Meridional Flow in the Solar Convection Zone II: Helioseismic Inversions of GONG Data
J. Jackiewicz, A. Serebryanskiy, S. Kholikov
Meridional flow is thought to play a very important role in the dynamics of the solar convection zone; however, because of its relatively small amplitude, precisely measuring it po…
Helioseismic Investigation of Modeled and Observed Supergranule Structure
K. DeGrave, J. Jackiewicz
The subsurface structure of an "average" supergranule is derived from existing HMI pipeline time-distance data products and compared to the best helioseismic flow model detailed in…
Results of a Search for gamma Dor and delta Sct Stars with the Kepler Spacecraft
Paul A. Bradley, Joyce A. Guzik, Lillian F. Miles +3
The light curves of 2768 stars with effective temperatures and surface gravities placing them near the gamma Doradus/delta Scuti instability region were observed as part of the Kep…
The Occurrence of Non-Pulsating Stars in the gamma Dor and delta Sct Pulsation Instability Regions: Results from Kepler Quarter 14-17 Data
Joyce A. Guzik, Paul A. Bradley, Jason Jackiewicz +3
In our 2013 Astronomical Review article, we discussed the statistics of variability for 633 faint spectral type A-F stars observed by the Kepler spacecraft during Quarters 6-13. We…
