGC 2099) using the Megacam wide-field mosaic CCD cam…
