I. Reconstructing Three-Dimensional Jet Geometry from Two-Dimensional Images

Sailee M. Sawant, Katie Kosak, Kunyang Li +3

We present a three-dimensional (3-D) visualization of jet geometry using numerical methods based on a Markov Chain Monte Carlo (MCMC) and limited memory Broyden-Fletcher-Goldfarb-S…

A Multi-Instrument Investigation of the Frequency Stability of Oscillations Above the Acoustic Cut-Off Frequency with Solar Activity

K. Kosak, R. Kiefer, A. M. Broomhall

Below the acoustic cut-off frequency, oscillations are trapped within the solar interior and become resonant. However, signatures of oscillations persist above the acoustic cut-off…

The JetCurry Code. I. Reconstructing Three-Dimensional Jet Geometry from Two-Dimensional images

Kunyang Li, Katie Kosak, Sayali S. Avachat +1

We present a reconstruction of jet geometry models using numerical methods based on a Markov ChainMonte Carlo (MCMC) and limited memory Broyden-Fletcher-Goldfarb-Shanno (BFGS) opti…

2-D and 3-D Models of Convective Turbulence and Oscillations in Intermediate-Mass Main-Sequence Stars

Joyce A. Guzik, T. H. Morgan, N. J. Nelson +5

We present multidimensional modeling of convection and oscillations in main-sequence stars somewhat more massive than the Sun, using three separate approaches: 1) Using the 3-D pla…

Amplitude Variability in gamma Dor and delta Scuti stars observed by the Kepler Spacecraft

Joyce A. Guzik, Katie Kosak, Paul A. Bradley +1

The NASA Kepler spacecraft data revealed a large number of multimode nonradially pulsating gamma Dor and delta Sct variable star candidates. The high precision long time-series pho…

Measurements of the Sun's High Latitude Meridional Circulation

Lisa Rightmire-Upton, David H. Hathaway, Katie Kosak

The meridional circulation at high latitudes is crucial to the build-up and reversal of the Sun's polar magnetic fields. Here we characterize the axisymmetric flows by applying a m…
