The ages of the disk clusters NGC 188, M67, and NGC 752, using improved opacities and cluster membership data

Guenther, David B.; Dinescu, Dana I.; Demarque, Pierre; Pinsonneault, M. H. (American Astronomical Society, 1995-05)

Theoretical isochrones have been constructed using the OPAL opacities to derive the ages of the open clusters NGC 188, M67, and NGC 752 as well as to estimate the amount of convective overshoot at the convective core edge. ...
The run of superadiabaticity in stellar convection zones. II. Effect of photospheric convection on solar p-mode frequencies

Demarque, Pierre; Guenther, David B.; Kim, Yong-Cheol (American Astronomical Society, 1999-05-20)

Kim and Chan have completed a three-dimensional numerical simulation of the interaction between turbulent convection and radiation in and above the highly superadiabatic layer (SAL) in the Sun. They have shown that the ...
Space- and ground-based pulsation data of [eta] Bootis explained with stellar models including turbulence

Straka, Christian W.; Demarque, Pierre; Guenther, David B.; Li, Linghuai; Robinson, Frank J. (American Astronomical SocietyIOP PUblishing, 2006-01-10)

The space telescope MOST is now providing us with extremely accurate low-frequency p-mode oscillation data for the star [eta] Boo.We demonstrate in this paper that these data, when combined with ground-based measurements ...
